Troubleshooting
12. The Motor is Running But at an Abnormal Speed
The motor is
running but at an
abnormal speed.
Are all electrical
connections between
the "FREQ" plug on
the main board and
the AC drive secure?
Secure any loose
connections. Refer to the
schematic supplied with the
machine for wiring
information.
Recalibrate the main board
by following the directions
listed in the programming
manual that was supplied
with the machine.
After recalibrating the main
board, does the motor still
run at an abnormal speed?
Using a parameter unit, check the
parameter set for your AC drive.
Contact Alliance Laundry Systems'
customer service department with
your machine's model and serial
number to obtain the proper AC
drive illustration.
