Professional FAQ
- What is the maximum output frequency?
- 599 Hz – suitable for high-speed spindles.
- Does it support regenerative braking?
- Yes, the internal GTR7 transistor handles dynamic braking.
- Can I use it with single-phase input?
- No, it requires a 3-phase 400V supply.
- What is the ambient temperature limit?
- Operates up to 50 °C without derating.
- Is a separate output reactor needed?
- For motor cable longer than 50m, yes – recommended.
Selection Guide & Experience Tips
- Match motor FLA (Full Load Amps) to the 50A rating.
- For crane applications, add a braking resistor for heavy loads.
- Set switching frequency to 2 kHz for quiet motor operation.
- Use shielded cables for encoder feedback if installed.
- Always ground the drive properly to avoid EMI issues.
Warranty & Shipping
- 12-month warranty against manufacturing defects.
- 24-hour dispatch on business days.
- Express delivery via FedEx, UPS, or DHL – tracking included.
