Outline
The G5-series AC Servo Drives With Built-in EtherCAT Communications, Linear Motor Type supports
100 Mbps EtherCAT.
When you use the G5-series Servo Drive with a Machine Automation Controller NJ-series (Model:
NJ301-
/NJ501-
) or EtherCAT-compatible Position Control Unit (Model:
CJ1W-NC
8
), 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
*1
, the G5-series AC Servo Drives With Built-in EtherCAT Communications, Linear
Motor Type is designed to provide optimal functionality and ease of use when used in conjunction with a
Machine Automation Controller such as NJ-series and the automation software Sysmac Studio.
*1
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:
NJ301-
/NJ501-
) or EtherCAT-compatible Position Control Unit (Model:
CJ1W-NC
8
) 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.
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. Even during the torque (force) OFF status, the present
position of the motor is monitored by the control circuits to eliminate the need to perform an origin
search when restarting.
