Parker ACR Series User Manual

Parker Hannifin
The DAC and ADC values, gains, and offsets are accessed in blocks of eight
parameters each, as shown in the table below. Since each node may
accommodate all 32 analog inputs and outputs, a range of 512 bits is
reserved for each node. The parameter numbers correspond to a range of
33280-33791 for the lowest numbered node, 33792-34303 for the next node,
and so on. The table below shows the parameter mapping for the lowest
number node. For each higher number node, add 512.

These tables appear similar to the other parameter tables for ACR DACs and
ADC’s, but there is no relationship in function. Nor do the other DAC and
ADC commands have any function for ACR9000 extended analog I/O. The
DAC commands assume their use as command outputs for drives, and the
ACR90x0 does not have the type of ADCs that are assumed by other ADC
commands.
