The equations apply only to a set value change from standstill (Set value = 0%; Acceler-
ation = 0).
For set value changes less than 100%, two cases for determining the resulting ramp-up
and ramp-down times must be distinguished:
n the maximum acceleration or deceleration is achieved
n the maximum acceleration or deceleration is not achieved
In the following, the calculation of the resulting ramp-up time for the two cases is ex-
plained by means of examples for the ramp-up.
The calculation of a resulting ramp-down time would be performed in the same way using
the parameters
Z110.7– Ramp-down Time and Z110.10– S-Curve Ramp-down Time.
