Product Description:

The MTC-P01.2-E2-A2-A2-NN-FW is a CNC processor module from the MTC200 CNC Modules series produced by Bosch Rexroth Indramat. Installed in the control rack of a machine tool, it coordinates axis motion and program execution so that servo drives, I/O, and operator commands are synchronized in real time. By acting as the central numerical control inside an automated cell, it links the motion subsystem with higher-level PLC logic and front-end HMIs.

This module communicates with the back-plane through the ISA Bus, allowing legacy PC hardware to exchange data with motion functions at deterministic cycle times. Drive commands are issued over a SERCOS Fiber Optics ring, providing noise-immune transmissions and galvanic isolation between control electronics and power components. Status feedback is presented locally on a 1-digit 7-segment display that shows coded diagnostic messages during boot, run, or fault states. Internally, two axis boards are already mounted, and the base card can directly host up to 8 drives without additional expansion. With add-on axis modules the controller grows to a ceiling of 24 drives, enabling multi-spindle or multi-gantry machines to be handled by one processor.

The optical link remains reliable as long as total attenuation stays within 12.5 dB, a margin that includes connector and fiber losses across the entire ring. Cabinet space is conserved by a front width of 131.5 mm, permitting dense packing of related motion and I/O cards. When the machine control voltage is present, an NC-ready signal of 150 mA is sourced at 24 V for downstream interlock circuits. Should mains fail, internal capacitors sustain logic for 8 ms so that motion can be brought to a controlled stop. An SPS interface on a 50-way ribbon cable transfers start, stop, and override bits between the CNC and the discrete PLC layer, keeping program flow coordinated with field actuators.
