motor_ActualPostion tag to evaluate the encoder installation.
1. Disable the drive.
2. Note the ActualPostion tag value.
3. Move the axis in the positive direction.
See
for definition for positive direction.
4. Verify that the ActualPostion tag value increases as the axis
moves.
If the positive direction of travel does not match what has been
defined by the motor power and Hall Sensing wiring, then
change the direction by re-wiring the encoder using the
following table.
