Table 4-1. Troubleshooting Chart (Continued)
POSSIBLE CAUSE
Current Limiter in the rotation
VFD is activating.
VFD parameter settings are
incorrect.
Machine's supply voltage is too
low.
Loose connections in the rotation
circuit.
Motor Failure.
Reducer Failure.
SOLUTION
Check for a mechanical bind in the rota-
tion mechanicals, such as: worn bearing(s)
or casters, incorrectly tensioned chain,
worn chain, alignment issues etc.
Identify and repair or replace worn parts.
Review the parameter settings in the VFD.
Refer to the supplied VFD Manual for
procedure.
Refer to the VFD manual and the Orion
parameter settings sheet supplied with the
machine for maximum frequency settings.
Check AC voltage (at the On-Off switch
terminals) while the machine is running
under load.
If voltage drops below 115, the supply is
not strong enough to run the machine cor-
rectly. Contact plant electrician. Do not
use household extension cords with the
machine.
Remove power from machine. Check for
loose connections in the rotation circuit
such as; Primary supply to the rotation
VFD, Secondary supply from the VFD to
the drive motor and all connections in
between.
Re-seat all loose connections. Tighten
connections correctly.
Perform motor test per motor manufac-
turer's recommendations.
Replace motor as needed.
Remove rotation reducer-separate motor
from reducer. Rotate input shaft and check
for binding.
Replace reducer as needed.
