Product Description:
The 502-03994-11 is a processor card for the PIC900 Drives series manufactured by Kollmorgen. Installed in a drive rack, this card provides the computational layer that coordinates axis profiles, I/O tasks, and diagnostic routines for motion systems. By executing compiled application code, it converts high-level positioning commands into deterministic drive instructions, allowing the surrounding power stage to regulate motor torque and speed. In this role, it links the programmable automation controller level with the servo amplifiers that actuate industrial machinery.
At the core of the card is a 80486DX2 microprocessor that runs at 50 MHz, giving it enough cycle time to service multiple interrupts from the drive backplane. Volatile storage consists of 256 KB of RAM used for stack variables and runtime buffers, while non-volatile application code occupies 512 KB of flash so programs remain resident after power loss. Control logic is powered from the cabinet supply through a regulated draw of 1100 mA on the +5 V rail, with additional ±15 V taps carrying only a few milliamps to analog interfaces. These electrical and computational resources allow the module to execute floating-point motion equations within a single scan of the PICPRO operating kernel.
User configuration files are stored in 64 KB of EEPROM that can be rewritten from the front access port. The high-speed maintenance channel communicates with Kollmorgen’s PICPRO software over an RS-232 link at 115.2 Kbit/s, while a second RS-232 port serves the machine PLC at the default 19.2 Kbit/s user rate. Real-time clock retention is sustained by a lithium cell that the board loads with only 15 µA, extending battery life for long idle periods. All electronics fit on a multilayer board that is 305 mm tall, 213 mm deep, and only 41 mm wide, allowing tight side-by-side installation in PIC900 drive cabinets without exceeding airflow clearances.
