Product Description:

The MTC-P01.2-E2-NN-NN-NN-FW is a CNC processor module produced by Bosch Rexroth Indramat for the MTC200 CNC Modules series. It plugs into an industrial controller rack and coordinates axis motion, spindle commands, and peripheral tasks for machine-tool automation. By handling interpolation and supervising drive commands, the unit forms the control core that links operator inputs with servo amplifiers on the plant floor.

This module mates with an ISA back-plane, so data exchange follows the timing and address structure of that bus. One terminal can supervise 3 complete CNC systems, allowing multi-channel machining from a single card. It can address up to 8 drives over the optical SERCOS interface; fiber quality is considered acceptable when total path loss stays within 12.5 dB. For outbound traffic the transmitter delivers a maximum optical level of -3.5 dBm, ensuring sufficient headroom before saturation. Indramat Local Bus handles PLC signaling through the SPS link, while a 50-way ribbon cable provides the SPS connection to parallel I/O boards. A power-fail lead time of 8 ms lets the CPU finish bus cycles before supply collapse, and the 131.5 mm card width fits standard Euro-format mounting rails. All parameters are delivered without export restrictions, simplifying cross-border service logistics.

The receive path is protected by an upper optical limit of -5 dBm and continues to decode frames down to -20 dBm, giving generous margin for connector losses or aging fibers. A dedicated NC-ready line sources 150 mA at a logic level of 24 V; this output signals to external relays that motion commands are valid once internal self-tests have finished. Together, these thresholds and status circuits complement the transmission figures in the previous paragraph by confirming link integrity, verifying power-on sequencing, and isolating the control logic from field wiring transients.
