1–12 Introduction to Variable-Frequency Drives Getting Started Introduction to Variable-Frequency Drives The Purpose of Motor Speed Control for Industry Hitachi inverters provide speed control for 3-phase AC induction motors. You connect AC power to the inverter, and connect the inverter to the motor.
L200 Inverter 1–13 Torque and Constant Volts/Hertz Operation Output voltage Getting Started In the past, AC variable speed drives used an open loop (scalar) technique to control speed. The constant-volts-per-hertz operation maintains a constant ratio between the applied voltage and the applied frequency. With these conditions, AC induction motors inherently delivered constant torque across the operating speed range. For some applications, this scalar technique was adequate.
1–14 Introduction to Variable-Frequency Drives Getting Started Inverter Output to the Motor The AC motor must be connected only to the inverter’s 3-Phase AC Motor output terminals. The output terminals are uniquely V/T2 labeled (to differentiate them from the input terminals) U/T1 with the designations U/T1, V/T2, and W/T3. This corresponds to typical motor lead connection designations T1, T2, and T3.
L200 Inverter 1–15 Intelligent Functions and Parameters The optional read/write programmer will let you read and write inverter EEPROM contents from the programmer. This feature is particularly useful for OEMs who need to duplicate a particular inverter’s settings in many other inverters in assembly-line fashion. Braking In general, braking is a force that attempts to slow or stop motor rotation.
1–16 Introduction to Variable-Frequency Drives Getting Started Velocity Profiles The L200 inverter is capable of sophisticated speed control. A graphical representation of Speed that capability will help you understand and configure the associated parameters. This manual makes use of the velocity profile 0 graph used in industry (shown at right). In the example, acceleration is a ramp to a set speed, and deceleration is a decline to a stop.
L200 Inverter 1–17 Frequently Asked Questions What is the main advantage in using an inverter to drive a motor, compared to alternative solutions? A. Q. The term “inverter” is a little confusing, since we also use “drive” and “amplifier” to describe the electronic unit that controls a motor. What does “inverter” mean? A. Q. That depends on the required precision, and the slowest speed the motor will must turn and still deliver torque.
1–18 Frequently Asked Questions Getting Started Q. Why doesn’t the motor have a neutral connection as a return to the inverter? A. Q. Does the motor need a chassis ground connection? A. Q. The motor theoretically represents a “balanced Y” load if all three stator windings have the same impedance. The Y connection allows each of the three wires to alternately serve as input or return on alternate half-cycles. Yes, for several reasons.
L200 Inverter Q. How will I know if my application will require resistive braking? Several options related to electrical noise suppression are available for the Hitachi inverters. How can I know if my application will require any of these options? A. Q. For new applications, it may be difficult to tell before you actually test a motor/drive solution. In general, some applications can rely on system losses such as friction to serve as the decelerating force, or otherwise can tolerate a long decel time.

3–5 L200 Inverter Operational Modes The RUN and PRG LEDs tell just part of the story; Run Mode and Program Modes are independent modes, not opposite modes. In the state diagram to the right, Run alternates with Stop, and Program Mode alternates with Monitor Mode. This is a very important ability, for it shows that a technician can approach a running machine and change some parameters without shutting down the machine.
3–6 “D” Group: Monitoring Functions “D” Group: Monitoring Functions You can access important system parameter values with the “D” Group monitoring functions, whether the inverter is in Run Mode or Stop Mode. After selecting the function code number for the parameter you want to monitor, press the Function key once to show the value on the display. In functions D005 and D006, the intelligent terminals use individual segments of the display to show ON/OFF status.

3–8 “D” Group: Monitoring Functions Local Monitoring During Network Operation The L200 inverter’s serial port may be connected to a network or to an external digital operator. During those times, the inverter keypad keys will not function (except for the Stop key). However, the inverter’s 4-digit display still provides the Monitor Mode function, displaying any of the parameters D001 to D007. Function B089, Monitor Display Select for Networked Inverter, determines the particular D00x parameter displayed.
3–9 L200 Inverter “F” Group: Main Profile Parameters The basic frequency (speed) profile is Output defined by parameters contained in the F002 F003 frequency “F” Group as shown to the right. The set running frequency is in Hz, but acceleraF001 tion and deceleration are specified in the time duration of the ramp (from zero to maximum frequency, or from maximum 0 frequency to zero). The motor direction t parameter determines whether the keypad Run key produces a FWD or REV command.
3–10 “A” Group: Standard Functions “A” Group: Standard Functions Control Source Settings The inverter provides flexibility in how you control Run/Stop operation and set the output frequency (motor speed). It has other control sources that can override the A001/ A002 settings. Parameter A001 sets the source selection for the inverter’s output frequency. Parameter A002 selects the Run command source (for FW or RV Run commands).

The following table lists all frequency source setting methods and their relative priority (“1” is the highest priority). Priority A001 Frequency Source Setting Method Refer to page...
3–13 L200 Inverter Basic Parameter Settings These settings affect the most fundamental behavior of the inverter—the outputs to the motor. The frequency of the inverter’s AC output determines the motor speed. You may select from three different sources for the reference speed. During application development you may prefer using the potentiometer, but you may switch to an external source (control terminal setting) in the finished application, for example.
3–14 “A” Group: Standard Functions Analog Input Settings Configuring Drive Parameters The inverter has the capability to accept an external analog input that can command the output frequency to the motor. Voltage input (0 –10V) and current input (4–20mA) are available on separate terminals ([O] and [OI], respectively). Terminal [L] serves as signal ground for the two analog inputs. The analog input settings adjust the curve characteristics between the analog input and the frequency output.

3–18 “A” Group: Standard Functions Be aware that running the motor at a low speed for a long time can cause motor overheating. This is particularly true when manual torque boost is ON, or if the motor relies on a built-in fan for cooling. NOTE: Manual torque boost applies only to constant torque (A044=00) and variable torque (A044=01) V/f control. Voltage Gain – Using parameter A045 you V can modify the voltage gain of the inverter (see 100% graph at right).

The upper limit must Lower not exceed the rating of the motor or A062 limit capability of the machinery.
3–22 “A” Group: Standard Functions Jump Frequencies – Some motors or machines exhibit resonances at particular speed(s), which can be destructive for prolonged running at those speeds. The inverter has up to three jump frequencies as shown in the graph. The hysteresis around the jump frequencies causes the inverter output to skip around the sensitive frequency values.
3–23 L200 Inverter PID Control When enabled, the built-in PID loop calculates an ideal inverter output value to cause a loop feedback process variable (PV) to move closer in value to the setpoint (SP). The frequency command serves as the SP. The PID loop algorithm will read the analog input for the process variable (you specify the current or voltage input) and calculate the output. • A scale factor in A075 lets you multiply the PV by a factor, converting it into engineering units for the process.
3–24 “A” Group: Standard Functions Automatic Voltage Regulation (AVR) Function The automatic voltage regulation (AVR) feature keeps the inverter output waveform at a relatively constant amplitude during power input fluctuations. This can be useful if the installation is subject to input voltage fluctuations. However, the inverter cannot boost its motor output to a voltage higher than the power input voltage. If you enable this feature, be sure to select the proper voltage class setting for your motor.
3–25 L200 Inverter Second Acceleration and Deceleration Functions The L200 inverter features two-stage acceleration and deceleration ramps. This gives flexibility in the profile shape. You can specify the frequency transition point, the point at which the standard acceleration (F002) or deceleration (F003) changes to the second acceleration (A092) or deceleration (A093). Or, you can use intelligent input [2CH] to trigger this transition.

3–30 “A” Group: Standard Functions ADD Frequency – The inverter can add or subtract an offset value to the output frequency setting which is specified by A001 (will work with any of the five possible sources). The ADD Frequency is a value you can store in parameter A145. The ADD Frequency is summed with or subtracted from the output frequency setting only when the [ADD] terminal is ON. Function A146 selects whether to add or subtract.

3–33 L200 Inverter you must set the thermal overload threshold in terms of current (amperes) for parameter B012. The range is 20% to 120% of the rated current for each inverter model. If the current exceeds the level you specify, the inverter will trip and log an event (error E05) in the history table. The inverter turns the motor output OFF when tripped. Separate settings are available for the second motor (if applicable) as shown in the following table. “B” Function Func.
3–34 “B” Group: Fine Tuning Functions Overload Restriction If the inverter’s output current exceeds a preset current level you specify during acceleration or constant speed, the overload restriction feature automatically reduces the output frequency to restrict the overload. This feature does not generate an alarm or trip event. You can instruct the inverter to apply overload restriction only during constant speed, thus allowing higher currents for acceleration.

We suggest that you first scan through the listing of inverter functions to gain a general familiarity. This chapter will build on that knowledge in the following ways: 1. Related functions – Some parameters interact with or depend on the settings in other functions.
L200 Inverter 4–3 Warning Messages for Operating Procedures Before continuing, please read the following Warning messages. WARNING: Be sure to turn ON the input power supply only after closing the front case. While the inverter is energized, be sure not to open the front case. Otherwise, there is the danger of electric shock. WARNING: Be sure not to operate electrical equipment with wet hands. Otherwise, there is the danger of electric shock.
4–4 Connecting to PLCs and Other Devices Connecting to PLCs and Other Devices Hitachi inverters (drives) are useful in many types of applications. During installation, the inverter keypad (or other programming device) will facilitate the initial configuration. After installation, the inverter will generally receive its control commands through the control logic connector or serial interface from another controlling device.
4–5 L200 Inverter Example Wiring Diagram The schematic diagram below provides a general example of logic connector wiring, in addition to basic power and motor wiring covered in Chapter 2. The goal of this chapter is to help you determine the proper connections for the various terminals shown below for your specific application needs.

L200 Inverter 4–7 Intelligent Terminal Listing Intelligent Inputs Use the following table to locate pages for intelligent input material in this chapter.
4–8 Intelligent Terminal Listing Intelligent Outputs Use the following table to locate pages for intelligent output material in this chapter.
L200 Inverter 4–9 Using Intelligent Input Terminals Terminals [1], [2], [3], [4], and [5] are identical, programmable inputs for general use. The input circuits can use the inverter’s internal (isolated) +24V field supply or an external power supply. This section describes input circuits operation and how to connect them properly to switches or transistor outputs on field devices. The L200 inverter features selectable sinking or sourcing inputs.
4–10 Using Intelligent Input Terminals The two diagrams below show input wiring circuits using the inverter’s internal +24V supply. Each diagram shows the connection for simple switches, or for a field device with transistor outputs. Note that in the lower diagram, it is necessary to connect terminal [L] only when using the field device with transistors. Be sure to use the correct SR/SK switch position shown for each wiring diagram.
L200 Inverter 4–11 The two diagrams below show input wiring circuits using an external supply. If using the upper wiring diagram, be sure to use a diode with the external supply. This will prevent a power supply contention in case the SR/SK switch is accidentally placed in the incorrect position. Be sure to use the correct SR/SK switch position shown for each wiring diagram.
4–12 Using Intelligent Input Terminals Forward Run/Stop and Reverse Run/Stop Commands: When you input the Run command via the terminal [FW], the inverter executes the Forward Run command (high) or Stop command (low). When you input the Run command via the terminal [RV], the inverter executes the Reverse Run command (high) or Stop command (low).
L200 Inverter 4–13 Multi-Speed Select The inverter can store up to 16 different target frequencies (speeds) that the motor output uses for steady-state run condition. These speeds are accessible through programming four of the intelligent terminals as binary-encoded inputs CF1 to CF4 per the table to the right. These can be any of the six inputs, and in any order. You can use fewer inputs if you need eight or fewer speeds.
4–14 Option Code Using Intelligent Input Terminals Terminal Symbol Function Name Input State Valid for inputs: C001, C002, C003, C004, C005 Required settings: F001, A001 = 02, A020 to A035 Notes: • When programming the multi-speed settings, be sure to press the Store key each time and then set the next multi-speed setting. Note that when the key is not pressed, no data will be set.
L200 Inverter 4–15 Jogging Command The Jog input [JG] is used to command the motor to rotate slowly in small increments for manual operation. The speed is limited to 10 Hz. The frequency for the jogging operation is set by parameter A038. Jogging does not use an acceleration ramp, so we recommend setting the jogging frequency A038 to 5 Hz or less to prevent tripping.
4–16 Using Intelligent Input Terminals External Signal for DC Braking When the terminal [DB] is turned ON, the DC braking feature is enabled. Set the following parameters when the external DC braking terminal [DB] is to be used: • A053 – DC braking delay time setting. The range is 0.1 to 5.0 seconds. Scenario 1 [FW, RV] [DB] 1 0 1 0 Output frequency • A054 – DC braking force setting. The range is 0 to 100%. t The scenarios to the right help show how DC braking works in various situations.
L200 Inverter 4–17 Set Second Motor If you assign the [SET] function to an intelligent input terminal, you can select between two sets of motor parameters. The second parameters store an alternate set of motor characteristics. When the terminal [SET] is turned ON, the inverter will use the second set of parameters to generate the frequency output to the motor. When changing the state of the [SET] input terminal, the change will not take effect until the inverter is stopped.
4–18 Using Intelligent Input Terminals Two-stage Acceleration and Deceleration When terminal [2CH] is turned ON, the Output inverter changes the rate of acceleration and frequency deceleration from the initial settings (F002 second and F003) to use the second set of accelerainitial tion/deceleration values. When the terminal is turned OFF, the inverter is returned to the 1 [2CH] original acceleration and deceleration time 0 (F002 acceleration time 1, and F003 decelera- [FW], 1 [RV] 0 tion time 1).
L200 Inverter 4–19 Free-run Stop When the terminal [FRS] is turned ON, the inverter stops the output and the motor enters the free-run state (coasting). If terminal [FRS] is turned OFF, the output resumes sending power to the motor if the Run command is still active. The free-run stop feature works with other parameters to provide flexibility in stopping and starting motor rotation.
4–20 Using Intelligent Input Terminals External Trip When the terminal [EXT] is turned ON, the inverter enters the trip state, indicates error code E12, and stops the output. This is a general purpose interrupt type feature, and the meaning of the error depends on what you connect to the [EXT] terminal. Even if the [EXT] input is turned OFF, the inverter remains in the trip state. You must reset the inverter or cycle power to clear the error, returning the inverter to the Stop Mode.
L200 Inverter 4–21 Unattended Start Protection If the Run command is already set when power is turned ON, the inverter starts running immediately after powerup. The Unattended Start Protection (USP) function prevents that automatic startup, so that the inverter will not run without outside intervention. When USP is active and you need to reset an alarm and resume running, either turn the Run command OFF, or perform a reset operation by the terminal [RS] input or the keypad Stop/reset key.
4–22 Using Intelligent Input Terminals Software Lock When the terminal [SFT] is turned ON, the data of all the parameters and functions (except the output frequency, depending on the setting of B031) is locked (prohibited from editing). When the data is locked, the keypad keys cannot edit inverter parameters. To edit parameters again, turn OFF the [SFT] terminal input. Use parameter B031 to select whether the output frequency is excluded from the lock state or is locked as well.
L200 Inverter 4–23 Analog Input Current/Voltage Select The [AT] terminal selects whether the inverter uses the voltage [O] or current [OI] input terminals for external frequency control. When intelligent input [AT] is ON, you can set the output frequency by applying a current input signal at [OI]-[L]. When the [AT] input is OFF, you can apply a voltage input signal at [O]-[L] to set the output frequency.
4–24 Using Intelligent Input Terminals Reset Inverter The [RS] terminal causes the inverter to execute the reset operation. If the inverter is in Trip Mode, the reset cancels the Trip state. [RS] When the signal [RS] is turned ON and OFF, the inverter executes the reset operation. The Alarm minimum pulse width for [RS] must be 12 ms signal or greater. The alarm output will be cleared within 30 ms after the onset of the Reset command. 12 ms minimum 1 0 approx.
L200 Inverter 4–25 Thermistor Thermal Protection Motors that are equipped with a thermistor can be protected from overheating. Input terminal [5] has the unique ability to sense a thermistor resistance. When the resistance value of the thermistor connected to terminal [TH] (6) and [L] is more than 3 k Ω ±10%, the inverter enters the Trip Mode, turns OFF the output to the motor, and indicates the trip status E35.
4–26 Using Intelligent Input Terminals Three-wire Interface Operation The 3-wire interface is an industry standard motor control interface. This function uses two inputs for momentary contact start/stop control, and a third for selecting forward or reverse direction. To implement the 3-wire interface, assign 20 [STA] (Start), 21 [STP] (Stop), and 22 [F/R] (Forward/Reverse) to three of the intelligent input terminals. Use a momentary contact for Start and Stop.
L200 Inverter 4–27 The diagram below shows the use of 3-wire control. STA (Start Motor) is an edge-sensitive input; an OFF-to-ON transition gives the Start command. The control of direction is level-sensitive, and the direction may be changed at any time. STP (Stop Motor) is also a level-sensitive input.
4–28 Using Intelligent Input Terminals PID ON/OFF and PID Clear The PID loop function is useful for controlling motor speed to achieve constant flow, pressure, temperature, etc. in many process applications. The PID Disable function temporarily suspends PID loop execution via an intelligent input terminal. It overrides the parameter A071 (PID Enable) to stop PID execution and return to normal motor frequency output characteristics. the use of PID Disable on an intelligent input terminal is optional.
L200 Inverter 4–29 Remote Control Up and Down Functions The [UP] [DWN] terminal functions can adjust the output frequency for remote control while the motor is running. The acceleration time and deceleration time of this function is same as normal operation ACC1 and DEC1 (2ACC1,2DEC1). The input terminals operate according to these principles: • Acceleration - When the [UP] contact is turned ON, the output frequency accelerates from the current value.
4–30 Using Intelligent Input Terminals It is possible for the inverter to retain the frequency set from the [UP] and [DWN] terminals through a power loss. Parameter C101 enables/disables the memory. If disabled, the inverter retains the last frequency before an UP/DWN adjustment. Use the [UDC] terminal to clear the memory and return to the original set output frequency. Option Code Terminal Symbol 27 UP 28 29 DWN UDC Function Name Remote Control UP Function (motorized speed pot.
L200 Inverter 4–31 Force Operation from Digital Operator This function permits a digital operator interface to override the following two settings in the inverter: • A001 - Frequency source setting • A002 - Run command source setting When using the [OPE] terminal input, typically A001 and A002 are configured for sources other than the digital operator interface for the output frequency and Run command sources, respectively.
4–32 Using Intelligent Input Terminals ADD Frequency Enable The inverter can add or subtract an offset value to the output frequency setting which is specified by A001 (will work with any of the five possible sources). The ADD Frequency is a value you can store in parameter A145. The ADD Frequency is summed with or subtracted from the output frequency setting only when the [ADD] terminal is ON. Function A146 selects whether to add or subtract.
L200 Inverter 4–33 Force Terminal Mode The purpose of this intelligent input is to allow a device to force the inverter to allow control of the following two parameters via the control terminals: • A001 - Frequency source setting (01 = control terminals [FW] and [RV] • A002 - Run command source setting (01 = control terminals [O] or [OI] Some applications will require one or both settings above to use a source other than the terminals.
4–34 Using Intelligent Output Terminals Using Intelligent Output Terminals The intelligent output terminals are programmable in a similar way to the intelligent input terminals. The inverter has several output functions that you can assign individually to three physical logic outputs. Two of the outputs are open-collector transistors, and the third output is the alarm relay (form C – normally open and normally closed contacts).
L200 Inverter 4–35 Internal Relay Output The inverter has an internal relay output with normally open and normally closed contacts (Type 1 form C). The output signal that controls the relay is configurable; the Alarm Signal is the default setting. Thus, the terminals are labeled [AL0], [AL1], [AL2], as shown to the right. However, you can assign any one of the nine intelligent outputs to the relay.
4–36 Using Intelligent Output Terminals Output Signal ON/OFF Delay Function Intelligent outputs including terminals [11], [12], and the output relay, have configurable signal transition delays. Each output can delay either the OFF-to-ON or ON-to-OFF transitions, or both. Signal transition delays are variable from 0.1 to 100.0 seconds. This feature is useful in applications that must tailor inverter output signals to meet timing requirements of certain external devices.
L200 Inverter 4–37 Run Signal When the [RUN] signal is selected as an intelligent output terminal, the inverter outputs a signal on that terminal when it is in Run Mode. The output logic is active low, and is the open collector type (switch to ground). [FW], 1 [RV] 0 B082 Output freq. start freq.
4–38 Using Intelligent Output Terminals Frequency Arrival Signals The Frequency Arrival group of outputs help coordinate external systems with the current velocity profile of the inverter. As the name implies, output [FA1] turns ON when the output frequency arrives at the standard set frequency (parameter F001). Output [FA2] relies on programmable accel/ decel thresholds for increased flexibility.
4–39 L200 Inverter Frequency arrival output [FA1] uses the Output standard output frequency (parameter freq. F001) as the threshold for switching. In the figure to the right, Frequency Arrival [FA1] turns ON when the output frequency gets within 0.5 Hz below or 1.5 Hz above the target constant 0 frequency. This provides hysteresis that prevents output chatter near the threshold FA1 value.The hysteresis effect causes the signal output to turn ON slightly early as the speed approaches the threshold.
4–40 Using Intelligent Output Terminals Overload Advance Notice Signal When the output current exceeds a preset value, the [OL] terminal signal turns ON. The parameter C041 sets the overload threshold. The overload detection circuit operates during powered motor operation and during regenerative braking. The output circuits use open-collector transistors, and are active low.
L200 Inverter 4–41 Output Deviation for PID Control The PID loop error is defined as the magnitude (absolute value) of the difference between the Setpoint (target value) and the Process Variable (actual value). When the error magnitude exceeds the preset value for C044, the [OD] terminal signal turns ON. Refer to “PID Loop Operation” on page 4–54.
4–42 Using Intelligent Output Terminals Alarm Signal The inverter alarm signal is active when a fault has occurred and it is in the Trip Mode (refer to the diagram at right). When the fault is cleared the alarm signal becomes inactive. STOP RESET Run Stop RUN STOP RESET We must make a distinction between the alarm Fault Trip Fault signal AL and the alarm relay contacts [AL0], [AL1] and [AL2].
L200 Inverter 4–43 The alarm relay output can be configured in two main ways: • Trip/Power Loss Alarm – The alarm relay is configured as normally closed (C036=1) by default, shown below (left). An external alarm circuit that detects broken wiring also as an alarm connects to [AL0] and [AL1]. After powerup and short delay (< 2 seconds), the relay energizes and the alarm circuit is OFF. Then, either an inverter trip event or an inverter power loss will de-energize the relay and open the alarm circuit.
4–44 Using Intelligent Output Terminals Analog Input Disconnect Detect This feature is useful when the inverter receives a speed reference from an external device. Upon input signal loss at either the [O] or [OI] terminal, the inverter normally just decelerates the motor to a stop. However, the inverter can use the intelligent output terminal [Dc] to signal other machinery that a signal loss has occurred. Voltage signal loss at [O] terminal - Parameter B082 is the Start Frequency Adjustment.
4–45 L200 Inverter PID Second Stage Output The inverter has a built-in PID loop feature for two-stage control, useful for certain applications such as building ventilation or heating and cooling (HVAC). In an ideal control environment, a single PID loop controller (stage) would be adequate. However, in certain conditions, the maximum output energy from the first stage is not enough to maintain the Process Variable (PV) at or near the Setpoint (SP). And, the output of the first stage is in saturation.
4–46 Using Intelligent Output Terminals To use the PID Second Stage Output feature, you will need to choose upper and lower limits for the PV, via C053 and C052 respectively. As the timing diagram below shows, these are the thresholds Stage #1 inverter uses to turn ON or OFF Stage #2 inverter via the [FBV] output. The vertical axis units are percent (%) for the PID setpoint, and for the upper and lower limits. The output frequency, in Hz, is superimposed onto the same diagram.

4–48 Using Intelligent Output Terminals Network Detection Signal The Network Detection Signal output indicates the general status of network communications. The inverter has a programmable watchdog timer to monitor network activity. Parameter C077 sets the time-out period. If communications stop or pause longer than the specified time-out period, the Ndc output turns ON.
4–49 L200 Inverter Master Slave Watchdog timer C077 =xx.xx sec. Time-out [NDc] Alarm C076 =00 or 01 t Logic Output Function The Logic Output Function uses the inverter’s built-in logic feature. You can select any two of the other nine intelligent output options for internal inputs (use C141 and C142). Then, use C143 to configure the logic function to apply the logical AND, OR, or XOR (exclusive OR) operator as desired to the two inputs.

L200 Inverter 4–51 Analog Input Operation The L200 inverters provide for analog input to command the inverter frequency output value. The analog input terminal group includes the [L], [OI], [O], and [H] terminals on the control connector, which provide for Voltage [O] or Current [OI] input. All analog input signals must use the analog ground [L]. If you use either the voltage or current analog input, you must select one of them using the logic input terminal function [AT] analog type.
4–52 Analog Input Operation The following table shows the available analog input settings. Parameter A005 and the input terminal [AT] determine the External Frequency Command input terminals that are available, and how they function. The analog inputs [O] and [OI] use terminal [L] as the reference (signal return).
4–53 L200 Inverter Analog Output Operation In inverter applications it is useful to monitor the inverter operation from a remote location or from the front panel of an inverter enclosure. In some cases, this requires only a panel-mounted volt meter. In other cases, a controller such as a PLC may provide the inverter’s frequency command, and require inverter feedback data (such as output frequency or output current) to confirm actual operation. The analog output terminal [AM] serves these purposes.
4–54 PID Loop Operation PID Loop Operation In standard operation, the inverter uses a reference source selected by parameter A001 for the output frequency, which may be a fixed value (F001), a variable set by the front panel potentiometer, or value from an analog input (voltage or current). To enable PID operation, set A071 = 01. This causes the inverter to calculate the target frequency, or setpoint. A calculated target frequency can have a lot of advantages.
L200 Inverter 4–55 PID Loop Configuration The inverter’s PID loop algorithm is configurable for various applications. PID Output Limit - The PID loop controller has a built-in output limit function. This function monitors the difference between the PID setpoint and the loop output (inverter output frequency), measured as a percentage of the full scale range of each. The limit is specified by parameter A078.
4–56 Configuring the Inverter for Multiple Motors Configuring the Inverter for Multiple Motors Simultaneous Connections For some applications, you may need to connect two or more motors (wired in parallel) to a single inverter’s output. For example, this is common in conveyor applications where two separate conveyors need to have approximately the same speed. The use of two motors may be less expensive than making the mechanical link for one motor to drive multiple conveyors.
L200 Inverter 4–57 Having two motor profiles lets you store two “personalities” for motors in one inverter’s memory. The inverter allows the final selection between the two motor types to be made in the field through the use of an intelligent input terminal function [SET]. This provides an extra level of flexibility needed in particular situations. See the following table. Parameters for the second motor have a function code of the form x2xx.

B–2 Introduction Introduction L200 Series inverters have built-in RS-485 serial communications, featuring the ModBus RTU protocol. The inverters can connect directly to existing factory networks or work with new networked applications, without any extra interface equipment. The specifications for L200 serial communications are in the following table.
L200 Inverter B–3 Connecting the Inverter to ModBus Follow the steps in this section to connect the inverter to the ModBus network. 1. Open Serial Port Cover - The inverter keypad has a hinged dust cover protecting the serial port connector. Lift the cover from the bottom edge, and tilt upward as shown (below left). 2. Modular Interconnect Removal - With the serial port cover opened, notice the RJ45 modular connector behind it.
B–4 Connecting the Inverter to ModBus 4. Terminate Network Wiring - The RS-485 wiring must be terminated at each physical end to suppress electrical reflections and help decrease transmission errors. The L200 communications port does not include a termination resistor. Therefore, you will need to add termination to the inverter if it is at the end of the network wiring. Select termination resistors that match the characteristic impedance of the network cable.
L200 Inverter B–5 6. Inverter Parameter Setup - The inverter has several settings related to ModBus communications. The table below lists them together.

CE–EMC Installation Guidelines In This Appendix.... D page — CE–EMC Installation Guidelines ..................... 2 — Hitachi EMC Recommendations .....................
D–2 CE–EMC Installation Guidelines CE–EMC Installation Guidelines You are required to satisfy the EMC directive (89/336/EEC) when using an L200 inverter in an EU country. To satisfy the EMC directive and to comply with standard, follow the guidelines in this section. 1. As user you must ensure that the HF (high frequency) impedance between adjustable frequency inverter, filter, and ground is as small as possible.
L200 Inverter D–3 4. Take measures to minimize interference that is frequently coupled in through installation cables. • Separate interfering cables with 0.25m minimum from cables susceptible to interference. A particularly critical point is laying parallel cables over longer distances. If two cables intersect (one crosses over the other), the interference is smallest if they intersect at an angle of 90°.
D–4 CE–EMC Installation Guidelines L200 inverter designed for use in Europe (–xxxLFEF/xxxHFEF models) have built-in line filters. In the event your application needs additional filtering, the following diagrams show control panel mounting and wiring examples for different filter types.
