Professional FAQ – Practical & Selection Guide

• Q: Can this drive run a 5 HP motor continuously?
  A: Yes, with derating above 50 °C. For 5 HP (3.7 kW), reduce switching frequency to 4 kHz or ensure forced cooling. We recommend checking the motor nameplate FLA.
• Q: What is the difference between open-loop and closed-loop flux vector?
  A: Open-loop (SFVC) works without encoder – good for 95 % of applications. Closed-loop (FVC) requires an encoder and delivers ±0.01 % speed accuracy for hoisting or positioning.
• Q: How to wire the PTC probe input for motor thermal protection?
  A: Connect the PTC sensor to LI6 and set the switch to PTC position. The drive will trip on over-temperature – a simple and reliable protection.
• Q: Does this model support Safe Torque Off (STO)?
  A: Yes, the PWR input (ISO 13849-1 level d) provides STO function. Response time ≤ 100 ms – suitable for emergency stop circuits.
• Q: Which communication card should I choose for Profibus or EtherNet/IP?
  A: This drive accepts optional cards: Profibus DP V1, EtherNet/IP, DeviceNet, Modbus TCP, and more. Select based on your PLC network. We can advise on compatibility.
