Verify Motor Encoder
Direction
In this section, you use the monitor tags to evaluate the encoder installation.
1. Disable the drive.
2. Note the ActualPostion tag value.
3. Move the axis in the positive direction.
See page 43 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
rewiring the encoder by using the following table.
