Troubleshooting
1. Check TQ LIM
setting (page 41).
2. “Fix” load (i.e.,
straighten
mounting,
coupling, etc.); or
replace motor and
drive with motor
and drive rated for
higher horsepower.
3. Compare motor
voltage to input
voltage. Replace
motor if necessary.
TQ is unsatisfactory at
high speeds.
1. TQ LIMIT set too low.
2. Load may exceed
rating of motor/drive.
3. Nominal input voltage
may be too low for
motor.
