3.2.10 Manual Servo-tuning of Torque Reference Offset (Fn00B)
This function executes the manual adjustment or the torque reference offset value.
Use this function in the following cases.
• To deliberately set the offset amount to some value.
• To check the offset amount calculated in the automatic adjustment mode.
(1) Preparation
The following conditions must be met to adjust the offsets of torque reference manu-
ally.
• The write prohibited setting (Fn010) must not be set to write-protect parameters.
• The main circuit power supply must be ON.
• All alarms must be cleared.
• The hardwire baseblock (HWBB) must be disabled.
• When an absolute encoder is used, the SEN signal is ON (high level).
(2) Operating Procedure
Use the following procedure.
