MC_WriteParameter - Example of "Override"
Example of changing parameters with "Override"
Factors can be superimposed online on the current traversing velocity or
acceleration / deceleration ramp. Speed override affects the velocity, acceleration
override affects acceleration and deceleration.
Set the following input parameter values, in order to set velocity override:
ParameterNumber = 4142
Value = 0 to 200 (in [%])
Set the following input parameter values, in order to set acceleration override:
ParameterNumber = 4141
Value = 1 to 1000 (in [%])
MC_WriteParameter - Example of "Drive control word"
Drives coupled via PROFIBUS communicate by means of the standard telegrams.
These telegrams contain up to two control words for the drives. The content of
those words is specified in the PROFIdrive standard.
