(1) Automatic Adjustment of the Speed Reference Offset
The automatic adjustment of reference offset (Fn009) cannot be used when a position loop has been formed with
a host controller. Use the speed reference offset manual adjustment (Fn00A) described in the next section for a
position loop.
The zero-clamp speed control function can be used to force the motor to stop while the zero speed reference is
given. Refer to 9.7.6 Using the Zero Clamp Function.
The speed reference offset must be automatically adjusted with the servo OFF.
IMPORTANT
Adjust the speed reference offset automatically in the following procedure.
