G5-series AC Servomotors and Servo Drives User’s Manual (with Built-in EtherCAT Communications)
1-1 Outline
The G5-series Servo Drives with Built-in EtherCAT Communications support 100-Mbps EtherCAT.
When you use the G5-series Servo Drive with a Machine Automation Controller NJ-series (Model:
NJ501-1
îš…00) or CJ1W-NCîš…8îš… EtherCAT-compatible Position Control Unit, you can construct 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.
G5-series Servo Drives have the following features.
As a Sysmac Device, you can use the G5-series AC Servo Drive (with Built-in EtherCAT
Communications) together with the NJ-series Machine Automation Controller and the Sysmac Studio
Automation Software to achieve optimum functionality and ease of operation.
* Sysmac Device is a generic term for OMRON control devices such as an EtherCAT Slave, designed with unified
communications specifications and user interface specifications.
Combining the G5-series Servo Drive with a Machine Automation Controller NJ-series (Model: NJ501-
1
îš…00) or CJ1W-NCîš…8îš… EtherCAT-compatible Position Control Unit enables you to exchange all
position information with the controller in 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.
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.
The 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.
