Outline of the OMNUC G5 Series

The OMNUC G5-series Servo Drives with Built-in EtherCAT Communications support 100-
Mbps EtherCAT.
When you use the Servo Drive with a Position Control Unit with EtherCAT interface (CJ1W-
1
NC@81), you can create a sophisticated positioning control system. Also, you need only one
communications cable to connect the Servo Drive and the Controller. Therefore, you can
realize a position control system easily with reduced wiring effort.
With real time 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.

Features of OMNUC G5-series Servo Drives

OMNUC G5-series Servo Drives have the following features.
Data Transmission Using EtherCAT Communications
When you use it with a Position Control Unit with EtherCAT interface (CJ1W-NC@81), you can
exchange all control data between the Servo Drive and the Controller through high-speed 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.
You can use the Servo Drive's various control parameters and monitor data on a host
controller, and unify the system data for management.
Achievement of Accurate Positioning by Fully-closed Control
Feedback from the external encoder connected to the motor is used to accurately control
positioning. Position control is not affected by deviations caused by ball screws or temperature
changes.
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. In addition to the conventional stop method based on a
control signal, the STO function, which permits direct stopping without a need to involve the
control circuits, provides an emergency stop from 2 systems, thereby enhancing safety.
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.
