If the assignment of a drive parameter to the Process Channel is replaced with the assignment of a larger
parameter, the following Bytes of the object
Data Channel Descriptors, involved in the operation
must be cleared. If the assignment can not be correctly carried out , the response is negative.
IMPORTANT
In the current versions ot the
cards there is no control on the validity of the assignment of the
drive parameters to the Process Data Channel; the user, therefore, must control with care such assignment,
for example, the overlap of parameters or the overflow of the Process Data Channel capacities. In
the case these assignments are not carried out in a proper way, the system could behave in an unexpected
and potentially dangerous way.
