Main Functions

1. Full single-axis servo motion control
    
   Supports vector control, sensorless vector control and high-precision closed-loop servo control; built-in electronic cam, flying shear, positioning table and synchronous gearing functions for high-speed positioning tasks.
2. Real-time industrial network communication
    
   Exchange motion commands, actual position, speed and fault data with S7-1200 / S7-1500 PLC via PROFINET IRT, realizing synchronized multi-axis coordination.
3. Universal encoder signal processing
    
   Directly read DRIVE-CLiQ motor encoders; expandable to TTL, HTL, SSI external encoders via SMC modules for various positioning feedback demands.
4. Integrated machine safety control
    
   Hardware STO safe torque off function and PROFIsafe communication, safely cut motor torque without external safety relays, complying with international machinery safety standards.
5. Comprehensive channel & drive diagnosis
    
   Real-time monitoring of overcurrent, overvoltage, overload, overheat, encoder failure, wire break and communication loss; fault codes displayed locally and uploaded to PLC/HMI.
6. Flexible on-site commissioning
    
   Support parameter configuration, motion trace debugging and firmware upgrade through TIA Portal or STARTER software; BOP20 panel enables quick parameter modification without laptop.
