5.3.2 Reference Offset Adjustment
5-20
(2) Manual Adjustment of Reference Offset (Fn00A)
This method adjusts the offset inputting the amount of reference offset directly.
Use the manual adjustment of the reference offset (Fn00A) in the following cases:
• To adjust the position error to zero when a position loop is formed with the host controller and the servomo-
tor is stopped by servolock.
• 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 speed 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.
Step Display after Operation Keys Operation
1 Set the analog voltage input to 0 V.
2
Press the Key to view the main menu of the utility
function mode. Use the or Key to move
through the list and select Fn00A.
3
Press the Key. The display changes to the Fn00A
execution display.
4 Turn ON the servo ON (/S-ON) signal.
5 or
Press the or Key to adjust the reference speed
offset value.
6
Press the Key to write the speed reference offset
value into the SERVOPACK.
When the writing is completed, the status display shows
“DONE” for one second.
7
Press the Key.
The display returns to the main menu of the utility function
mode.
