Outline of the OMNUC G5 Series

With the OMNUC G5 Series, you can perform fully-closed control in addition to position control,
speed control and torque control.
Various models are available supporting wide-ranging motor capacities from 50 W to 15 kW and
1
input power supplies from 100 to 400 V. You will surely find a model that best suits your application.
Motors with high-resolution 20-bit incremental encoders and 17-bit absolute/incremental
encoders are available as standard models.
The OMNUC G5 Series features realtime autotuning function and adaptive filter function that
automatically perform complicated gain adjustments. A notch filter can also be automatically
set to suppress machine vibration by reducing machine resonance during operation.
The damping control function of the Servomotor and Servo Drive realizes stable stopping
performance in a mechanism which vibrates because of the low rigidity of the load.

Features of OMNUC G5-series Servo Drives

OMNUC G5-series Servo Drives have the following features.
Switching between Seven Control Modes
You can switch between seven control modes: 1) Position Control Mode, 2) Speed Control
Mode, 3) Torque Control Mode, 4) Position and Speed Control Mode, 5) Position and Torque
Control Mode, 6) Speed and Torque Control Mode, and 7) Fully-closed Control Mode. Desired
modes can be selected with the flexible drive according to your need. A single drive supports
various applications.
Achievement of Accurate Positioning by Fully-closed Control
Feedbacks from the external encoder connected to the motor is used to accurately control positions.
Accordingly, position control is not affected by deviation caused by ball screws or temperature.
Wide Range of Power Supplies to Meet Any Need
The OMNUC G5 Series now has models supporting 400 V for use with large equipment, at
overseas facilities and in wide-ranging applications and environment. Since the utilization ratio
of facility equipment also increases, the TCO (total cost of ownership) will come down.
Safe Torque OFF (STO) Function to Ensure Safety
You can cut off the motor current to stop the motor based on a signal from an emergency stop
button or other safety equipment. This can be used for an emergency stop circuit that is
compliant with safety standards without using an external contactor.
Suppressing Vibration of Low-rigidity Mechanisms during Acceleration/Deceleration
The damping control function suppresses vibration of low-rigidity mechanisms or devices
whose tips tend to vibrate.
Two damping filters are provided to enable switching the damping frequency automatically
according to the rotation direction and also via an external signal. In addition, the settings can
be made easily by setting the damping frequency and filter values.
