Applicable Industries

Installation Requirements

1. Vertical installation on standard 35mm DIN rail inside sealed electrical cabinet; maintain 100mm minimum top/bottom ventilation clearance, 20mm left-right gap between adjacent servo drives
2. Cabinet forced cooling fan mandatory for continuous operation above 40°C ambient temperature; airflow direction parallel to heat sink fin arrangement
3. Motor power cable minimum cross-section 1.5mm² copper wire; feedback signal cable must adopt double-shielded twisted pair dedicated servo cable
4. Drive grounding terminal connected to cabinet unified ground bar, grounding resistance ≤4Ω, grounding wire cross-section ≥4mm²
5. Strong power wiring and weak signal wiring laid in separate cable troughs, minimum 15cm separation distance to avoid electromagnetic coupling interference
6. Installation environment strictly isolated from metal dust, corrosive gas, oil mist and water vapor; air filter installed at cabinet air intake

Usage Precautions

1. Input mains voltage fluctuation must be controlled within ±10% rated voltage; excessive voltage deviation causes permanent overvoltage damage to internal power components
2. Disconnect main power supply and wait 10 minutes for DC bus capacitor full discharge before disassembling wiring terminals to prevent high-voltage electric shock hazard
3. Strictly prohibit short-circuit of motor three-phase output terminals when the drive is powered on; instantaneous short-circuit will break down internal IGBT power modules
4. Forbid long-term operation under condensation environment; moisture infiltration leads to PCB short-circuit and insulation breakdown
5. Avoid installation near strong vibration sources such as stamping machines; continuous vibration loosens internal solder joints and terminal wiring
6. Conduct annual full cleaning of heat sink surface dust accumulation; blocked cooling fins trigger over-temperature protection and automatic equipment shutdown
7. STO safety circuit wiring must use independent dual twisted shielded cables, cannot share wiring channels with other digital signal lines
