6.16 Adjusting the Motor Current Detection Signal Offset
6.16.2 Manual Adjustment
6-104
6.16.2
Manual Adjustment
You can use this function if you automatically adjust the motor current detection signal offset
and the torque ripple is still too large.
Preparations
Always check the following before you manually adjust the motor current detection signal off-
set.
•
The parameters must not be write prohibited.
Applicable Tools
The following table lists the tools that you can use to manually adjust the offset and the applica-
ble tool functions.
Operating Procedure
Use the following procedure to manually adjust the motor current detection signal offset.
1.
Operate the motor at approximately 100 min
-1
.
2.
Click the
Servo Drive Button in the workspace of the Main Window of the S.
3.
Select
Adjust the Motor Current Detection Signal Offsets
in the Menu Dialog Box.
The Adjust the Motor Current Detection Signal Offsets Dialog Box will be displayed.
4.
Click the
Continue
Button.
If the offset is incorrectly adjusted with this function, the Servomotor characteristics may be
adversely affected.
Observe the following precautions when you manually adjust the offset.
•
Operate the Servomotor at a speed of approximately 100 min
-1
.
•
Adjust the offset while monitoring the torque reference with the analog monitor until the ripple is
minimized.
•
Adjust the offsets for the phase-U current and phase-V current of the Servomotor so that they
are balanced. Alternately adjust both offsets several times.
The offset does not use a parameter, so it will not change even if the parameter settings are
initialized.
