3b. Motor Controller

■

Check power to motor controller board:

➔

P1 of the motor control board should have 120 VAC

across its two terminals

when the motor controller

is powered

. See Test #3. Replace the motor control

board if connector is broken.

■

Check link between machine controller and motor

controller:

➔

With the power disconnected

, check connectivity

between P4 of the machine controller and P2 of the

motor controller. Replace upper harness if necessary.

Replace control board if connector is broken.

■

Check fuse:

➔

With the power disconnected, check for an open

fuse. You may have to scratch away conformal

coating from the bare metal of the fuse before

checking for continuity.

➔

If there is a problem with any component of the motor

control board, replace the entire board.

3c. Wiring and Drive Motor

■

Check the drive motor windings by removing connectors

P6 from the motor controller board. Check for the

resistance values shown in Table 3. For ground contact,

use a ground screw attached to the top.

■

If the winding measurements are much higher (tens of

Ohms to infinity) than shown in Table 3, a problem exists

in the motor winding or in the connection between the

control board and the motor. Check the resistance at the

drive motor. Remove the connector at the motor, and

take measurements as shown in Table 4.

Measure resistance directly across the motor windings

where these colored wires enter the motor.

■

If the resistance is much higher (tens of Ohms to infinity)

than shown in Table 4, replace the drive motor.

■

If the resistance at the drive motor is correct, there is an

open circuit in the wiring between the motor and control

board. Repair or replace the lower wiring harness.
