Spring-applied brakes
NOTICE
If used as a service brake, the braking torques are dependent on the motor speed to be
braked.
▶
During braking from a high speed and in the event of emergency stops, the braking torque is
signicantly reduced.
LongLife version
The applicaon brake is available in a LongLife version for applicaons with very high
switching frequencies. The standard design has a guaranteed service life for the brake
mechanism of 1 million switching cycles.
The LongLife version has a reinforced brake mechanism and up to 10 million repeang or 15
million reversing switching cycles possible.
Reducon of the holding current (cold brake)
By reducing the holding current, the half-wave bridge recer reduces the power input of the
released brake. As the brake heats up less, this type of control is known as "cold brake". This is
necessary at low speeds to counteract any impermissible heang up. This means that no
blower is needed at a speed seng range under 14 Hz. Addionally, only one quarter of the
braking power is required, thus saving energy.
Short-me overexcitaon of the brake coil
The disengagement me can be reduced by triggering the brake coil with twice the rated
voltage for an overexcitaon me. The brake releases much faster and the wear on the
fricon lining decreases. As a result of these features, this control variant is parcularly ideal
for liing applicaons.
