Overview of the G Series
The OMNUC G Series has been developed for a wide range of applications with position control,
speed control, and torque control. The Series offers a wide variety of Servomotor capacities,
ranging from 50 W to 7.5 kW. Servomotors with 2,500-pulse incremental encoders and high-
resolution 17-bit absolute/incremental encoders are available as standard models.
The OMNUC G Series features realtime autotuning and adaptive filter functions that automatically
perform complicated gain adjustments. A notch filter can also be automatically set to suppress
machine vibration by reducing mechanical resonance during operation. The damping control
function of the OMNUC G Series realizes stable stopping performance in a mechanism which
vibrates because of the low rigidity of the load.
Features of the G Series
The OMNUC G Series has the following features.

High-speed Response
The G-Series AC Servomotors and Servo Drives have achieved high-speed response capabilities
exceeding OMRON’s W-Series models, with a high-response frequency of 1 kHz (compared to
400 Hz for the W Series).

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 rotation and also via an external signal. In addition, the
settings can be made easily merely 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. Also, two independent notch filters make it possible to reduce vibration of a mechanism
with multiple resonance frequencies.

Command Control Mode Switching
Operation can be performed by switching between two of the following control modes: Position
control, speed control (including internal speed) and torque control. Therefore, a variety of
applications can be supported by one Servo Drive.

Simplified Speed Control with Internal Speed Settings
Eight internal speed settings allow you to change the speed easily by using external signals.
