Professional FAQ

• Q: Can this drive run a 75 kW motor at 415 V 50 Hz?A: Yes. Rated for 380‑480 V, 50/60 Hz. At 415 V, output current ~137 A, suitable for 75 kW.
• Q: What switching frequency should I set?A: Start with 2.5 kHz. For quieter motors, increase to 4‑8 kHz, but derate current above 2.5 kHz.
• Q: Do I need an external braking resistor?A: For high inertia loads (cranes, hoists), use a resistor for ≤150 % braking torque. Without resistor, torque is 30 %.
• Q: Can I use this with an old motor without encoder?A: Yes, sensorless flux vector (SFVC) works well. Speed accuracy ±10 % of slip, enough for most pumps/fans.
• Q: How to choose between open‑loop and closed‑loop?A: Use open‑loop for variable torque (pumps, fans). Use closed‑loop with encoder for constant torque and precise speed (±0.01 %).
