8.5.2 Requesting the operating mode
Request for "speed follower" operating mode by means of the MCK control word:
If the MCKInterface is connected upstream to the Motion Control Kernel and if the operating mode
is requested at the L_MckCtrlInterface
FB, the wOperationMode and bOperationMode_1...8 process
inputs are available.
8.5.3 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

 Note!
In the "Speed follower operating mode without position control, for an "Electrical shaft"
interconnection the actual position value LS_MotorInterface.dnMotorPosAct_p must be
used as master signal if a drift is to be ruled out.
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
