Define the combination of 3 operation command channels and 9 frequency reference
channels for easily synchronously switching.
The principle for above frequency source reference channel is same as frequency source
master setting selection F0.03, please see the description of F0.03 function code. The different
running command channel can be bundled with the same frequency reference 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source , the set frequency source by F0.03 to F0.07 is no longer valid.

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.
ST500 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 third group: F7.10, F7.11;
The second group: F7.08, F7.09;
The fourth group: F7.12, F7.13.

To meet the demand of the various on-site, ST500 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, and all ac/deceleration times will change
accordingly.

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.

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.
