Only activate brake below threshold for brake activation
When C02582
= "1", the brake remains released until the threshold set in C02581 for brake
activation has been reached to protect the brake from excessive wear.
The braking action only takes places due to the friction in the load mechanics.
Only when the motor speed has reached the threshold for brake activation, the brake will be
closed.
Stop!
Do not set the threshold for brake activation in C02581 too high to protect the motor
holding brake from wear!
Note!
For the encoderless motor control types (from software version V3.0) the following
applies:
If V/f control without encoder or sensorless vector control is selected, there is no speed
information for the controller in the case of pulse inhibit, therefore the threshold set in
C02581
for the brake activation is not effective in this case.
In order to avoid that the motor holding brake is closed in case of pulse inhibit, a waiting
time for the brake activation can be parameterised in C02593
. In case of pulse inhibit,
the motor holding brake is then only triggered to close after this application time has
elapsed. Brake activation in automatic operation
