Broken motor shaft
Solution
Visually check circuit breaker for a tripped condition
Check incoming voltage to ensure it is above the
minimum operating voltage
Measure voltage across disconnect switch. Voltage
should measure between 190 and 264 Vac.
Check incoming voltage to ensure it is below the
maximum operating voltage
Replace the system settings file with a backup or new
file
Ensure that the first line in the settings.txt file contains
™
the text GMS . If not replace the file with the proper
system update file.
If error persists the motor will need to be replaced
Ensure the d-sub connector to the motor is connected
and the wiring is intact
Check that material rod is able to freely move
Make sure the directional valve has power
Make sure the directional valve has power
Make sure the cord to the directional valve is
connected to the correct port and the cord is not
damaged
The directional valve will need to be replaced
The hydraulic power pack will need repair
Replace encoder
Reset coupler per specifications and retighten set
screws
Retighten or replace supply tube
Replace motor
