A-22 Serial Communications 590 Series DC Digital Drive
List of PNO Assignments
The serial link parameter numbers (PNO) include dedicated parameters, and also 16 configurable parameters. These vary
with each Drive type.
590
The 16 configurable parameters have PNO's 112 to 127. These can be made to point to any TAG number, either via the
MMI (PNO CONFIG), or via the serial link.
PNO's 96 to 111 are actually the pointers associated with PNO's 112 to 127.
For example:
By MMI, if PNO112 = 123, then PNO 112 will access TAG number 123.
Over serial link, if PNO96 = 123, then PNO 112 will again access TAG number 123
