d3-01 to d3-04: Jump Frequencies 1, 2, 3 and Jump Frequency Width
The Jump frequencies are frequency ranges at which the drive will not operate. The drive can be programmed with three
separate Jump frequencies to avoid operating at speeds that cause resonance in driven machinery. If the speed reference
falls within a Jump frequency dead band, the drive will clamp the frequency reference just below the dead band and only
accelerate past it when the frequency reference rises above the upper end of the dead band.
Setting parameters d3-01 through d3-03 to 0.0 Hz disables the Jump frequency function.
Figure 2.33 shows the relationship between the Jump frequency and the output frequency.
Figure 2.33
Figure 2.33 Jump Frequency Operation
Note: 1. The drive will use the active accel/decel time (C1-01 and C1-02) to pass through the specified dead band range, but will not allow
continuous operation in that range.
2. Do not overlap parameters when setting more than one Jump frequency.
No.
<1> The upper limit is determined by the maximum output frequency (E1-04) and upper limit for the frequency reference (d2-01).
