6.3.6.4. Analog Command Input Offset
 Setting of the parameter AF for analog command voltage offset enables tuning of the analog command
voltage offset.
 The parameter AF for analog command voltage offset is not tuned for the Driver Unit when shipped, so
tune the offset after connecting to your controller.
 The parameter AF for analog command voltage offset is 0.3 [mV] per data, and setting range is AF-3276
to AF-3276.

 The unit of the set value is 0.3 [mV].
 "RANGE OVER?" appears when the calculated offset is too large. At this time, the current setting
programs are not changed.
