Product Description:

Kollmorgen supplies the 502-03846-03R1 as a processing module for the PIC900 Drives series. Within a drive stack, the board executes application code and manages serial communication so that speed, torque, and diagnostic tasks are synchronized with the power electronics. By adding logic resources directly to the drive, it eliminates the need for an external PLC in small or distributed automation cells. It provides onboard memory, battery-backed real-time functions, and multiple serial ports, enabling the surrounding motor inverters to receive deterministic commands and report status to supervisory systems.

The module’s microcontroller runs at 8 MHz, a frequency sufficient for the deterministic ladder and structured-text routines stored in 128K of application memory. During execution it draws only 340 mA of logic power, which helps keep cabinet heat output low. Temporary variables reside in 64K of RAM, while end users can reserve 32K of separate user memory for recipes or parameter sets. Program loading is performed through an RS232 programming port, and a second serial channel acts as the user port with RTS/CTS hardware handshaking for reliable point-to-point exchanges. Time-stamped events stay accurate thanks to a clock that drifts no more than ±1 s/day. When the module needs to energize peripheral sensors, it can source up to 40 W of total power.

The power section supplies a regulated 5 V rail that can deliver 5.0 A, enough to feed neighboring encoder interfaces and opto-isolated I/O. Non-volatile registers remain intact during outages because a 3 V backup battery rated at 1.2 Ah supports the real-time clock and memory retention. Despite these resources, the board occupies only 2.4 in of width, 8.4 in of depth, and stands 12 in high, letting it fit into compact PIC900 enclosures without obstructing airflow. These proportions simplify retrofits when upgrading existing drive cabinets.
