Speed override
Activating override
If control bit 11 (EnableSpeedOverride) has been set to "1" in the
, 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
provides the following process input for activating the speed override:
Stipulate override value
The override value is selected via the nSpeedOverride_a input at the SB
The override value is a percentage of the speed of the current profile.
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.
