Professional FAQ – Experience & Selection Guide

• Q: Can I use this drive with an older 380 V motor?
  A: Yes. Input range 380-480 V -15/+10 % covers most industrial motors. Check motor nameplate for voltage compatibility.
• Q: What is the real-world current capacity at 480 V?
  A: At 480 V, line current is 85 A and output current is 77 A (2.5 kHz). Useful for derating calculations in high-line applications.
• Q: How do I select the correct braking resistor?
  A: Use the <150 % torque rating. For hoisting or frequent stops, choose a resistor with thermal capacity matching duty cycle. Consult Schneider sizing tool.
• Q: Can this drive run a permanent magnet synchronous motor?
  A: Yes. Supports vector control without speed feedback for synchronous motors. Requires auto-tuning during initial setup.
• Q: What option card is best for Profibus DP integration?
  A: Use the VW3A3307 Profibus DP card. Supports cyclic I/O and parameter access. Ensure firmware version ≥ V5.3.
