The drive accelerates or decelerates the motor smoothly until the frequency reference is not in the range of the
Jump frequency band. The drive will use the active accel/decel time to go through the specified dead band range.
If the frequency reference is not in the range of the Jump frequency band, switch to constant speed operation.
Figure 11.63 Jump Frequency
Note:
• When you set Jump Frequencies 1 to 3, make sure that the parameters do not overlap.
• When the drive is in the range of the Jump frequency, the frequency reference changes automatically. When Jump is executed, the
output frequency changes smoothly as specified by the values set in C1-01 [Acceleration Time 1] and C1-02 [Deceleration Time 1].
