Working Principle
Upper master controller sends motion target position, speed and interpolation parameters via CANopen/Ethernet bus to INFO-4KP module internal dedicated motion CPU. The module outputs pulse direction control signal to servo drive, simultaneously collects real-time position feedback from servo encoder. Internal closed-loop algorithm compares target position and actual feedback value, dynamically adjust pulse output frequency to eliminate positioning error. Digital I/O terminals collect limit switch and sensor signals to trigger motion stop and interlock protection logic.
Material & Structural Characteristics
- Housing: Black ABS flame-retardant plastic integrated shell, ventilation slot for internal chip heat dissipation
- Wiring Terminals: Two groups of green pluggable screw terminal blocks, separate X1 power communication and X2 motion I/O wiring area
- Main Circuit Board: Multi-layer PCB with conformal coating, dedicated FPGA motion processing chip, differential signal transceiver
- DIN Rail Buckle: Integrated plastic metal clip, anti-vibration fixed structure
Installation Requirements
- Snap onto standard 35mm DIN rail inside automation equipment control cabinet, reserve 20mm upper and lower heat dissipation gap
- 24VDC power supply wiring uses shielded twisted pair cable, separate from servo power high-current wiring
- Encoder feedback cable adopts differential shielded cable, shielding layer single-end grounding at module terminal
- Field bus communication cable follows CANopen standard wiring specification, install terminal matching resistance at bus two ends
- Avoid installing adjacent to servo drives and frequency converters to reduce differential signal interference
Application Scenarios
- Laser cutting multi-axis linkage motion control system
- Printed circuit board high-speed drilling positioning equipment
- Packaging machinery multi-axis synchronous film feeding, cutting and sealing control
- Textile high-speed warp knitting machine electronic cam motion system
- Automobile precision parts CNC grinding fixture positioning control
Operation & Maintenance Precautions
- Do not hot plug encoder and servo signal terminals during equipment operation, which will cause axis runaway
- Regularly check bus terminal matching resistance; missing resistance leads to communication packet loss
- Set soft limit parameters within mechanical travel range to avoid hard limit collision damage to equipment
- Storage must use anti-static packaging; static electricity will damage internal motion FPGA chip
- Ambient condensation environment needs cabinet heating strip to prevent circuit board short circuit
