P730/P733 Brake function1/2
1
2
Setting range: ON/OFF
Determines whether the brake is activated when the enable is revoked (enable="0").
In a hoist, the brake is always active in controlled operation.
P731/P734 Brake release time1/2
1
2
AUTO
Setting range: 0–2s
The brake release time of the matching motor is set as the factory setting.
Specifies how long the motor will remain at a standstill after expiration of the premag-
netization time and how much time the brake has to release.
P732/P735 Brake application time1/2
1
2
AUTO
Setting range: 0–2s
The brake application time of the matching motor is set as the factory setting.
Specifies the time required for the mechanical brake to apply. This parameter prevents
a sagging of the drive (particularly in hoists).
P74. Speed skip function
With these parameters, the motor speed can be prevented from persisting within a
certain speed window. This suppresses vibration and noise, in particular in machines
with pronounced mechanical resonance.
The parameters automatically have effect on positive and negative setpoints when ac-
tivated. In the factory setting, the function is deactivated (P741/P743 Skip width 1/2
=0).
