Applicable Industries

Installation Requirements

1. Vertical mounting on standard 35 mm DIN rail inside isolated sealed high-voltage control cabinet
2. Mandatory ventilation clearance: 60 mm top exhaust gap, 40 mm bottom intake gap, 25 mm lateral separation gap between adjacent high-voltage servo drives
3. Cabinet high-temperature resistant forced cooling fan mandatory for continuous full-load operation at ambient temperature above 30°C
4. All three-phase high-voltage power cables adopt thick cross-section shielded twisted pair cables with single-point shield grounding at cabinet earth bar
5. Strictly separate wiring channels for high-voltage power cables and low-voltage encoder/signal cables to block high-voltage electromagnetic noise induction
6. STO safety circuit wiring must strictly follow official high-voltage safety schematic drawings; unapproved wiring voids SIL2 safety certification

Usage Precautions

1. Forbid exposed installation outside isolated high-voltage cabinet; conductive dust and humidity create fatal high-voltage short-circuit hazards
2. Maintain three-phase input voltage strictly within 187–528 VAC operating range; sustained overvoltage permanently damages internal high-voltage IGBT power modules
3. Execute full-load motor auto-tuning procedure before formal production operation; mismatched motor parameters trigger violent torque oscillation and overcurrent shutdown protection
4. Never disconnect motor power cable while drive remains energized; live disconnection generates high-voltage electric arcs that burn power stage terminal pins
5. Install matched three-phase EMC filter on input power supply to fully comply with CE EMC electromagnetic compatibility standards
6. Clean heat sink fins and cooling fan dust accumulation every 3 months in metal processing workshops to prevent automatic overtemperature shutdown protection
