1-8 General Information
Section 2 Installation This section describes the proper mounting and wiring of the BALDOR Series 10 Inverter. If problems arise, please refer to the troubleshooting information located in Section 4. Location and Mounting Select a mounting surface for the inverter that will allow the control to be mounted in a vertical position using the four mounting holes provided. The area selected should allow for free air circulation around the control.
Terminal Access Cover Removal To remove the Terminal Access Cover insert a small blade screwdriver into the slots located on the lower left and right hand corners of the access cover. Use a slight twisting motion while lifting upward to loosen one side. Use the same motion to loosen the other side then lift the cover off of the control. To reinstall, simply snap the cover back into place. See Figure 2-1 below.
Terminal and Jumper Locations Figure 2-2 shows the location of the power terminal strip , control terminal strip , ground lug, and user adjustable jumper locations. Only motor and input power should be connected to the power terminal strip. Motor ground and input power earth ground should be connected to the ground lug. Only external control wiring should be connected to control terminal strip.
Caution: Separate over-current protection may be required by the National Electrical Code. The installer of this equipment is responsible for complying with the National Electrical Code and any applicable local codes which govern such practices as wiring protection, grounding, disconnects, and other current protection. The inverter is self protected from normal AC line transients and surges. Additional external protection may be required if high energy transients are present on the incoming power source.
Caution: Do not use power factor correction capacitors on the input power lines to the inverter or damage to the control may result. All external control wiring to the inverter should be run in a separate conduit from all other wiring. The use of shielded twisted pair wire is recommended for all control wiring. The shield of the control wiring should be connected to control terminal CM of the inverter only. The other end of the shield should be taped to the wire jacket to prevent electrical shorts.
Recommended Terminal Tightening Torques Catalog g No. All Series 10 Caution: Tightening Torques Power Terminal TB1 Control Terminal Strip 10 In-Lb (1.13 Nm) 2 In-Lb (0.23 Nm) Do not use this control with any input voltage other than stated on the control nameplate. Use of control with wrong power source can damage the control. Main Circuit Wiring External or remote motor overload protection may be required by NEC or other regulator codes.
AC Power Connections Connect the fused three phase AC power lines to the input power terminals L1, L2, and L3. The phase rotation of the input power is not important since the control is not sensitive to phase rotation of the input power. For single phase AC power connect to input power terminals L1 and L2. Connect an earth ground to the inverter according to any applicable electrical code. The earth ground should be connected to the inverter chassis ground screw.
Motor Connections Connect the three phase power leads of the AC motor to terminals M1, M2, and M3 of the inverter power terminal strip. The motor ground lead or case ground should be connected to the inverter chassis ground screw. The motor should be connected to the inverter at all times during inverter operation. If additional motor overload protection is required, the use of suitably sized motor overload relays are recommended.
M-Contactor If required by local codes or for safety reasons, an M-Contactor (motor circuit contactor) may be installed. However, incorrect installation or failure of the M-Contactor or wiring may damage the control. Caution: If an M-Contactor is installed, the control must be disabled at least 20msec before the M-Contactor is opened. If the M-Contactor is opened while the control is supplying voltage and current to the motor, the control may me damaged.
Logic Wiring All logic and control connections are made at the control terminal strip located on the motor control board. Screw type terminals are provided for easy connection to your external control station and meters. The control terminal strip can be divided into four major categories as follows: 1) Analog command inputs. 2) Analog outputs. 3) Opto Isolated inputs. 4) Relay outputs. Analog Command Inputs An external 5kohm potentiometer can be connected at terminals CM, VIN, and REF.
Analog Output One programmable analog output is available for external monitoring of the drive condition. This output is available at terminals CM and MET. The output will be 0-10VDC. The positive lead of the external meter should be connected to terminal MET and the negative lead should be connected at terminal CM. The output condition is programmed in parameter 71-Analog Output Select. The analog output gain (max output voltage) can be adjusted in parameter 70- Analog Output Scale.
motor to coast to a stop. The fault or coast to stop operation of the MOL input terminal is selected by parameter 77-External Trip Select. The selection of pull- up or pull-down logic is set by jumper J19. Jumper J19 Input Selection Jumper J19 is a pin-jumper selector located to the left and below the control terminal strip (See Figure 2-2). Five jumper positions are available and are arranged in one group of three positions and one group of two positions with one shorting jumper in each group.
Relay Outputs Programmable relay outputs are available for external monitoring of the drive condition. These outputs are available at terminals NO (Normally Open) and NC (Normally Closed) with a common at terminal RCM (Relay Common). The circuit must be completed by connection at terminals NO or NC and returned to RCM. The output condition for terminals NO and NC is programmed in parameter 75- Relay Output Select. The relay outputs are rated at 115 VAC and 1 Amp maximum.

Section 3 Operation Keypad Key Functions The programming and basic operation of the Series 10 Inverter is accomplished by simple keystrokes on the operator control panel.
STOP Push to initiate a stop command. Depending on the setup of the control the motor will either ramp (Regen) or Coast to Stop. See 41-Accel/Decel/Coast Select in Section 3 for more information. FWD Used to initiate a forward direction run of the motor. REV Used to initiate a reverse direction run of the motor. PROG Used to access Level 1 Parameters. Holding the SHIFT key then pressing the PROG key will access Level 2 Parameters.
Arrow is also used to decrement the set speed in the Stop Mode and decrement the actual speed in the Run Mode. The value will decrease at a faster rate after holding the DOWN Arrow key for 5 seconds. Pressing SHIFT while holding the DOWN Arrow will bypass the 5 second delay. ENTER Used to store a new parameter value when in the Programming Mode. Also used in the Run and Stop Modes to store the current output frequency as the initial output frequency when power is applied to the inverter.
Description of Keypad Displays The custom, back-lit, LCD display provides information on drive operation and programming. The four large 7-segment displays show inverter output and programming data. Two smaller 7-segment displays are used to indicate parameter numbers. Special symbols and displays provide further clarification of drive operation. In normal operation only those segments that are active are displayed. The following figure shows all segments displayed.

Program Mode Use the Program Mode to customize the control to suit a variety of applications by programming the operating parameters. From the Stop Mode press the PROG key to access the Level 1 Program Mode. Hold the SHIFT key and press the PROG key to access the Level 2 Program Mode. When in the Program Mode press the SHIFT key then the UP/DOWN Arrow keys to change a parameter value. Pressing the ENTER key will save the new parameter value. To return to the Stop Mode, press the PROG key.
Level One Parameter Adjustments 07-Last Fault - A view only parameter that displays the most recent fault condition along with the elapsed time from the last restart of the control and the fault occurrence. The elapsed time is indicated in 0.1 hour increments with 0.9 hour maximum displayed. The two left most digits displayed is the fault code and the right most digits is the elapsed time. 12-Output Frequency - A view only parameter that displays inverter output frequency in Hertz applied to the motor.
21-Operating Mode - Sets the basic operation of the inverter input terminals and keypad FWD and REV keys. The Series 10 inverter has several modes of operation to fit various application requirements. Please refer to the following table to determine which operating mode is right for your application. The available options include keypad only, control terminal strip only, combination keypad and control terminal strip operation, electronic potentiometer, preset speeds, 2-wire control, and 3-wire control.

Note: Since the motor uses rotor slip to produce motor torque, the motor speed will not necessarily increase/decrease linearly with a linear increase/decrease in applied motor frequency. Some trial and error may be necessary to find the optimum Accel and Decel settings for your application. If the control trips (faults) during rapid accel or decel, selecting longer ramp times will help eliminate the trips.
67-Timed Overload Trip - Sets the amount of overload that will cause a Timed Overload fault (F20) to occur. A Timed Overload fault will occur when the output current reaches 150% of the set value for 1 minute. The Timed Overload Trip is active between 30-100% of the Inverter Rated Current (03-Rated Current) parameter value.
71-Analog Output Select - Allows setting of the analog output available at the control terminal MET to represent various drive operating conditions. The analog output is 0 to 10 VDC nominal. The analog output is useful in applications where a higher level control is monitoring the operation of the control to make process decisions based on the current status of the inverter. The output can also be used to drive remote analog meters that may be located near the operator.

51-V/HZ Profile - Sets the output V/Hz ratio for all values of output voltage verses output frequency up to the Control Base Frequency point. This adjustment will define how much voltage is applied to the motor in various segments of the output frequency range. Please note that motor voltage is related to motor current which can then be related to motor torque. By adjusting the V/Hz profile you can effectively adjust how much torque is available from the motor at various speed points.
53-Control Base Frequency - Sets the point on the V/Hz profile where the output voltage becomes a constant value with increasing output frequency. The base frequency point defines the output frequency where the motor goes from constant torque (or variable torque) to constant horsepower operation. The range of adjustment is from 26 to 960 HZ. The factory setting is 60 Hz. 59-Max. Output Volts - Sets the maximum output voltage available to the motor from the control.
62-Load Torque Limit REV - Sets the maximum amount of current that is supplied to the motor under a motoring reverse condition before Torque Limiting takes affect. The range of adjustment is 30- 150% of parameter 03-Rated Current. The factory setting is 150%. 63-Regen Torque Limit FWD - Sets the maximum amount of current that is absorbed by the control from the motor under a regenerative forward condition before Torque Limiting takes affect. The range of adjustment is 30-110% of parameter 03-Rated Current.
77-External Trip Select - Sets if the control will trip (Fault F07) or Coast to Stop if the condition at control terminal MOL is changed. If set to 0 or 1, then the control will automatically shut down indicating an External Trip (F07). If set to 2 or 3 the output to the motor is turned off and the motor is allowed to coast (free wheel) to a stop.
81-Factory Settings - If during start-up or operation you find the control operating parameters have been adjusted to the point of erratic or abnormal motor operation, the operating parameters can be reset to the factory settings (1). User parameter settings can also be stored (2) or recalled (3) for future use. The selected option will not execute until leaving the Program Mode and the display will prompt with SETP, STOC, or SETC when completed. The available options are listed in the table below.
If the inverter is set in an Auto Restart Mode and normal operation is using input power to start and stop the motor, the inverter may be started once every two minutes. The inverter will prevent operation if more frequent starts are commanded using line power connection. Synchro Starts - The Synchro Starts feature is desirable in applications where the motor shaft is rotating at the time that power is supplied to the motor from the inverter.
Parameter 82-Start Options - Continued Value Description Manual Restart.

Section 4 Troubleshooting Diagnostic Displays Several diagnostic displays are available from the keypad display to aid in trouble shooting the inverter. These displays may occur from normal operation or from a fault trip condition. Manual Restart (Line Start Lockout). See parameter 82–START OPTIONS for more information. Emergency Coast To Stop (Emergency Stop). See parameter 82–START OPTIONS for more information. Undervoltage Condition (Low Voltage). Input line voltage is too low. Typical Fault Display.
In the event of a fault trip, the display will show the fault code and the STATUS indicator will begin to blink red. Pressing the UP Arrow before the fault is reset will display the status of the drive at the time of the fault. More than one display symbol may be shown to better define the cause of the fault.
Maintenance The BALDOR Series 10 inverters require very little maintenance, if any, and should provide years of trouble free operation when installed and applied correctly. Occasional visual inspection should be considered to insure tight wiring connections and to avoid the build up of any dust, dirt, or foreign debris.
