(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:

Use the following procedure to manually adjust the torque reference offset.

Offset Adjustment Range: -

128 to +127

(Torque reference: -1881.6 mV to +1866.9 mV)
