Parker SSD 590 Series Technical Notes

The Evolution of 590 Series Architecture

The 590 Series was introduced by SSD Drives (formerly Eurotherm Drives) in the late 1980s as a successor to the analog 580 Series platform. The initial 590 variants used hybrid analog/digital control boards with EPROM-based parameter storage. By the mid-1990s, Parker's acquisition of SSD brought full digital parameter management via the P3 operator panel and serial communications via RS-422/RS-485 (Modbus RTU). The 590C (Commander) and 590P (Plus) sub-variants introduced enhanced field supply regulation and expanded I/O mapping. The 591C extended the platform to four-quadrant regenerative operation. Later firmware revisions (version 7.x onward) added CANopen and DeviceNet adapter compatibility via plug-in option cards. The 590 Series entered its end-of-active-production phase circa 2010–2015, with Parker transitioning customers toward the Quantum III and then the Mentor MP platform. However, the installed base remains extensive, and replacement circuit boards — including the AH385851U003 — remain in active demand for lifecycle extension programs.
