Acceleration time refers to the time required that frequency inverter from zero frequency acceleration
to acceleration/deceleration reference frequency (F0-21), as show in figure 6-1 in the t1.
Deceleration time refers to the time required that frequency inverter from deceleration/deceleration
reference frequency (F0-21) deceleration to zero frequency, as show in figure 6-1 in the t2.

VD500 provide 4 groups acceleration/deceleration time, user can use digital input terminal DI switch
selection, 4 groups of acceleration/deceleration time through following function code to set:
The first group: F0-17, F0-18; The second group: Fb-03, Fb-04;
The third group: Fb-05, Fb-06; The forth group: Fb-07, Fb-08;

To meet the need of all kinds of scene, VD500 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.
