The automatic adjustment of reference offset (Fn003) cannot be used when a position loop has been
formed with a host controller and the error pulse is changed to zero at the servomotor stop due to
servolock. Use the speed reference offset manual adjustment (Fn004) described in the next section for a
position loop.
The zero-clamp speed control function can be used to force the servomotor to stop while the zero speed
reference is given. Refer to
