This function adjusting carrier inverter. By adjusting the carrier frequency can reduce electrical 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:
Carrier frequency
Low →high
The motor noise
Large → small
The output current waveform
Bad →good
Temperature Rise in Electric Motors
High → low
The temperature rise of the inverter
Low → high
leak current
Small →
large
Foreign related interference
Small → large
Different power inverter, the carrier frequency of the factory Settings is different. Although the user can according to need to
modify, but need to pay attention: if the carrier frequency set to a higher value than the factory, will lead to inverter radiator
temperature increase, the user needs to use of inverter derating, otherwise the inverter is in danger of overheating alarm.
P0.18
Carrier frequency adjustment with temperature
Default
1
Setting Range
0:No
1:Yes
Carrier frequency with the temperature adjustment, is refers to the inverter is detected its radiator at high temperature, reduce
the carrier frequency automatically, for lowering the temperature rise of the inverter. When the radiator at low temperature,
carrier frequency returning to the set value. This feature can reduce overheat alarm of inverter.

To meet the needs of all kinds of scene, ED2000 provides three kinds of deceleration time units, 1 seconds, 0.1 seconds,
respectively, and 0.01 seconds.
Note: Modify the function parameters, four groups of decimal digits, as suggested by the deceleration time will change, the
corresponding deceleration time changes, also pay special attention to in the course of application.
P0.21
Frequency offset of auxiliary frequency source for
X and
Y operation
Default
0.00Hz
Setting Range
0.00Hz- Maximum frequency P0.12
This function code is only valid at the time of frequency source selection of the advocate complementary computing.
When frequency source of the advocate complementary computing P0.21 as offset frequency, and advocate complementary
computing results superposition frequency value, as the final frequency setting, make frequency setting be more flexible.
P0 .22
Frequency reference
Default
2
Setting Range
1
0.1Hz
2
0.01Hz
All the parameters used to determine the resolution of the function code associated with the frequency.
When the frequency resolution of 0.1 Hz, ED2000 maximum output frequency can reach 3200 Hz, and the frequency resolution
of 0.01 Hz, ED2000 maximum output frequency of 320.00 Hz.
