The OMNUC G Series AC Servo Drives (with built-in MECHATROLINK-II communications support) are a series of Servo Drives supporting the MECHATROLINK-II high-speed motion field network. When used with the MECHATROLINK-II Position Control Unit (CJ1W-NCF71 or CS1W-NCF71), a sophisticated positioning control system can be made easily with one communications cable connecting the Servo Drive and Controller. With realtime autotuning, adaptive filter, notch filter, and damping control, you can set up a system that provides stable operation by suppressing vibration in low-rigidity machines.
Data Transmission Using MECHATROLINK-II Communications
When used with the MECHATROLINK-II Position Control Unit (CJ1W-NCF71 or CS1W-NCF71), all control data between the Servo Drive and Controller can be exchanged through data communications.
Since the various control commands are transmitted via data communications, Servomotor‘s operational performance is maximized without being limited by interface specifications such as the response frequency of the encoder feedback pulses. This makes it possible to use the Servo Drive’s various control parameters and monitor data via a host controller, allowing you to unify the system data control.
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 vibration filters are provided to enable switching the vibration frequency automatically according to the direction of the rotation. Furthermore, the settings can be made easily by just 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 Suppression Control
The realtime autotuning function automatically estimates the load inertia of the machine in realtime and sets the optimal gain. The adaptive filter automatically suppresses vibration caused by resonance. Two independent notch filters make it possible to reduce the vibration of a mechanism with multiple resonance frequencies.
Command Control Mode Switching
Operations can be performed by switching between two of the following control modes: Position control, speed control, and torque control. Therefore, a variety of applications can be supported by one Servo Drive.
