Figure 1.34 Jump Frequency Operation
Note: 1. The drive will use the active accel/decel time to pass through the specified dead band range but will not
allow continuous operation in that range.
2. When using more than one Jump frequency, make sure that d3-01 >= d3-02 >= d3-03.

d4: Frequency Hold and Up/Down 2 Function
■
d4-01: Frequency Reference Hold Function Selection
This parameter is effective when either of the digital input functions listed below is used.
• Accel/decel ramp hold function (H1- = A)
• Up/Down function (H1- = 10 and 11, sets the frequency reference by digital inputs)
• Up/Down 2 function (H1- = 75/76, adds a bias to the frequency reference using
digital inputs)
Parameter d4-01 determines whether or not the frequency reference or the frequency bias
(Up/Down 2) value is saved when the Run command is cleared or the power supply is shut
down.
The operation depends on what function parameter d4-01 is used with.
