Product Description:
The MTC-R02.1-E1-NN-NN-NN-FW is a rack-mountable CNC processor module produced by Bosch Rexroth Indramat within the MTC200 CNC Modules series. Installed in control cabinets, the unit orchestrates motion commands, interpolates tool paths, and communicates with up to eight digital drive controllers on a single fiber-optic Sercos ring. By consolidating axis processing and machine I/O coordination, the module serves as the central real-time interface between a numerical control kernel and the distributed servo amplifiers that actuate linear or rotary axes in machining centers, packaging lines, and assembly equipment.
The module operates from a nominal 24 VDC backplane supply, and allowable ripple is limited to 4 Vpp to keep logic circuits within tolerance. Under steady load, it draws no more than 930 mA, yet the power rail must withstand an inrush of 20 A that occurs during cold start when onboard capacitors charge. Internally, the processor and communication ASICs supervise up to 8 motion axes and exchange deterministic data with the drive system through the Sercos interface. Compliance with the IEC 1491 Sercos profile guarantees cycle-synchronous telegrams so velocity, position, and diagnostic words stay aligned across the ring. The loop can host eight Sercos drives per channel, which matches the axis capacity of the module.
Thermal output is capped at 26 W, so cabinet ventilation must remove that heat while respecting the module’s convection-cooled design. The housing carries an IP20 rating, indicating finger-safe openings but no protection against liquids, and it connects to the supply through wiring up to 1.5 mm². With a mass of 1.65 kg, the card slides easily into card guides and occupies only 83.7 mm of front-panel width. Its depth and height measure 152 mm and 192 mm respectively, leaving room for neighboring axis or I/O cards inside compact control racks.
