5.2.5 Additional acceleration and deceleration times
For the ramp generator of the main set-value (set-value 1/JOG
frequency) you can call additonal acceleration and deceleration
times from the memory, e.g. to change the acceleration speed of
the drive as from a certain speed.
Programming of additional acceleration and deceleration
times
The ramp times are set in two steps, under C100, one pair of
acceleration and deceleration times is selected.
•
Select an additional acceleration/deceleration time under C100
•
Set the desired acceleration time under C101 and the desired
deceleration time under C103.
If you need several additional ramp times, repeat the two steps
correspondingly.
To calculate the values to be entered, please observe the information
on page 72.
A maximum of 15 additional acceleration and deceleration times
can be programmed.

Assignment of the digital inputs
The number of required inputs for the function "Enable additional
acceleration/deceleration times" depends on the amount of the
required additional ramp times.
Number of required acceleration and deceleration
times
Number of required inputs
1 at least 1
2...3 at least 2
4...7 at least 3
8...15 4
A maximum of four inptus can be assigned to this function. For the
assignment of the inputs see the notes on page 78.
