Troubleshooting
Line fuse blows.
1. Line fuse is the wrong
size.
2. Motor cable or armature
is shorted to ground.
3. Nuisance tripping
caused by a combination
of ambient conditions
and high-current spikes
(i.e. reversing).
1. Check that the line fuse
is correct for the motor
size.
2. Check motor cable and
armature for shorts.
3. Add a blower to cool the
drive components;
decrease TORQUE
settings,
or
resize motor
and drive for actual load
demand,
or
check for
incorrectly aligned
mechanical components
or “jams”.
