6.4.2.2. Offsetting Analog Command
l You may adjust offset value of command voltage with the parameter AF.
l Offset adjustment of the Driver Unit has been made at the shipping. With the parameter AF,
reset the offset in accordance with the master controller.
l The parameter AF sets the offset value by -4.9 mV per parameter data in the range of AF -63 to
AF 63.
