P3.7.7 RampTimeFactor
The Ramp time factor defines the acceleration/
deceleration time when the output frequency is in a
prohibited frequency range. The Ramp time factor is
multiplied with the value of parameters P3.4.1.2/
P3.4.1.3 (Ramp acceleration/deceleration time). For
example the value 0.1 makes the acceleration/
deceleration time ten times shorter.
