Value Range Description
F8‑11
Jump frequency
amplitude
0.00 Hz 0.00 Hz to 5.00 Hz
When the running frequency approaches the jump
frequency during acceleration, the AC drive runs for a
period at the current running frequency and then jumps
over the jump frequency. The jump range is twice F8‑11
(jump frequency amplitude).
When the running frequency approaches the jump
frequency during deceleration, the AC drive runs for a
period at the current running frequency and then jumps
over the jump frequency. The jump range is twice F8‑11
(jump frequency amplitude).
F8‑22
Enabling/
Disabling the
jump frequency
during
acceleration and
deceleration
0
0: Disabled
1: Enabled
Used to enable or disable the jump frequency function
during acceleration/deceleration.
If this parameter is set to 0, when the running frequency
approaches the jump frequency during acceleration/
deceleration, the AC drive continues running at the
current frequency.
If this parameter is set to 1, when the running frequency
approaches the jump frequency during acceleration/
deceleration, the AC drive jumps over the jump
frequency. The jump range is twice F8‑11 (jump
frequency amplitude).
3.5.2.4 Reverse Frequency Inhibition
You can set F8‑13 to disable reverse frequency. The following figure shows the
diagram of disabling reverse frequency.
The motor rotation direction is set through F0‑09. By editing F0‑09, you can change
the motor rotation direction without changing motor wiring. Editing this parameter is
equivalent to exchanging any two of the motor U, V, W cables.
Note
After the parameter is initialized, the original rotation direction of the motor is resumed. Ex‑
ercise cautions when using this function if motor rotation direction change is prohibited
after system commissioning is complete.
