In Jog running mode, inverter runs at the frequency set by F0-11, the
acceleration/deceleration time taken for running to Fmax is set by F0-12/F0-13.
★
Jog acceleration time is the time taken for the output frequency to rise from 0Hz up to
maximum frequency Fmax. Deceleration time is the time taken for the output frequency
to drop from Fmax down to 0Hz.
★
In jog running mode, keep pressing
JOG
+/-
or terminal JOG is on. Otherwise, it will be
considered as the jog command cancelled.
Please note that the unit of acceleration /deceleration time is second or minute
defined by F3-21.

Increasing carrier frequency could reduce motor noise, but it will result in inverter heating
up. When carrier frequency is higher than the default, the rated power of inverter should
decrease 5% as each increment of 1 kHz carrier frequency.
Correlation between motor rated power and carrier frequency is suggested as following:
