Table 7-1: Troubleshooting Guide
PROBLEM:
Drive Overcurrent Fault
Possible cause:
Motor ramp-up time too short.
Solution:
MTE suggests a ramp time of >5-10 seconds. Consult drive manufacturers
manual to configure proper parameters.
Possible cause:
Failed or incorrect wiring
Solution:
Verify all field and product wiring is correct.
Possible cause:
Parameter compatibility.
Solution:
Consult drive manufacturer’s manual for operating drive with a motor protection
filter.
Possible cause:
Filter, Drive, Motor current ratings incompatible.
Solution:
Verify the filter and motor are properly sized for the application.
Possible cause:
Drive not configured for Volts/ Hertz.
Solution:
Consult drive manufacturers manual to configure proper parameters.
Possible cause:
Motor winding fault.
Solution:
Verify motor windings and hi-pot is necessary.
Possible cause:
Cable failure.
Solution:
Verify cable continuity and insulation.
PROBLEM:
Excessive Filter Noise
Possible cause:
Mismatched motor rating.
Solution:
Verify the filter is properly sized for the application.
Possible cause:
Capacitors disconnected or improperly wired.
Solution:
Verify the proper connection of the capacitors.
Possible cause:
Carrier frequency less than 2 kHz.
Solution:
Verify the carrier frequency is at least 2 kHz.
PROBLEM:
Temperature Switch Open
Possible cause:
Mismatched motor rating.
Solution:
Verify the filter is properly sized for the application.
Possible cause:
Capacitors disconnected or improperly wired.
Solution:
Verify the proper connection of the capacitors.
Possible cause:
Carrier frequency less than 2 kHz.
Solution:
Verify the carrier frequency is at least 2 kHz.
Possible cause:
Excessive ambient temperature.
Solution:
Ensure filter is operating within specified ambient temperature below 60° C.
PROBLEM:
Motor will not turn.
Possible cause:
No power.
Solution:
Check fuses or breakers for proper input power.
Possible cause:
Motor incorrectly wired.
Solution:
Check for wiring faults.
Possible cause:
Locked rotor motor load.
Solution:
Check motor load.
Possible cause:
Drive fault.
Solution:
Consult drive manufacturers manual.
Possible cause:
Capacitors disconnected or improperly wired.
Solution:
Verify the proper connection of the capacitors.
Possible cause:
Overloaded motor.
Solution:
Verify the motor is properly sized for the application.
