Advanced vibration
suppression control
suppression control
This function suppresses vibration at the arm end or residual vibration.
Adaptive filter
Servo amplifier detects mechanical resonance and sets filter characteristics
automatically to suppress mechanical vibration.

Machine analyzer function
Analyzes the frequency characteristic of the mechanical system by simply
connecting MR Configurator installed personal computer and servo amplifier.
MR Configurator is necessary for this function.
Make sure to execute the machine analyzer function after the magnetic pole
detection. If the magnetic pole detection is not executed, this function may not
operate properly.

Robust disturbance
compensation
compensation
This function provides better disturbance response in case of low response level
due to high load inertia moment ratio for the roll send axis.
