To meet the need of all kinds of scene, VD120 provides three kinds of acceleration/deceleration time
units, is 1 seconds, 0.1 seconds and 0.01 seconds respectively.
Note: modify the function parameters, 4 groups of acceleration/deceleration time display the decimal
digits will change, the corresponding acceleration/deceleration time also change, should pay attention
to in the process of application.

Acceleration/deceleration time, refers to the acceleration/deceleration time from frequency zero to
F0-21 set frequency, figure 6-1 is acceleration/deceleration time diagram.
When F0-21 select for 1, the acceleration/deceleration time is associated with set frequency, if set
frequency change frequently, the acceleration of motor is change, need to pay attention to in
applications.

○
Define the bound combination between three run command channel and nine kinds of frequency
given channel, convenient to realize synchronous switch.
The meaning of the above frequency for given channel is same with the main frequency source A
selection F0-02, please see the description of F0-02 function code.
The different run command channels can be bound to the same frequency given channel.
When the command source has bundled frequency source, during the effective period of this
command source, the set frequency source of F0-02~F0-07 is no longer work.
