If this function, particularly manual servo tuning, 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 mm/s.
• Adjust the operator until the force reference monitor ripple is minimized by using the
analog monitor.
• Adjust the phase-U and phase-V offsets alternately several times until these offsets
are well balanced.
