Rockwell Automation 160 FRN 5-6.XX Quick Reference Card - Manual (Page 4)

• Motor Does Not Start
(No output voltage to motor)
1. Check power circuit.
- Check supply voltage.
- Check all fuses and disconnects.
2. Check motor.
- Verify that motor is connected properly.
3. Check control input signals.
- Verify that START signal is present.
- Verify that STOP signal is present.
- Verify that RUN FORWARD and RUN REVERSE signals are
NOT both active.
4. Check P46 - [Input Mode].
- If P46 - [Input Mode] is set to “2”, only the program keypad
module start button will start the motor.
• Controller Started but Motor NOT Rotating
(P01 - [Output Frequency] displays “0.0”)
1. Check motor.
- Verify that motor is connected properly.
2. Check frequency source P06 - [Frequency Command].
- Verify that frequency signal is present at terminal block TB3.
–10 to +10V signal
4-20 mA signal
- Verify that Preset Frequencies are set properly.
3. Check control input signals.
- Verify that SW1, SW2 and SW3 are correct. (Refer to the
chart in the User Manual at the end of Chapter 5).
4. Check parameter settings.
- Verify that P59 - [Frequency Select] is showing desired fre-
quency source.
- Verify that P58 - [Internal Frequency] is the desired value.
• Motor Not Accelerating Properly
1. Check motor.
- Verify that motor is connected properly.
- Verify that no mechanical problems exist.
2. Check parameter settings.
- Verify that P30 - [Accel Time 1] or P69 - [Accel Time 2] is set
properly.
- Verify that P43 - [Current Limit] is set properly.
- Verify that P38 - [Boost Select] is set properly.
• Can Not Operate in “RUN FWD/RUN REV” Mode
1. Verify that P46 - [Input Mode] is set to “1”.
2. Verify that P73 - [Reverse Disable] or P74 - [Analog Select]
are not set to “1”.
3. Verify that power has been cycled for above change to take
effect.
4. Verify that both RUN FORWARD and RUN REVERSE switches
are NOT closed simultaneously.
Troubleshooting
38 Phase U Fault
Check the wiring between the controller and motor.
Check motor for grounded phase.
39 Phase V Fault
Check the wiring between the controller and motor.
Check motor for grounded phase.
40 Phase W Fault
Check the wiring between the controller and motor.
Check motor for grounded phase.
41 UV Short Fault
Check the motor and external wiring to the controller
output terminals for a shorted condition.
42 UW Short Fault
Check the motor and external wiring to the controller
output terminals for a shorted condition.
43 VW Short Fault
Check the motor and external wiring to the controller
output terminals for a shorted condition.
48 Reprogram Fault
Clear fault.
49 Zero Overload Fault
Reduce motor load at zero hertz. Reduce motor dwell
time at zero hertz. Reduce P38-[Boost Select].
