Frequently Asked Questions (FAQ)

Q: What is the main advantage of FOC in this drive?

• A: FOC provides superior control accuracy. It allows the drive to perform like a servo system. This includes precise speed regulation and accurate position control.

Q: Does this drive include a braking resistor?

• A: No. The drive supports dynamic braking, but the braking transistor is optional and external. You must purchase and connect a suitable external braking resistor separately.

Q: Can I use this drive for simple speed control without an encoder?

• A: Yes. While it excels in closed-loop vector control with an encoder, it can also operate effectively in open-loop modes for standard variable speed applications.
