8.4.2 Min/Max speed
For the " Speed follower " operating mode, yo can initially limit the speed setpoint by means of the
following parameters:
In the »Engineer», you can set the initial limit by means of the dialog box Min/Max speed.
• Open the Min/max speed dialog box by opening the Application Parameters tab and clicking on
the following button on the dialog level Overview  Signal flow:
Speed setpoint generation
When the speed limit values are set, the Motion Control Kernel influences the setpoint generation
with a synchronisation mode The synchronisation mode serves to travel the synchronisation range
dynamically with the synchronisation ramp set in C02610/2 . Synchronisation always starts in the
zero crossing of the defined speed.
[8-14] Example: Speed setpoint generation in the "Speed follower" operating mode (with nSpeedAddValue_v = 0)
