Product Description:

The MTC-P01.2-E2-A2-A2-NN-FW EP is a CNC communication module manufactured by Bosch Rexroth Indramat for the MTC200 CNC Modules series. Installed in machine-tool control racks, it bridges the numerical controller, the programmable logic layer, and the fiber-optic SERCOS drive network. By distributing setpoint data and collecting status telegrams in real time, the module enables coordinated axis motion, spindle control, and auxiliary functions inside automated production equipment. This arrangement lets the control platform exchange motion commands and operating feedback across several machine functions without separate interface cards for each axis group.

In one optical ring, the hardware supervises 8 drives, and with three rings it can support up to 24 drives without multiplexing. Total link attenuation up to 12.5 dB is accepted, so fiber routing can include connectors and patch panels. The NC-ready output supplies 24 V at 150 mA, providing the handshake needed before external contactors are energized. Connection to the host industrial computer is through the ISA Bus, while field-level logic exchanges data over the Indramat Local Bus through a 50-way ribbon cable. The device follows the IEC 1491 SERCOS standard for deterministic telegram scheduling, which helps maintain stable communication timing when the network is heavily loaded.

If mains power collapses, an internal capacitor bank maintains bus activity for 8 ms, allowing drives to decelerate safely. The optical receiver tolerates signals as strong as -20 dBm and still detects telegrams down to -31.2 dBm, maintaining communication over extended fiber lengths. Transmit power is selectable, with higher output for longer runs and reduced output when short jumpers are sufficient. Cabinet planning is simplified by the module's 131.5 mm width, and the multi-loop layout helps conserve slot space in densely equipped machining centers.
