GP 6.5.8 Check M15 and M21
WARNING
Moving Parts, keep hands clear of the eWire when
performing motor checks. Make sure that power is
disconnected from the machine before touching any
moving parts.
Locate Motor M15 and M21:
•
Open the lid and raise the lower bypass panel.
•
M15 drives the linear travel belt for the Holder Module. M21
drives the linear travel belt for the Closer Module.
1. To check the motor function, manually move the Closer Module and
Holder Module forward. When an interlock cheater is inserted, the
Closer and Holder will return to their home positions (at the far right of
the eWire).
Motors return to home position as expected
Yes- Return to the RAP that directed you here
No- Go to Step 2.
2. Make sure the motor wire is connected securely at the Driver Board
and at the Main Control Board (PL 5.27). Do REP 1.5 to remove the
Rear Cover to gain access to the connector at the Control Board. The
motor Driver boards are located on the rear of the eWire Frame.
All the connectors are securely connected.
Yes- Go to Step 3
No- Make the connection and resume operation
3. Inspect the timing belt. Confirm that the belt is not frayed or worn and
that no teeth are missing.

from the Main Control board.
If LED 2 is lit, it means there is a fault with either the Driver board or
the stepper motor.

7. Check that the cable(s) connecting the Driver Board to the Main
Control Board are intact. Refer to the motor cables table to identify
the appropriate cable part numbers,
