8.6.8 SFC acceleration time
In frequency-controlled machines, you can set the change speed for the speed in the
Fixed speed
and
External speed control operating modes. This will prevent pressure peaks caused by an ex‐
cessively fast acceleration of the speed.
Ramp up time is the time from minimum speed to reaching the machine-specific maximum speed.
The values for
Ramp up time and Ramp down time: which can be set at SIGMA CONTROL 2
are added to the similar parameters that have already been set in the FC.
