Applicable Industries

Installation Requirements

1. Vertical mounting on standard 35mm DIN rail; maintain 80mm minimum top/bottom ventilation clearance
2. Cabinet internal natural convection cooling mandatory; forced fan required for continuous operation above 45°C ambient temperature
3. Servo power cable minimum cross-section 1.5mm² copper wire; feedback cable must adopt double-shielded twisted pair dedicated servo wiring
4. Unified cabinet grounding connection, grounding resistance ≤4Ω, separate ground wire for drive power terminal and signal shield layer
5. Power wiring and signal wiring laid in independent cable troughs, minimum 10cm separation distance to avoid electromagnetic interference
6. Installation environment free of oil mist, metal dust and corrosive chemical gas; air filtration required for dusty workshop sites

Usage Precautions

1. Cut off main power and wait 5 minutes for DC bus capacitor full discharge before disassembling wiring terminals to prevent electric shock risk
2. Forbid motor three-phase output terminal short-circuit when drive powered on, instantaneous short-circuit destroys internal IGBT power module
3. Avoid continuous operation under condensation environment; moisture infiltration causes PCB short-circuit and insulation damage
4. Do not install near high-vibration equipment; long-term vibration loosens internal terminal wiring and solder joints
5. Conduct semi-annual dust cleaning on aluminum heat sink fins; accumulated dust causes over-temperature shutdown protection
6. RS232 configuration cable must be disconnected after parameter commissioning to avoid external electromagnetic signal interference to motion control
