Under V/F control, this parameter can be set properly to prevent motor vibration

of the motor. When the inverter operates at low frequency without load, the

greater the motor power is, the greater the vibration of motor will be. This

parameter can be increased to restrain the vibration of motor. When carrier freq. is

smaller, this parameter can be adjusted lower to reduce vibration.

This function can adjust output frequency properly as the load varies to

motor speed is in constant value. If acting with automatic torque boost function,

better low speed moment characteristic can be obtained. As shown in Fig.7-10.

Carrier frequency

Range: 0.5～16.0K

type

Carrier freq. mainly affects motor noise and heat loss when running. Relationship

among carrier freq, motor noise, and leak current is as follows:

When carrier freq. goes up (Ĺ), the motor noise is reduced (Ļ), leakage current of

the motor is increased (Ĺ), and the interference is increased (Ĺ);

When carrier freq. goes down (Ļ), the motor noise is increased (Ĺ), leakage current

of the motor is decreased (Ļ), and the interference is decreased (Ļ).

When the ambient temperature is high, and the motor load is heavy, reduce the

carrier freq. properly to reduce thermal loss to the inverter.

Units digit: Carrier freq. is adjusted automatically according to temperature

0: Banned.

1: Allowed.

Carrier frequency changes based on temperature, which refers to inverter check

that the radiator temperature is relatively high, it automatically reduces carrier

freq., so as to reduce inverter temperature rise. When radiator temperature is

relatively low, carrier freq. gradually restores to set value. This function can

reduce inverter overheat alarm.

revolving speed at low speed.

Thousands digit: Asynchronous modulation, synchronization mode (valid

under V/F control)

0: Asynchronous modulation.

1: Synchronous modulation (under 85Hz: Asynchronous modulation).

1.When units digit is set as 1, after reaching overheat warning

alarm point, carrier wave will decrease to 1.5KHz; when the

temperature decrease to 5℃ lower than overheat warning alarm

point, carrier freq. will automatically rise to the set carrier freq.

2. Synchronous modulation, it means that carrier freq. changes

when output frequency changes, it guarantees that the ratio

(carrier ratio) between the two does not change, generally used

Note

when output frequency is high, conducive to input voltage quality.

When output frequency is low(85Hz or below, generally no need of

synchronous modulation , so at this time carrier freq. and output

frequency ratio is relatively high, advantages of asynchronous

modulation are more apparent. When operating frequency is

higher than 85Hz , Synchronous modulation is valid, frequency

lower than this is fixed with asynchronous modulation mode.

3. By this way, some incontinuity parameter can be together to

read the data, and using the input mapping application parameter

to increase the communication efficiency. For example, if reading

Parameter F06.01 ~ F06.06 is used to set analog quantity input voltage and its

representative set value relationship. When analog quantity input voltage is

greater than the set “Max. input”(F06.05), analog quantity voltage is calculated

based on “Max. input”; similarly, When analog input voltage is smaller than the

set “min. input ”(F06.01), Set based on “ curve lower than min. input setting

and 2 are three-point straight line, while curve 3 is four-point

curve, which can realize more flexible corresponding relationship.

motor during stop by control terminal so as to realize emergency stop and accurate

position of the motor. During deceleration stop, if this function terminal closed,

when frequency is lower than the brake starting frequency F02.14, it will brake

according to brake current defined in F02.16. It will not stop until terminal is

opened.

28: Inverter running prohibited. The running inverter stops freely when

this terminal is effective, and forbidden to start in waiting status. It is mainly

applied to occasion needing safe linkage.

29: Acceleration/deceleration prohibited command. When this function is
