Working Principle
24VDC auxiliary power energizes module internal logic and analog signal processing circuits. Digital position pulse commands transmitted from upper motion controller enter isolated digital input channel, converted via internal D/A conversion circuit into proportional ±10VDC differential analog speed command signal, output to PRD analog servo amplifier speed reference terminal. Motor tachometer analog voltage or quadrature encoder digital pulse feedback signal from servo motor enters dedicated conditioning circuit, filtered and amplified to standardized signal level, then transmitted back to host motion controller for closed-loop position deviation calculation. Built-in transient voltage suppression components clamp abnormal overvoltage surge signals instantly to protect internal operational amplifier and digital logic chips from permanent breakdown. On-board temperature sensor triggers fault indicator light and signal lockout once PCB temperature exceeds 75°C threshold.

Applicable Industries
Legacy analog textile looms, vintage printing press equipment, old generation packaging automation lines, laboratory analog motion test benches, traditional machine tool servo axis transformation and upgrade projects, low-speed positioning analog control production equipment
Installation Requirements
- Slide module fully into standard 3U cabinet rack rail, lock front panel fixing screws with tightening torque of 0.8 N·m
- Maintain minimum 10mm horizontal clearance between adjacent rack modules for cross-module heat dissipation
- 24VDC auxiliary power wire connected to dedicated power terminal with 1.0mm² copper conductor, single-point chassis grounding
- Analog servo command wiring and digital feedback wiring separated into different rack cable channels with minimum 10mm spacing
- All shielded signal cable shielding layers single-point grounded at module terminal side only to avoid ground loop noise
Operation Precautions
- Continuous operation above +50°C cabinet ambient temperature requires 20% reduction of signal output load driving capacity
- Disconnect 24VDC auxiliary power supply before all terminal wiring modification or signal circuit maintenance
- Do not apply input signal voltage exceeding ±12VDC to analog feedback terminals to avoid permanent operational amplifier damage
- Regularly clean front terminal block dust accumulation every 1000 operating hours to prevent signal contact resistance rise
- Module must not be operated outside closed IP20 rack cabinet; open-air installation causes dust ingress and signal circuit short-circuit fault
- Fault lockout state triggered by over-temperature can only be cleared by complete 24VDC power cycle restart; signal reset command cannot release lockout state
