8.3.2 Setpoint selection
The speed setpoint is selected via the nSpeedSetValue_a process input and additively via the
nSpeedAddValue_v process input.
• Usually, the ramp generator L_NSet and, optionally, the process controller L_PCTRL are
upstream of the nSpeedSetValue_a process input.
• The speed setpoint is limited internally to the speed limits set in C02611/1...4 .
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 :
[8-4] Example: Speed setpoint generation in the "Speed follower" operating mode (with nSpeedAddValue_v = 0)
