TQ LIMIT LED
The yellow TQ LIMIT LED is on when the drive output
current exceeds the threshold set by the TQ LIMIT trimpot.
When the TQ LIMIT LED turns on, shut down the motor and
drive by disabling or removing power. Check the motor to
make sure it is not jammed or overloaded. The TQ LIMIT
trimpot may need to be recalibrated. See the Calibration
section (page 47) for information on calibrating the TQ
LIMIT trimpot.
