channel. When command source has the available frequency source for bundling, in the valid
period of command source , the set frequency source by F0.03 to F0.07 is no longer valid.
F0.13
Acceleration time 1
F0.14
Deceleration time 1
Acceleration time refers to the required time when the inverter accelerates from zero
frequency to F0.16.
Deceleration time refers to the required time when the inverter decelerates from F0.16 to
zero frequency.
PI9000 provides four groups of ac/deceleration time, user can select by using the digital
input terminal DI, as follows:
The first group: F0.13, F0.14;
The second group: F7.08, F7.09;
The third group: F7.10, F7.11;
The fourth group: F7.12, F7.13.
Ac/Deceleration time
F0.15
unit
To meet the demand of the various on-site, PI9000 provides three kinds of time unit: 1
second, 0.1 second and 0.01 second respectively.
Note: when modifying the function parameters, the number of decimal places that the
four groups of ac/deceleration time displayed will change displayed, the ac/deceleration time
will change accordingly.
Ac/deceleration time
F0.16
reference frequency
Ac/deceleration time refers to the required time from zero frequency to F0.16 or from
F0.16 to zero frequency.
When F0.16 selects 1, the ac/deceleration time depends on the set frequency, if the set
frequency change frequently, and the acceleration of the motor is varied, please use with
caution.
Carrier frequency
F0.17
adjustment as per
temperature
The adjustment of carrier frequency refers to that the inverter automatically adjusts the
carrier frequency according to the radiator temperature, so as to reduce the carrier frequency
when the radiator temperature rises, and to restore the carrier frequency when the radiator
temperature reduces.
F0.18
Carrier Frequency
This function is mainly used for improving the noise and vibration phenomena that the
inverter operation may occur If the carrier frequency is higher, there are more ideal current
waveform and less motor noise. It is very applicable in the place to be muted. But at this
time, the switching loss of main components is large, the whole unit fevers, the efficiency
decreases and the output reduces. At the same time, there is a bigger radio interference,
another problem is that the capacitive leakage current increases when running at the high
