The F6 VFD and S6 servo drive now support the Modbus TCP/IP communication protocol. In addition to Modbus TCP/IP, the other supported Ethernet-based network communication protocols include EtherNet/IP, EtherCAT, Profinet and Powerlink. The F6 and S6 drive controllers are equipped with safe torque off (STO) and are designed for speed and position control. They control both induction and ac permanent magnet servo motors. The two drives feature flexible heatsinks, a dual-channel encoder card, power ranges up to 400 hp and internal positioning capability for motion control applications.
