3 Utility Function Mode
3.2.14 Manual Offset-Signal Adjustment of the Motor Current Detection Signal (Fn00F)
3.2.14 Manual Offset-Signal Adjustment of the Motor Current
Detection Signal (Fn00F)
Use this function only if the torque ripple is still high after the automatic offset-signal
adjustment of the motor current detection signal (Fn00E).
Note: Fn005 cannot initialize any value adjusted with Fn00F.
(1) Preparation
The following condition must be met to manually adjust the offset of the motor cur-
rent detection signal.
• The write prohibited setting (Fn010) must not be set to write-protect parameters.
(2) Operating Procedure

If this function is executed carelessly, it may worsen the char-
acteristics.
Observe the following precautions when performing manual
servo tuning.
• Run the servomotor at a speed of approximately
-1
100 min .
• Adjust the offset while monitoring the torque reference with
the analog monitor until the ripple of torque reference
monitor's waveform is minimized.
• Adjust the phase-U and phase-V offset amounts alter-
nately several times until these offsets are well balanced.
