Frequently Asked Questions

What's the difference between 8 kHz and 16 kHz operation?

8 kHz provides higher continuous output current for maximum power. 16 kHz offers smoother motor performance and quieter operation, ideal for high-precision tasks.

Can it run on DC power?

Yes. It has an alternative DC supply input range of 460-740 VDC, offering flexibility for different power system setups.

What size motor can this inverter drive?

It is perfectly matched to drive a standard 4-pole asynchronous servo motor (ASM) rated at 55 kW, which is approximately 75 horsepower.

Is the weight a concern for installation?

At 59 kg, it's a solid unit designed for industrial durability. Ensure your mounting structure and handling equipment are rated for this weight.

Why choose a 480V configuration?

The 480V setup offers higher output power (87.8 kVA) and peak current, making it more efficient for larger systems and reducing overall current draw.
