8.11.1 Speed override
Activating override
If control bit 11 (EnableSpeedOverride) has been set to "1" in the MCK control word
, a speed
override is carried out in accordance with the stipulated override value.
If the Motion Control Kernel is downstream from the MCKInterface in the circuit, the
L_MckCtrlInterface
provides the following process input for activating the speed override:
Stipulate override value
The override value is specified via the nSpeedOverride_a input at the
LS_MotionControlKernel
SB. The override value is a percentage of the maximum traversing
speed, which depends on the set machine parameters.
Deactivate override
If control bit 11 (EnableSpeedOverride) is reset to "0", travelling takes place at the speeds
that have been specified by means of the profile parameters. Acceleration/deceleration
from the speed defined with override to the speed set in the profile takes places
immediately in this case.
Deactivating the override within the braking/deceleration ramp does not have any effect.
