Holding brake diagram
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 when at standstill and when perform‐
ing the drive-integrated brake check. The holding brake is required for hold‐
ing the axis when the machine is in a de-energized state.
