The following table shows which models need derating.
Basic System Description A motor control system will obviously include a motor and inverter, as well as a circuit breaker or fuses for safety. If you are connecting a motor to the inverter on a test bench just to get started, that’s all you may need for now. But a system can also have a variety of additional components. Some can be for noise suppression, while others may enhance the inverter’s braking performance.
Determining Wire and Fuse Sizes The maximum motor currents in your application determines the recommended wore size. The following table gives the wire size in AWG. The “Power Lines” column applies to the inverter input power, output wires to the motor, the earth ground connection, and any other components shown in the “Basic System Description” on page 9. The “Signal Lines” column applies to any wire connecting to the two green connectors just inside the front cover panel.
Wire the Inverter Input to a Supply In this step, you will connect wiring to the input of the inverter. First, you must determine whether the inverter model you have required three-phase power only, or single-phase power only. All models have the same power connection terminals [R/L1], [S/L2], and [T/L3].

In general, the generator capacity should be five times that of the inverter (kVA).
Using the Front Panel Keypad Please take a moment to familiarize yourself with the keypad layout shown in the figure below. The display is used in programming the inverter’s parameters, as well as monitoring specific parameter values during operation.
Keys, Modes, and Parameters The purpose of the keypad is to provide a way to change modes and parameters. The term function applies to both monitoring modes and parameters. These are all accessible through function codes that are primary 4-character codes. The various functions are separated into related groups identifiable by the left-most character, as the table shows.

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.

Using Intelligent Input Terminals Terminals [1], [2], [3], [4], [5], [6] and [7] 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 WJ200 inverter features selectable sinking or sourcing inputs.
The two diagrams below 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 connection of the jumper wire shown for each wiring diagram.
The two diagrams below show input wiring circuits using an external supply. If using the “Sinking Inputs, External Supply” in below wiring diagram, be sure to remove the jumper wire, and use a diode (*) with the external supply. This will prevent a power supply contention in case the jumper wire is accidentally placed in the incorrect position. For the “Sourcing Inputs, External Supply”, please connect the jumper wire as drawn in the diagram below.
CAUTION: Be sure to diode in between "P24" and "PLC" when connecting plural inverters with digital input wiring in common. The power to the inverter control part can be supplied externally as shown below. Except driving motor, it is possible read and write the parameters by keypad and via communication even the drive itself is not powered. By having ability inverter doesn’t block the current flowing into itself when it is not powered.
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).
Multi-Speed Select ~Binary Operation 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.
Two Stage Acceleration and Deceleration When terminal [2CH] is turned ON, the inverter changes the rate of acceleration and deceleration from the initial settings (F002 and F003) to use the second set of acceleration/ deceleration values. When the terminal is turned OFF, the inverter is returned to the original acceleration and deceleration time (F002 acceleration time 1, and F003 deceleration time 1).
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.
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. When the signal [RS] is turned ON and OFF, the inverter executes the reset operation. The minimum pulse width for [RS] must be 12 ms or greater. The alarm output will be cleared within 30 ms after the onset of the Reset command. 12 ms minimum 1 [RS] 0 Approx.
Using Intelligent Output Terminals Run Signal When the [RUN] signal is selected as an 1 intelligent output terminal, the inverter outputs [FW,RV] 0 a signal on that terminal when it is in Run Mode. The output logic is active low, and is B082 Output the open collector type (switch to ground). frequency Run signal Option Code 00 Terminal Symbol RUN Valid for inputs: Required settings Function Name Run Signal State ON OFF start freq.
Frequency Arrival Signals The Frequency Arrival group of outputs helps 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. For example, you can have an output turn ON at one frequency during acceleration, and have it turn OFF at a different frequency during deceleration.
Frequency arrival output [FA1] uses the standard output frequency (parameter F001) as the threshold for switching. In the figure to the right, Frequency Arrival [FA1] turns ON when the output frequency gets within Fon Hz below or Fon Hz above the target constant frequency, where Fon is 1% of the set maximum frequency and Foff is 2% of the set maximum frequency. This provides hysteresis that prevents output chatter near the threshold value.
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. Run STOP RESET Stop RUN STOP RESET We must make a distinction between the alarm signal Trip AL and the alarm relay contacts [AL0], [AL1] and [AL2]. Fault Fault The signal AL is a logic function, which you can assign Alarm signal active to the open collector output terminals [11], [12], or the relay outputs.
The alarm relay output can be configured in two main ways: • Trip/Power Loss Alarm – The alarm relay is configured as normally closed (C036=01) 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.
Analog Input Operation The WJ200 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.
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).
Pulse Train Input Operation The WJ200 inverter is capable of accepting pulse train input signals, that are used for frequency command, process variable (feedback) for PID control, and simple positioning. The dedicated terminal is called “EA” and “EB”. Terminal “EA” is a dedicated terminal, and the terminal “EB” is an intelligent terminal, that has to be changed by a parameter setting. RS485 comm.
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.
The [AM] signal offset and gain are adjustable, as indicated below. Func. C106 C109 Description [AM] output gain [AM] output offset Range 0.~255. 0.0~10.0 Default 100. 0.0 The graph below shows the effect of the gain and offset setting. To calibrate the [AM] output for your application (analog meter), follow the steps below: 1. Run the motor at the full scale speed, or most common operating speed. a.

Monitoring Trip Events, History, & Conditions Trip History and Inverter Status We recommend that you first find the cause of the fault before clearing it. When a fault occurs, the inverter stores important performance data at the moment of the fault. To access the data, use the monitor function (dxxx) and select d081 details about the present fault. The previous 5 faults are stored in d082 to d086. Each error shifts d081-d085 to d082-d086, and writes the new error to d081.
Error Codes An error code will appear on the display automatically when a fault causes the inverter to trip. The following table lists the cause associated with the error. Error Code Name Cause(s) The inverter output was short-circuited, or the motor shaft is locked or has a heavy load. These conditions cause excessive current for the inverter, so the inverter output is turned OFF. The dual-voltage motor is wired incorrectly.

Error Code Name E81 Excessive speed E83 Positioning range error Cause(s) If the motor speed rises to "maximum frequency (A004) x over-speed error detection level (P026)" or more, the inverter will shut off its output and display the error code shown on the right. If current position exceeds the position range (P072-P073), the inverter will shut off its output and display the error code.
CE-EMC Installation Guidelines You are required to satisfy the EMC directive (2004/108/EC) when using an WJ200 inverter in an EU country. To satisfy the EMC directive and to comply with standard, you need to use a dedicated EMC filter suitable for each model, and follow the guidelines in this section. Following table shows the compliance condition for reference. Table 1. Condition for the compliance Model Cat. Carrier f Motor cable All WJ200 series C1 2kHz 20m (Shielded) Table 2.
4. 5. 6. 7. 8. • Ensure that the connections are metallic and have the largest possible contact areas (zinc-plated mounting plates). Avoid conductor loops that act like antennas, especially loops that encompass large areas. • Avoid unnecessary conductor loops. • Avoid parallel arrangement of low-level signal wiring and power-carrying or noise-prone conductors. Use shielded wiring for the motor cable and all analog and digital control lines.
protective conductor connection. The filter must be solidly and permanently connected with the ground potential so as to preclude the danger of electric shock upon touching the filter if a fault occurs. To achieve a protective ground connection for the filter: • Ground the filter with a conductor of at least 10 mm2 cross-sectional area. • Connect a second grounding conductor, using a separate grounding terminal parallel to the protective conductor.
Installation for WJ200 series (example of SF models) Model LFx (3-ph. 200V class) and HFx (3-ph. 400V class) are the same concept for the installation. Power supply 1-ph. 200V Metal plate (earth) The filter is a footprint type, so it is located between the inverter and the metal plate. Remove the insulation material coating of the earth contact portions so to obtain good grounding condition.
Hitachi EMC Recommendations WARNING: This equipment should be installed, adjusted, and serviced by qualified personal familiar with construction and operation of the equipment and the hazards involved. Failure to observe this precaution could result in bodily injury. Use the following checklist to ensure the inverter is within proper operating ranges and conditions. 1.
Functional Safety (Certification in Progress) Introduction The Gate Suppress function can be utilized to perform a safe stop according to the EN60204-1, stop category 0 (Uncontrolled stop by power removal). It is designed to meet the requirements of the ISO13849-1, PL=d only in a system in which EDM signal is monitored by an “external device monitor”.
(When safety switch or EDM switch is turned off, the intelligent input and output terminal assigned on will be set as "no" function, and contact will remain normally off.) Always use both inputs to disable the drive. If for any reason only one channel is opened, the drive output is stopped but the EDM output is not activated. In this case the Safe Disable input wiring must be checked. Installation According to the safety standard listed above, please install referring to the example.
Wiring example When the Gate Suppress function is utilized, connect the drive to a safety certified interrupting device utilizing EDM output signal to reconfirm both safety inputs GS1 and GS2.
Inverter doesn’t block the current flowing into itself when it is not powered. This may cause the closed circuit when two or more inverters are connected to common I/O wiring as shown below to result in unexpected turning the on the input. This may lead to dangerous situation. To avoid this closed circuit, please put the diode (rated:50V/0.1A) in the path as described below.
