12.12.5.1 Behaviour in case of pulse inhibit
In case of pulse inhibit the brake is applied. This occurs according to the parameter setting in
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
= "0", the brake is immediately triggered to close to prevent the mechanics from
being damaged.
Note!
Setting the pulse inhibit results causes the motor to coast down in a load-controlled
manner until pulse enable is carried out again.
Pulse inhibit can be set in the enabled controller, e.g. due to a DC overvoltage, DC
undervoltage or the "Safe torque off" request.
Stop!
Before setting the parameters of
it is important to assess the energy conditions
of the machine.
The amount of energy stored in the machine can exceed the permissible switching
energy of a motor holding brake at the time of pulse inhibit and can thus destroy the
brake when being applied!
