Verifying Hookups

Then, do the following:

1. In the Hookups page of the Configure Axis Use dialog box, select the

Drive Offset button. The controller tests for drift, and displays a
message box containing the cumulative drift.

2. Go to the drive and manually adjust the drive offset potentiometer, so

that the drive is as near to perfectly still as possible.

3. In GML Commander, select OK. The message box closes, and GML

Commander completes the two-step test by internally performing its
own drive offset compensation.

Note: The Drive Offset test applies only to a Velocity Drive Interface

(as set in the Servo page).

For IMC S Class 1394/1394 Turbo controllers, GML Commander
includes this test as part of the Motor/Encoder test.
