P3.7.7 RAMP TIME FACTOR (ID 518)Use this parameter to set the multiplier of the selected ramp times when the outputfrequency of the drive is between the prohibited frequency limits.The Ramp Time Factor sets the acceleration and the deceleration time when the outputfrequency is in a prohibited frequency range. The value of the Ramp Time Factor is multipliedwith the value of P3.4.2 (Acceleration Time 1) or P3.4.3 (Deceleration Time 1). For example,the value 0.1 makes the acceleration/deceleration time ten times shorter.ABCDEF [s][Hz]Fig. 27: The parameter Ramp Time FactorA. Output FrequencyB. High LimC. Low LimD.
