Product Description:

The MTC-P01.2-M1-A2-NN-NN-FW is a processor board from the MTC200 CNC Modules series manufactured by Bosch Rexroth Indramat. The board functions as the numerical control core in multi-axis machining centers and supplies coordinated motion commands to Indramat drives and feedback devices. By hosting axis logic locally, it offloads the main industrial PC and supports deterministic cycle times for contouring, drilling, and tool-change sequences in automated production cells. This arrangement keeps motion processing close to the control hardware during demanding CNC tasks.

The module communicates with the host controller over the ISA bus, so it can be inserted directly into legacy industrial PCs without a custom backplane. Motion commands reach the drives through a SERCOS fiber-optic interface that provides noise-immune, real-time telegrams for closed-loop motion control. Internal calculation is supported by an axis-module coprocessor, and trajectory data are stored in 1 MB RAM. The hardware can supervise up to 8 integrated axes. Of those, a maximum of 4 interpolating axes can execute simultaneous contour moves, which suits typical milling or plasma applications where coordinated path control is required.

Each drive loop can connect eight drives, while only one axis module is installed on this card, which helps keep slot usage low in the host system. The CPU occupies 4 consecutive bytes in the I/O address map, which simplifies host-side configuration and address allocation. Optical transmission tolerates a link loss of 12.5 dB; receiver sensitivity starts at 10 µW, and the transmitter output can reach 450 µW. An NC-ready signal is sourced at up to 150 mA and 24 V, providing a clear readiness status to downstream devices. If mains power is lost, the circuitry retains data for at least 8 ms, allowing the host to park axes or flush buffers before shutdown.
