What is a Free-Run Stop?

What is a Free-Run Stop? It sounds like motor freewheeling. Are there differences between free-run stop and freewheeling?

Free-run stopping is a method of stopping a motor. It happens when the motor drive simply turns OFF its motor output connections. This allows the motor and load to coast to a stop. A mechanical brake may also be engaged to shorten the deceleration time. It is the same as freewheeling I guess.

Yes or no to Free Run Stop? Inertia and stopping time is obviously the most critical aspect here.

The time it takes for an electric motor to come to a stop naturally depends on factors such as the inertia of the load, the motor size, and the operating conditions. In some cases, allowing the motor to stop freely may be acceptable if the stopping time is within safe limits.

Your brake will never fail if you don't use a brake at all. So it is a nice option if it is practical and safe.
