Core Functions

1. Three-loop digital closed-loop positioning control cooperating with host servo power stage: full current/speed/position closed-loop regulation for single servo axis

2. Dual operation mode:

   • Network Mode: Receive real-time position/speed instructions from upper master via SERCOS fiber bus to realize multi-axis synchronous linkage

   • Standalone Mode: Execute pre-stored point-to-point positioning, electronic gearing, sequential cam motion programs saved in onboard SRAM without external host command

3. Complete axis homing function: multiple home search modes including switch-reference marker homing, absolute encoder direct referencing per V15 firmware algorithm

4. Real-time drive fault detection & coded alarm output, programmable fault stop logic for overcurrent, encoder loss, overheat protection linkage

5. Adjustable electromagnetic holding brake delay control, automatic brake open/close logic matching motor positioning status

6. Parameter backup via onboard lithium battery, avoid configuration loss after servo main power cut-off

Application Scenarios
