POINT
Be sure to perform a home position return. Executing positioning operation
without home position return will trigger [AL. 90 Home position return incomplete
warning] and "Controlword bit 4 (New set-point)" will be disabled.
When travel distances to a target station position from CCW and from CW are
the same, the shaft will rotate to the station No. increasing direction.
This disables "Controlword bit 5 (Direction)". The following timing chart shows that an operation is
performed at a stop of the station No. 0 when servo-on.
