9.7.3 Adjusting Offset
When using the speed control, the servomotor may run slowly even if 0 V is specified as the analog voltage ref-
erence. This happens if the host controller or external circuit has a slight offset (in the units of mV) in the refer-
ence voltage. Adjustments can be done manually or automatically by using the panel operator or digital operator.
Refer to 8.2 Operation in Utility Function Mode (Fnooo).
The automatic adjustment of the analog (speed, force) reference offset (Fn009) automatically measures the
amount of the offset and adjusts the reference voltage.
The SERVOPACK automatically adjusts the offset when the host controller or external circuit has the offset in
the reference voltage.
After completion of the automatic adjustment, the amount of offset is stored in the SERVOPACK. The amount of
offset can be checked in the speed reference offset manual adjustment mode (Fn00A).
