Product Description:
The 502-03846-00R3 is a processor module manufactured by Kollmorgen for the PIC900 Drives series. Positioned in a 1/2-slot location of the system rack, it supplies the control logic that coordinates drive functions, position loops, and machine I/O in industrial automation cells. By executing compiled motion programs and exchanging data through dedicated serial links, the unit serves as the central command resource for every connected PIC900 power stage. This arrangement keeps motion control functions centralized while the connected power stages handle motor output.
An on-board CPU clock of 8 MHz determines instruction timing, while the controller’s program space includes 128K of application memory for firmware and motion libraries. Real-time variables are held in 64K of battery-maintained RAM, and operators can store custom parameters in a separate 32K user memory block. Runtime electronics draw only 1 A from the single-phase AC feed yet can deliver up to 40 W of regulated logic power for internal buses and peripheral ports. This low-current, moderate-output profile minimizes panel heat but still allows simultaneous processing, communications, and diagnostics without performance throttling.
The module’s backup supply is a 1.2 Ah 3 V 2/3A Lithium cell that preserves RAM contents during mains loss. Program loading and drive tuning are handled through a PicPro RS232 service port that operates to 57600 baud, while machine-level exchanges use a separate user RS232 channel rated for 19.2 Kbaud. Keeping the service and user channels separate helps isolate programming traffic from normal machine communication during operation. Input line power lands on a 3-terminal plug connector, simplifying field replacement. Physical dimensions of 2.4 in width, 8.4 in depth, and 12 in height let the board fit densely populated enclosures yet maintain clearance for airflow.
