Applicable Industries

Installation Requirements

1. Vertical mounting on standard 35mm DIN rail inside sealed electrical cabinet; maintain 120mm minimum top ventilation clearance, 50mm bottom clearance for cooling fan airflow
2. Cabinet forced ventilation system mandatory for continuous 24-hour full-load operation above 40°C ambient temperature
3. Three-phase power input cable cross-section ≥4mm² copper wire; servo motor power cable minimum cross-section 2.5mm² copper conductor
4. Equipment unified grounding bar connection, grounding resistance ≤4Ω; power shield layer and signal cable shield layer single-end grounded at drive terminal side only
5. Strong power wiring and weak signal wiring separated into independent cable troughs, minimum 20cm separation distance to suppress electromagnetic coupling interference
6. Installation environment strictly isolated from conductive metal dust, corrosive chemical gas and water vapor; air intake filter screen installed at cabinet air inlet

Usage Precautions

1. Disconnect three-phase main power supply and wait 15 minutes for high-voltage DC bus capacitor full discharge before disassembling wiring terminals to prevent lethal electric shock hazard
2. Forbid direct short-circuit of motor three-phase output terminals under powered state; instantaneous short-circuit causes permanent breakdown of internal IGBT power module
3. Regular monthly cleaning of rear cooling fan dust filter screen; blocked filter causes heat sink over-temperature protection and equipment production shutdown
4. Prohibit operation under condensation environment; moisture infiltration leads to high-voltage PCB insulation breakdown and short-circuit fire risk
5. Avoid installation near strong vibration sources (hydraulic stamping equipment, large metal cutting machine tools); long-term vibration loosens heavy-duty power terminal wiring
6. DC bus parallel connection between multiple S60300-590 drives must use dedicated DC bus equalization cables per official wiring specification to eliminate current imbalance
7. External regenerative braking resistor wiring must adopt high-temperature resistant wire with over-temperature thermal fuse installed in series per rated power matching
