The override
the LS_MotionControlKernel
acceleration that has been set for the respective operating mode (referencing, manual jog,
positioning etc.) in the corresponding profile parameter.
The acceleration override results in a deceleration override. Both ramps are evaluated by
multiplication by the acceleration override until the deceleration process sets in.
Identifier
nAccOverride_a
Deactivate override
If control bit 12 (EnableAccOverride) is reset to "0", travelling takes place at the acceleration
rates specified by means of the profile parameters. "Ramping up" from the acceleration
defined with override to the acceleration set in the profile takes place immediately in this
