Behaviour at pulse inhibit
In case of pulse inhibit the brake is applied. This occurs according to the parameter setting
either immediately (default setting) or delayed when the threshold set for brake
activation is fallen below, which can be selected to protect the brake if high centrifugal
masses occur.
Activate the brake in any case
When setting
= "0", the brake is triggered to close to prevent the mechanics from
being damaged.
Only activate the brake below the threshold set for brake activation
When
= "1", the brake remains released until the threshold set in
for brake
activation has been reached to protect the brake from excessive wear.
r
Braking is exclusively executed by the friction of the load mechanics.
r
Only when the motor speed has reached the threshold for brake activation, the brake
will be closed.
Note!
Pulse inhibit can be set in the enabled controller e.g. due to a DC overvoltage
during brake operation by a wrong dimensioning of the brake resistor.
Stop!
Do not set the threshold for brake activation in
too high to protect the
brake from wear.
