8.11.3 S-ramp smoothing override
Activating override
If control bit 13 (EnableSRampOverride) in the MCK control word
is set to "1", S-ramp
smoothing override is executed according to the selected override value.
If the Motion Control Kernel is downstream from the MCKInterface in the circuit, the
L_MckCtrlInterface
FB provides the following process input for activating the S-ramp
smoothing override:
Stipulate override value
Optional stipulation of the override value is carried out via the nSRampOverride_a input at
the LS_MotionControlKernel
SB. The override value is a percentage of the S-ramp time set
in the profile data.
Tip!
Thus it is possible to start a travel profile with S-ramp time and then deactivate
the S-ramp time, e.g. to traverse with a linear characteristic after reaching the
profile speed.
Deactivate override
If control bit 13 (DisableS_Shape) is reset to "0", the S-ramp time specified by means of the
profile parameters is used for profile generation.

BOOL
S-ramp smoothing override
TRUE Activate S-ramp smoothing override
Note!
If the nSRampOverride_a input remains unconnected or if an override value of
"0 %" is selected, activation of the S-ramp override causes deactivation of the S-
ramp time.
• Deactivation of the S-ramp time before the start of a profile with S-ramp time
causes linear ramp generation.
• Deactivation of the S-ramp time during a traversing process, however, is not
accepted immediately in the profile generator, but the profile generator
checks automatically when an online change of the ramp form can be carried
out and then initiates it automatically.

INT
Value for S-ramp smoothing override
• Percentage multiplier (0 ... 100 %) for the currently active acceleration.
• 16384 ≡ 100 % of the parameterised S-ramp time (C01306/1...15
).
• Values > 16384 are ignored.
