7.11 Manual Offset-Signal Adjustment of the Motor Current
Detection Signal (Fn00F)
Use this function only if the force ripple is still high after the automatic offset-signal adjustment of the motor
current detection signal (Fn00E).
Note: The adjusted value is not initialized by executing the Fn005 function (Initializing Parameter Settings).
(1) Preparation
The following condition must be met to manually adjust the offset of the motor current detection signal.
• The write prohibited setting parameter (Fn010) mu
st be set to Write permitted (P.0000).
(2) Operating Procedure
Use the following procedure.
If this function is adjusted incorrectly and then executed, characteristics of the servomo-
tor performance could be affected.
Observe the following precautions when performing manual servo tuning.
• Run the servomotor at a spe
ed of approximately 100 mm/s.
• Adjust the offset while monitoring the force reference with the analog monitor until the
ripple of force reference monitor's waveform is minimized.
• Adjust the phase-U and phase-V offset amounts alternately several times until these
offsets are well balanced.
