The holding brake should not be used to stop the turning motor during normal
operation! The holding brake should not be used for safety-relevant purposes
either.
Holding brakes are available as an option. The supplied holding
brake has been adapted to the corresponding motor!
Safety requirements
In normal operation, use the brake only in standstill and for performing the
drive-integrated brake test. The holding brake is required for holding the axis
when the machine is in a de-energized state.
