7.11 Manual Offset-Signal Adjustment of the Motor Current Detection (Fn00F)
If this function is executed carelessly, it may worsen the characteristics.
Observe the following precautions when performing manual servo tuning.
• Run the servomotor at a speed of approximately 100 min
• Adjust the offset until the torque reference monitor ripple is minimized, monitoring the
torque reference by using the analog monitor.
• Adjust the phase-U and phase-V offsets alternately several times until these offsets
are well balanced.
