P3.7.7 RAMP TIME FACTOR (ID 518)
Use this parameter to set the multiplier of the selected ramp times when the output
frequency of the drive is between the prohibited frequency limits.
The Ramp Time Factor sets the acceleration and the deceleration time when the output
frequency is in a prohibited frequency range. The value of the Ramp Time Factor is multiplied
with the value of P3.4.1.2 (Acceleration Time 1) or P3.4.1.3 (Deceleration Time 1). For
example, the value 0.1 makes the acceleration/deceleration time ten times shorter.
