AC10 Inverter
The setting value of V/HZ curve is set by motor load characteristic.
Note:
V1<V2<V3<V4<V5<V6
,
F1<F2<F3<F4<F5<F6.As with low-frequency, if the voltage setting is too
high, the motor will overheat or be damaged. Inverter will be stalling or occur over-current protection.
Note: During the
process of Flycatching,
polygonal-line V/Hz
curve function is
disabled. After
Flycatching is finished,
this function is enabled.

This function can meet the needs of some special loads, for example, when the frequency
outputs 300Hz and corresponding voltage outputs 200V (supposed voltage of inverter power
supply is 400V), turnover frequency F118 should be set to 300Hz and F152 is set to
(
200÷400
)
×100=50. And F152 should be equal to 50.
CAUTION: Please pay attention to nameplate parameters of motor. If the motor is not rated as
inverter-duty; if the inverter output voltage is higher than rated voltage of the motor windings;
or if the inverter output volts-per-hertz ratio is not the same as the motor specifications, the
motor will be damaged.
Carrier-wave frequency of inverter is adjusted by setting this code function. Adjusting carrier-
wave may reduce motor noise, avoid point of resonance of mechanical system, decrease
leakage current of wire to earth and the interference of inverter.
When carrier-wave frequency is low, although carrier-wave noise from motor will increase, the
current leaked to the earth will decrease. The wastage of motor and the temperature of motor
will increase, but the temperature of inverter will decrease.
When carrier-wave frequency is high, the situations are opposite, and the interference will
raise.
When output frequency of inverter is adjusted to high frequency, the setting value of carrier-
wave should be increased. Performance is influenced by adjusting carrier-wave frequency as
below table:
Carrier-wave frequency
Low → High
Motor noise
Loud → Low
Waveform of output current Bad → Good
Motor temperature
High → Low
Inverter temperature
Low → High
Leakage current
Low → High
Interference
Low → High
