(2) Manual Adjustment of Reference Offset (Fn00B)
This mode adjusts the offset by inputting the amount of torque reference offset directly.
Use the manual adjustment of the torque reference offset (Fn00B) in the following cases:
• To deliberately set the offset amount to some value.
• To check the offset amount set in the automatic adjustment mode of reference offset.
Note: The adjusted value is not initialized by executing the Fn005 function (Initializing Parameter Settings).
Preparation
The following conditions must be met to adjust the offsets of torque reference manually.
• The write prohibited setting parameter (Fn010) must be set to Write permitted (P.0000).
• The main circuit power supply must be ON. (Refer to 5.10.4)
Operating Procedure
Adjust the reference offset manually with the digital operator using the following steps.
