Applicable Industries

Installation Requirements

1. Mount vertically on solid steel backplate inside IP20 rated control cabinet; horizontal mounting prohibited
2. Maintain minimum 100 mm vertical clearance above cooling fan outlet and 50 mm clearance below unit intake filter
3. Separate high-power motor cable wiring from low-voltage control signal wiring by minimum 30 cm distance
4. Install matched dynamic braking resistor when operating frequent fast deceleration duty cycles
5. Connect shielded motor cable with 360° metal gland shielding termination at drive cabinet wall

Usage Precautions

1. Replace cooling fan and filter mesh every 2 calendar years to prevent heat sink overheating faults
2. Derate output power capacity by 1% per °C ambient temperature above +40 °C
3. Do not operate drive without connecting motor thermal overload protection thermistor input for high-load applications
4. Avoid rapid cycling of mains input power supply within 60-second intervals to prevent DC bus capacitor degradation
5. Complete motor auto-tuning with motor uncoupled from mechanical load for accurate vector control performance
