EM303A General Purpose Inverter
84
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 the JOG button or terminal JOG is on.
Otherwise, it will be considered as the jog command cancelled.
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:
Motor Rated Power Pe
≤15kW ≤30kW ≤75kW ≤132kW ＞132KW
Carrier Frequency Fc ≤10.0kHz ≤8.0kHz ≤6.0kHz ≤4.0kHz ≤2.5kHz
