F3.27 Output terminals valid mode selection
It is used to set the logic of output terminals Y1, Y2, relay R, .relay R

F4.00 JOG running frequency
F4.01 JOG acceleration time
F4.02 JOG deceleration time
These parameters are used to define the set frequency and acceleration/deceleration time of the inverter
when jogging. The startup mode is "Direct start" (F7.00 = 0) and the stop mode is "Decelerate to stop" (F7.10
= 0) during jogging.
F4.03 Acceleration time 2
F4.04 Deceleration time 2
F4.05 Acceleration time 3
F4.06 Deceleration time 3
F4.07 Acceleration time 4
F4.08 Deceleration time 4
The JT550 provides a total of four groups of acceleration/deceleration time, that is, the preceding three
groups and the group defined by F0.17 and F0.18. Definitions of four groups are completely the same. You
can switch over between the four groups of acceleration/deceleration time through different state
combinations of X terminals. For more details, see the descriptions of F2.00 to F2.04

F4.10
F4.11 Frequency jump amplitude
If the set frequency is within the frequency jump 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 JT550 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 .
