Holding torque M
brake in steady-state operation without slip (holding function when motor is at standstill).
The data applies to the state at operating temperature (120 °C).
Dynamic braking torque M
dynamic braking torque that can occur for an EMERGENCY STOP.
Opening time t
brake t
activation of the holding brake (opening), the speed/velocity setpoint remains at "Zero"
during the opening time t
time t
motor still remains in closed-loop control with speed/velocity setpoint "Zero" during closing

Maximum permissible single operating energy W
operating energy of an individual EMERGENCY STOP operation. After an EMERGENCY STOP
with the maximum single operating energy, allow a cooling time of at least three minutes
before you operate the motor again.
Total operating energy (service life) W
single operating energy (operating energy for each EMERGENCY STOP procedure). If you
exceed the total operating energy, problem-free functioning of the brake can no longer be
guaranteed.
