FAQ

1. Can this model run both synchronous and asynchronous motors?
Yes. It offers sensorless vector modes for both motor types.
2. What is your most common field feedback about this drive?
Users report stable torque at low speed and very low trip rates.
3. Is braking hardware required externally?
No. The unit includes an integrated brake chopper.
4. Does it support fast machine cycles?
Yes. High-speed I/O and fast analog response make it suitable for rapid processes.
5. What is the typical lifespan of the cooling fan?
Customers usually replace it after 3–5 years depending on duty cycle and ambient dust.
