Troubleshooting
Drive displays an overcurrent fault (F001/F002) during motor startup.
Measure motor current during startup, check motor nameplate data against drive parameters, inspect motor windings for shorts.
Reduce acceleration time in drive parameters, verify motor is not overloaded, ensure motor parameters are correctly set, replace motor if windings are damaged.
Motor runs erratically or vibrates excessively.
Check motor connections for looseness, verify motor rotation direction matches load, check motor speed and frequency settings.
Tighten motor power and control connections, reverse motor leads if rotation is incorrect, adjust speed/frequency settings as per application requirements.
Drive shows a thermal fault (F003/F004) even with low motor load.
Verify ambient temperature around the drive and motor, check motor cooling fan operation, inspect drive heatsink for dust buildup.
Ensure operating environment is within specified temperature limits, clean drive heatsink and motor cooling fins, verify motor cooling fan is functioning correctly.
No output voltage from the drive.
Check input power supply voltage at drive terminals, verify drive is enabled and no faults are active, measure output voltage with a multimeter.
Confirm input power is present and within range, clear any active faults, check internal drive components if no output voltage is detected.
