Frequently Asked Questions

What does the Safe Standstill function do?

It prevents unexpected motor starts. It safely removes power so maintenance can be done without risk.

What power supply do I need?

You need a three-phase power supply between 320V and 528V, with a frequency of 45-65 Hz.

Why are there two switching frequencies?

The 8 kHz setting gives you higher output current. The 16 kHz setting makes the motor run smoother and quieter.

Can it handle sudden high load demands?

Yes. It can provide 50% more current for one minute, and double the current for 10 seconds when needed.

Is special mounting required?

Due to its 59 kg weight, ensure your mounting surface is strong and secure. Use proper equipment for handling.
