Product Description:

The 502-04011-01 processor card is manufactured by Kollmorgen as part of the PIC900 Drives series. Mounted on the system back-plane, it supplies the real-time control needed to schedule servo loops, handle serial traffic, and translate supervisory commands into deterministic position or velocity updates. Through this role, the card anchors coordinated motion in packaging, material-handling, and assembly equipment by converting plant-level instructions into pulse-by-pulse torque references for the connected power stages. Its back-plane location also lets it distribute timing and command activity across the drive rack from a central control point.

An 80486DX2 CPU clocks at 32 MHz to service interrupt cycles quickly enough for one axis at the 0.25 ms loop rate and up to 32 axes when the loop is stretched to 8 ms. Program storage consists of 512 K of application memory, complemented by 256 K of general RAM and a separate 64 K user block reserved for parameters and diagnostics. The logic section draws 800 mA from the regulated +5 V bus, a load that the rack supply must support continuously. Hardware flow control uses RTS/CTS, with a maximum PICPRO port speed of 115.2 kbaud and a user channel limit of 19.2 kbaud, so operator panels and host PCs can exchange setpoints and status in real time.

The board has a depth of 213 mm, a height of 305 mm, and a slim width of 41 mm, allowing dense stacking inside control enclosures. The narrow profile helps the module fit into compact rack layouts without requiring excessive lateral space. A standby circuit draws only 15 µA from the lithium battery, preserving nonvolatile data during extended power outages. For equipment exposed to vibration or handling shocks, the assembly tolerates impacts up to 15 g / 11 ms without functional loss.
