Applicable Industries

Installation Requirements

1. Vertical mounting on 35 mm standard DIN rail inside high-voltage isolated sealed control cabinet
2. Mandatory ventilation clearance: 60 mm top exhaust gap, 40 mm bottom intake gap, 25 mm lateral gap between adjacent high-voltage drives
3. Cabinet high-temperature resistant forced cooling fan mandatory for continuous full-load operation above 30°C ambient temperature
4. All three-phase high-voltage power cables adopt shielded thick cross-section twisted pair, single-point cabinet ground bar shield connection
5. Strict separate routing channels for high-voltage power cables and low-voltage signal/encoder cables to avoid high-voltage electromagnetic noise interference
6. STO safety circuit wiring strictly follows official high-voltage safety schematic drawing

Usage Precautions

1. Forbidden exposed installation outside isolated high-voltage cabinet; conductive dust and humidity cause fatal high-voltage short-circuit hazard
2. Input three-phase voltage must stay within 187–528 VAC operating range; overvoltage permanently damages high-voltage IGBT power modules
3. Complete full-load motor auto-tuning procedure before formal production operation; mismatched motor parameters induce violent torque oscillation and overcurrent shutdown
4. Do not disconnect motor power cable while drive is energized; live disconnection generates high-voltage arc damage to power stage
5. Power supply must install three-phase EMC filter matching AKD-P01207 to comply with CE EMC electromagnetic compatibility standards
6. Quarterly heat sink fin and cooling fan dust cleaning mandatory in metal processing workshop environments to prevent overtemperature automatic shutdown
