3.10 Acceleration and deceleration times T

The ramp generators (main set-value, set-value 2) are
programmed using the acceleration and deceleration times. Under
C012 and C013, the ramp generator for the main set-value (Set-
value 1/JOG frequency) receives its standard setting.
The acceleration and deceleration times refer to a change of the
field frequency from 0 to the maximum field frequency set under
C011. The times to be set are calculated as follows:
T = t

Code Parameter Meaning Acceptance
C012 5.0s
0.0...990s Standard acceleration time for main set-
value ON-LINE
C013 5.0s
0.0...990s Standard deceleration time for main set-
value ON-LINE
For programming and activation of additional acceleration and
deceleration times see page 81.
For ramp generator of set-value 2 see page 66.
