Activate brake immediately when pulse is inhibited
If bit 1 is set to "0" under C02582
(Lenze setting), the brake will be immediately applied
when the pulse is inhibited to avoid damage to the mechanical components.
Especially in the case of hoist drives, immediate engagement of the brake is absolutely
necessary for safety reasons if the pulse inhibit function of the drive controller has been
activated!
Only activate brake below threshold for brake activation
If bit 1 is set to "1" under C02582
, the brake will remain released until the lower speed
threshold is reached to avoid an excessive wear of the brake.
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.
During uncritical operation (horizontal loading condition), delayed brake application may
be required to protect the brake in case of high centrifugal masses.
The command for brake application depends on two conditions:
1. On the settings selected under C02582
, in particular:
– Bit 1 = response to pulse inhibit
– Bit 3 = direction of the axis
2. The signal of the rotary transducer which provides for the brake activation when the set
threshold has been fallen below.
