d2-03: Master Speed Reference Lower Limit
Sets a lower limit as a percentage of the maximum output frequency that will only affect a frequency reference entered from
the analog input terminals (A1 or A2) as the master speed reference. This is unlike parameter d2-02, which affects all frequency
references regardless of their source.
Note: When lower limits are set to both parameters d2-02 and d2-03, the drive uses the greater of those two values as the lower limit.

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.
No. Parameter Name Setting Range Default
d3-01 Jump Frequency 1 0.0 to 240.0 Hz 0.0 Hz
d3-02 Jump Frequency 2 0.0 to 240.0 Hz 0.0 Hz
d3-03 Jump Frequency 3 0.0 to 240.0 Hz 0.0 Hz
d3-04 Jump Frequency Width 0.0 to 20.0 Hz 1.0 Hz
Figure 4.32 shows the relationship between the Jump frequency and the output frequency.
