8 Operation
8.7.3 Adjusting the Reference Offset
8-62
Use the following procedure for automatic adjustment of the torque reference offset.
(2) Manual Adjustment of the Torque Reference Offset
Manual adjustment of the torque reference offset (Fn00B) is used in the following cases.
• If a position loop is formed with the host controller and the error is zeroed when servolock is stopped.
• To deliberately set the offset to some value.
• Use this mode to check the offset data that was set in the automatic adjustment mode of the torque refer-
ence offset.
This mode operates in the same way as the automatic adjustment mode (Fn009), except that the amount of offset
is directly input during the adjustment.
The offset adjustment range and setting units are as follows:

Key Description
1 Turn OFF the SERVOPACK, and input the 0-V reference voltage
from the host controller or external circuit.
2 Press the DSPL/SET Key to select the utility function mode.
3 Press the LEFT/RIGHT or UP/DOWN Key, or UP or DOWN Key to
select parameter Fn009.
*The digit that can be set will blink.
4 Press the DATA/ENTER Key. “rEF_o” will be displayed.
5 Press the DSPL/SET Key.
The reference offset will be automatically adjusted.
When completed, “donE” will blink for about one second.

About one second
later
After “donE” is displayed, “rEF_o” will be displayed again.
7 Press the DATA/ENTER Key to return to the Fn009 display of the
utility function mode.
