Does this model support an external braking resistor?

Answer This Question

Except for the spindle motor for CNC lathe, almost 99% of other equipment do not need automatic resistance. We can achieve it through automatic parameters. Because most of your application inertia is not large, you can achieve parking through parameters. You can tell me what kind of equipment you have, and we will configure the required parameters for you.

I'd like to use this to convert 240V single phase to 240V 3 phase on a fan that has a magnetic starter system. Will this work?

Answer This Question

Yes, but it is possible that the magnetic switch will not open. However, we have a way. When we start the inverter, we can use parameters to control the switch to disconnect the magnetic lines, so that it can be started.
