Product Description:
The MTC-R02.1-M1-A2-A2-NN-FW is a CNC controller module produced by Bosch Rexroth Indramat for the MTC200 CNC Modules series. In a multi-axis machining cabinet, the module acts as the master for linked drives and centralizes axis coordination for the control system. It exchanges motion commands over a fiber-optic ring to coordinate spindle and feed axes in automated production cells.
The module is powered from a control rail that delivers 24 VDC. Operation continues down to a brownout threshold of 18 VDC, so the cabinet power supply must stay above that level during transients. At switch-on, the electronics draw an inrush of 20 A before settling to a steady current that does not exceed 930 mA. A separate watchdog relay line is used for fault signaling and carries up to 150 mA. Protective grounding is routed through a ground conductor sized at 6 mm², matching common machine-tool bonding bars. Communication with the drive loop occurs through the optical SERCOS interface, while internal logic is maintained by the 24 V backplane bus that occupies two adjacent rack slots. The enclosure is molded from PA6.6 GF30 and carries an IP20 rating, preventing finger contact with live circuits but requiring installation inside a closed cabinet.
The control section supervises up to 8 drives per optical loop and can handle 24 total axes through three loops, allowing complex gantry or transfer lines to run from a single CPU card. Cabinet layout is simplified by the compact footprint: width is 83.7 mm, height is 192 mm, and depth matches a standard Eurocard cage so airflow is not obstructed. Shipping weight is 1.65 kg, which reduces load on vertical card guides during installation and removal. Two rack slots are reserved, leaving room for both front diagnostic LEDs and the rear fiber connectors without crowding neighboring modules inside the rack.
