Holding brake for 75 W motors
75 W motors do not have an integrated holding brake.
An external holding brake can always be used. In this case, it is
controlled using an appropriately parameterized digital output.
Holding brake for 300 W motors
300 W motors are optionally available with integrated holding brake.
An external holding brake can always be used. In this case, it is
controlled using an appropriately parameterized digital output.
It is not permissible to use the integrated holding brake as working
brake, as generally it is only designed for a limited number of
emergency braking operations.
Axial forces may not be applied to the shaft – both when installing
and operating the system!
