The 1S-series Servo Drives Advance Type support 100-Mbps EtherCAT.
When you use the 1S-series Servo Drive Advance Type with a Machine Automation Controller
NJ/NX-series CPU Unit or CJ1W-NC□8□ Position Control Unit with EtherCAT interface, you can
construct a high-speed and sophisticated positioning control system.
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 tuning functions, adaptive notch filter, notch filter, and damping control, you can set up a system
that provides stable operation by suppressing vibration in low-rigidity machines.
The 1S-series Servo Drives Advance Type support the FSoE (Safety over EtherCAT) protocol as the
safety communications. You can build the safety system that uses safety functions from the safety
CPU unit on the EtherCAT network.
For further details on the 1S-series Servo Drives Advance Type, refer to the 1S-Series AC
Servomotors/Servo Drives with Built-in EtherCAT Communications and Safety Functionality User’s
Manual (Cat. No. I621).
