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.
Carrier frequency

adjustment
Setting Range
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, canier frequency
returning to the set value.This feature can reduce overheat alarm of
inverter.

Setting Range
To meet the needs of all kinds of scene, MT-2000 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.

Setting Range
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 sett i ng be more flexible.
