It denes the minimum value of the output of the ramp reference block, regardless of the signal that is present. The ramp
block output remains at the value set with this parameter until the analog signal exceeds this threshold: the ramp output
value then starts to follow the reference up to the value set in parameter PAR 634 Rampreftoplim. The limit is valid for
both directions of rotation.

In a system comprising a drive and motor, vibrations may be generated at certain frequencies, due to mechanical
resonance. This phenomenon can be limited by entering a prohibited speed at which the drive cannot operate

Example:
A) Increase in the reference by values of less than Par. 630
Par. 630 = 300 rpm (prohibited speed threshold)
Par. 632 = 10 rpm (thus prohibited band: 290rpm.310rpm)
Set speed reference = 295 rpmHz
Output speed = 290 rpm
Set speed reference = 305 rpm
Output speed = 290 rpm
