8.5.2
Requesting the operating mode
Request for "speed follower" operating mode by means of the
If the
MCKInterface
is connected upstream to the
Motion Control Kernel
and if the operating mode
is requested at 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
and, optionally, the process controller
upstream of the
nSpeedSetValue_a
process input.
• The speed setpoint is limited internally to the speed limits set in
.

Note!
In the "
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
