High-speed Response.
The G-series AC Servomotors and Servo Drives have,
achieved high-speed response capabilities, with a high,
response frequency of 1 kHz.
Suppressing Vibration of Low-rigidity Mechanisms during,
Acceleration/Deceleration.
The damping control function suppresses vibration of,
low-rigidity mechanisms or devices whose ends tend to,
vibrate. Two damping filters are provided to enable switching,
the vibration frequency automatically according to the direction,
of rotation and also via an external signal. In addition,
the settings can be made easily merely by setting the vibration,
frequency and filter values, and you are assured of stable,
operation even if the settings are inappropriate.
High-speed Positioning via Resonance Suppresssion Control,
The realtime autotuning function automatically estimates,
the load inertia of the machine in realtime and sets the,
optimal gain R88D-KN20F-ECT-L Calibration Parameter Manual. The adaptive filter automatically suppresses,
vibrationn caused by resonance R88D-KN20F-ECT-L Calibration Parameter Manual. Also, two independent,
notch filters make it possible to reduce vibration of a,
mechanism with multiple resonance frequencies.
