The object list is static: relay and digital input status, relay commands, run/stop and direction commands, two speed references, drive measurements, energy meters, fault history and a parameter mailbox (AV25/AV26 with BV15/BV16). It predates the ACH580 list, which reuses many of the same instance numbers.",
