Frequently Asked Questions
- Q: What is the maximum output frequency?
A: 600 Hz – sufficient for high-speed spindle applications. - Q: Is the keypad included?
A: No, the keypad is sold separately (model VFD-KP+ or similar). - Q: Does it support dynamic braking?
A: Yes, an internal braking transistor is included; external resistor may be optional. - Q: Can I use this with a single-phase input?
A: No, it requires 3-phase input (380–480 VAC). - Q: What is the recommended storage temperature?
A: -20°C to +60°C, avoid condensation.
Experience-based Selection Guide
- For constant torque loads (conveyors, mixers) – choose this 5 HP model directly.
- For variable torque (fans, pumps) – you can also use, but consider derating.
- If you need advanced positioning – add the PG card for closed-loop feedback.
- Always size the drive at least 10% above motor FLA for longevity.
