When the upper limit set for analog or PULSE frequency, P0.13 as
the set point offset, superimpose the offset frequency and P012
setting upper limit frequency values, as the final limit frequency
value.

Carrier frequency
Settln Ran e
This function adjusting carrier inverter. By adjusting the carrier
frequency can reduce electrica.I noise, to avoid the resonance point
of mechanical system, reduce the line of floor drain current and
reducing interference caused by inverter.
When the carrier frequency is low, the output current of higher
harmonic component increases, motor loss increases, the motor
temperature increases. When the carrier frequency is higher, the
motor loss is reduces, the motor temperature rise reduces, but the
loss of the inverter increases, the temperature rise of the inverter
increases, increased interference.
Adjusting the carrier frequency will affect the performance of the
following:
