Explanation of the parameters
Parameters
P731/P734 Brake
release time 1/2
Setting range: 0 ... 0.1 ... 2 s
This parameter determines how long the motor will remain at a standstill after expiration
of the premagnetizing time and how much time the brake has to release.
P732/P735 Brake
application time
1/2
Setting range: 0 ... 0.1 ... 2 s
Serves to set the time required for application of the mechanical brake. This parameter
prevents a sagging of the drive (particularly in hoists).
P74x Speed skip
function
The skip window center and skip width are values and automatically have an effect on
positive and negative setpoints when activated. The function is deactivated by setting
the skip width to 0.
The 'Speed skip' function makes it possible to prevent the motor speed from remaining
within a certain speed window. This suppresses vibration and noise, in particular in ma-
chines with pronounced mechanical resonance.
P740 / P742 Skip
window center 1/2
Setting range: 0 ... 1500 ... 5000 1/min
P741 / P743 Skip
width 1/2
Setting range: 0 ... 300 1/min
