These parameters are used to define the set frequency and acceleration/deceleration time of the frequency
inverter when jogging. The startup mode is fixed as "Direct start" (b1-00 = 0) and the stop mode is fixed as
"Decelerate to stop" (b1-07 = 0) during jogging.

The EM11 provides a total of four groups of acceleration/deceleration time, that is, the above three groups
and the group b0-21 and b0-22. Definitions of four groups are completely the same, for more details, see the
description of b0-21 and b0-22. You can switch over between the four groups of acceleration/deceleration
time through different state combinations of DI terminals. For more details, see the descriptions of b3-01 to
b3-011.

If the setting frequency is within the jump frequency range, the actual running frequency is the jump
frequency close to the set frequency. Setting the jump frequency helps to avoid the mechanical resonance
point of the load.
The EM11 supports two jump frequencies. If both are set to 0, the frequency jump function is disabled. The
principle of the jump frequencies and jump amplitude is shown in the following figure 6-6.

It is used to set whether the jump frequencies are valid during acceleration/deceleration.
When the jump frequencies are valid during acceleration/deceleration, and the running frequency is within
the frequency jump range, the actual running frequency will jump over the set frequency jump amplitude
(rise directly from the lowest jump frequency to the highest jump frequency). The following figure shows
the diagram when the jump frequencies are valid during acceleration/deceleration.
