(3) Control of IAI electric actuator controller parameters
Parameters set in IAI electric actuator controller are not controlled by Motion
CPU. They are set directly using IAI electric actuator controller data editing
software. For details on setting items for IAI electric actuator controller, refer to
the instruction manual of the IAI electric actuator controller.
