Product Description:

The MTC-P01.2-M1-A2-A2-NN-FW EP module is a computer numerical control card manufactured by Bosch Rexroth Indramat for the MTC200 CNC Modules series. Installed in an industrial PC rack, the card acts as the central motion processor, linking drives, I/O, and higher-level PLC logic so that multiple machine axes can move in coordinated real time. It provides the computational layer required for precise interpolation, position feedback handling, and drive command distribution in automated machining cells.

Designed for advanced machines, the controller supports 8 axes with a co-processor, allowing the main CPU to offload interpolation tasks to a dedicated signal processor. The hardware footprint follows the ISA bus plug-in card format, so it occupies a single long slot inside legacy or hybrid PC chassis. Motion commands reach the drive amplifiers through SERCOS fiber optics, eliminating electrical noise and enabling deterministic timing. A supplementary expansion connector based on PC/104 permits local add-on boards, while a memory pool of 1 MB RAM buffers tool-path blocks and diagnostic data. Two A2 option modules are already fitted, and an export limit caps coordinated interpolation at four axes to comply with control regulations.

Up to 24 drives can be addressed from the single optical loop, and the optical budget is maintained as long as total cable loss stays below 12.5 dB. When the host PLC requests cycle start, an NC-ready relay delivers 24 V, 150 mA to confirm control availability. A capacitive power reserve guarantees operation for a minimum of 8 ms after a mains failure, preventing axis runaway while the PC shuts down. The card connects to the machine-level PLC through a 50-way ribbon that carries the Indramat Local Bus, and one empty expansion slot remains for future fieldbus or memory upgrades. Physical mounting is restricted to industrial PCs equipped with adequate ISA backplanes.
