13.3 Permissible braking frequency
The braking frequency depends on the adjusted braking current.
Please find below some typical values for braking devices of the VersiBrake type:
For intermediate values please refer to the load curve below.
Warning:
When setting up the machine or during commissioning it is possible to carry
out 10 braking operations in succession with the rated device current at a
braking time of 15s. After these operating conditions, however, the device
needs a recovery time of 20 minutes.
