Main Functions

1. Full servo motion control
    
   Support speed loop, torque loop and absolute positioning control; built-in electronic cam, flying shear, positioning table and other standard motion functions to realize micron-level accurate axis positioning.
2. Multi-network industrial communication
    
   Exchange real-time motion commands, status data and fault signals with S7-1200/S7-1500 PLC via PROFINET IO; support isochronous cycle for synchronous motion coordination.
3. Safety integrated control
    
   Equipped with failsafe I/O terminals to connect safety door, emergency stop signals, implement STO safe torque off function without extra safety relay.
4. Multi-channel signal collection & output
    
   Receive external limit switches, proximity sensors and analog setpoint signals; output digital signals to control valves, indicators and auxiliary relays.
5. Complete drive diagnosis
    
   Real-time monitor motor temperature, encoder fault, overcurrent, overload and communication errors; display fault codes on local LCD and upload alarm information to PLC/HMI.
6. Convenient commissioning
    
   Support parameter configuration, trace debugging and firmware upgrade via TIA Portal or STARTER drive software through RS232 or PROFINET port.
