Switching energy - operating frequency - operating times
1)
The operating times specified refer to the usage of coils with a connection voltage of 24 V DC at s
LN
and 0.7 I
N
and
an induction voltage peak of 300 V.

, since it is a pure holding brake.
Engagement time
The transition from a brake-torque-free state to a holding-braking torque is not free of time lags.
For emergency braking, short engagement times for the brake are absolutely essential. Therefore, a circuit
without a freewheel branch with an induction voltage peak must be provided. The level of the limited in-
duction voltage is decisive for the engagement time of the brake.
Engagement time with freewheel diode: The engagement time is significantly longer (approx. 10 - 12 times
longer).
NOTICE
Connect the spark suppressors in parallel to the contact. If this is not admissible for safety
reasons (e.g. with hoists and lifts), the spark suppressor can also be connected in parallel
to the brake coil.
¾
The specified engagement times are valid for DC switching with a spark suppressor.
– Circuit proposals: refer to DC switching at mains – fast engagement.
Notice
Spark suppressors are available for the rated voltages.
Disengagement time
The disengagement time is the same for DC-side and AC-side switching. The disengagement time in-
creases as the wear increases. Refer to the specifications for the disengagement time at max. air gap.
