EtherCAT-compatible Position Control Unit, you can construct a high-speed and
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 auto tuning, adaptive filter, notch filter, and damping control, you can set up a system that provides
stable operation by suppressing vibration in low-rigidity machines.
The FSoE protocol, the technology for a safe communication layer supported by the 1S-series Servo
Drives, allows you to build the safety system that uses the STO function from the safety controller on the
EtherCAT network.
