Product Description:

The 502-03638-11R2 is a motion-control processor card produced by Kollmorgen for the PIC900 Drives series. Installed in a multi-slot rack, it coordinates servo loops, trajectory generation, and system I/O so that a complete machine can be managed from one location. By combining nonvolatile program storage with backplane power and communication links, the board serves as the central controller in packaging lines, pick-and-place stations, and other industrial automation cells that rely on precise axis synchronization.

At its core is an 80C186 microprocessor clocked at 16 MHz, which supports the execution of control algorithms and interrupt routines. The firmware can address up to 1 MB of system memory, allowing sizable motion tables and diagnostic data to reside on the card. For end-user applications, 64 kilobytes of code space are reserved as 64 KB of application memory, while recipe data or variables are stored separately in 32 KB of user memory. No external expansion RAM is present, so all real-time variables reside on the internal bus for deterministic cycle times. The board’s 41 mm width supports dense cabinet layouts without obstructing adjacent modules.

The controller can supervise up to 16 servo axes, each updated from the same interpolation cycle to preserve coordinated motion. Programming and diagnostics are handled over the PICPRO host link, which reaches 115200 baud through a 9-pin D connector, while a second user port supports 19.2 Kbaud on a 10-pin screw terminal for HMI panels or barcode readers. Logic circuitry draws 369 mA at +5 V, while a memory-retention supply of 5 µA at +3 V maintains variables when the rack is off. Physical depth is 213 mm, and the overall height is 305 mm, while the width noted above completes a compact footprint for standard enclosures.
