Hello everyone,

I am working on a configuration involving a CU320-2 PN from the SINAMICS S120 range, paired with a Double Motor Module equipped with the Safe Brake Control (SBC) function.

My question is as follows:

Is it possible to use the Safe Brake Test (SBT) function when the Safe Brake is managed by the SINAMICS system for two motors (with integrated brakes) mounted on the same drivetrain?

In this case, it would be necessary to disengage Motor 1 during the test on Motor 2, and vice versa.

I hope my question is clear enough.

Thank you in advance for your help!

Best regards.
