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”.
See page 43 for
information on
adjusting the TORQUE
trimpot.
