5 Servo Adjustment

5.1 Servo Adjustment Procedure

Measures against the vibration
·
Notch filter
·
Jitter compensation
·
Variable speed loop gain
Mainly measure the position droop
waveform.
Measure the electrical end position
FB (encoder position FB) waveform.
CAUTION
Perform adjusting the servo in the factory configuration of the machine. When the servo is adjusted without having an
enough running-in or a cover, friction torque, machine resonance frequency or resonance gain may be different, resulting in
an incorrect adjustment.

Setup has completed.
Look for the maximum value not causes
machine resonance. The final setting
value should be 70 to 80% of the
maximum value at which the machine
does not resonate.
Perform the adjustment so that vibration or
overshooting does not occur.
Perform lost motion compensation
Set the functions of overload detection,
deceleration control at emergency stop,
vertical axis drop prevention, etc.
Accuracy adjustment of
the electrical end position FB has completed.
