Technical specifications of the brake for encoders for functional safety

The guide values for switching times required for rated operation of the holding brake can be
found in Catalog D50.1 (Chapter 11). These switching times may change as a result of actual
operating conditions and must then be adjusted accordingly.
NOTICE
Air gap check
Air gap check by operator only possible with force-ventilated motors.
