Operation
5.2.2 Servomotor Rotation Direction
The servomotor rotation direction can be reversed with parameter Pn000 without changing the polarity of the
speed/position reference.
This causes the travel direction of the motor change, but the encoder pulse output polarity does not change.
∗ The standard setting for “forward rotation” is counterclockwise (CCW) as viewed from the drive end.
