Maximum of three consecutiv

energy stops with W

Holding torque M
4
: The holding torque M
4
is the highest permissible torque for the closed
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
1m
: The dynamic braking torque M
1m
is the smallest mean
dynamic braking torque that can occur for an EMERGENCY STOP.
Opening time t
o
and closing time t
cl
: The delay times that occur when switching the
brake t
o
and t
cl
are saved in the motor and are automatically taken into consideration. After
activation of the holding brake (opening), the speed/velocity setpoint remains at "Zero"
during the opening time t
o
. The speed/velocity setpoint is only enabled after the opening
time t
o
has elapsed. After OFF1 or OFF3 and activation of the holding brake (closing), the
motor still remains in closed-loop control with speed/velocity setpoint "Zero" during closing
time t
cl
. The pulses are only deleted after this.
Maximum permissible single operating energy W
max
: The maximum permissible single
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 threeminutes
before you operate the motor again.
Total operating energy (service life) W
total
: The total operating energy is the sum of the
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.
