Servo/Encoder Test

The servo/encoder test performs the following:

DMedia.axis encoder test: Verifies the operation of the servo loop (media.axis feedback).

DCarriage.axis encoder test: Verifies the operation of the servo loop (carriage.axis feedback).





DRecords the maximum pulse.width modulations used. You can view this information on the service configuration plot.

1In service mode 2:

Hold down the ALT key and press Servo/Encoder Test.

Test

The Load Media LED (or the Ready LED, if you have already loaded media) turns off, and the carriage moves over the left end of the roller. The roller rotates slightly.

The carriage moves to the center of the plotter. Both the carriage

and the roller then move backwards and forwards in cycles of six short steps, changing direction between cycles.

2Press any front.panel key to stop the test.

St￿tus. If the test does not find an error, the Load Media LED (or the Ready LED, if you have already loaded media) turns on again. If the test finds an error, it is indicated by an error code on the front panel.

Encoder Tests, Maximum Y-Axis PWM

(Y-Axis = Carriage Axis.) This should be less

 

than 102. Typical value = 75.

Encoder Tests, Maximum X-Axis PWM

(X-Axis = Media Axis.) This should be less than

 

65. Typical value = 52.
