Product Description:

The MTC-P01.2-E1-A2-A2-A2-FW CNC controller card is produced by Bosch Rexroth Indramat for the MTC200 CNC Modules series. As an ISA bus plug-in board for installation in an industrial PC, it provides the numerical control layer for multi-axis machining centers and handling systems. Through its SERCOS fiber network and local PLC interface, the module coordinates motion commands and sequence logic between the host computer and connected servo drives. This arrangement lets the PC handle higher-level computing while the card manages time-critical motion control tasks. The board is identified as a CNC version without export restriction.

The card carries 1 MB RAM to store the real-time NC kernel and parameter tables, allowing quick retrieval during interpolation cycles. Within the rack, it can supervise up to 8 drives directly, and that limit can be expanded to 32 drives by cascading bus couplers. Its scheduling engine can track up to 7 processes at the same time, so tool changes, spindle positioning, and auxiliary axis tasks can run in parallel. A size of 17.5 × 124 × 280 mm keeps the module within a single PC slot and helps preserve airflow around adjacent hardware. It installs in an industrial PC that provides an ISA backplane and the required supply voltage.

Data retention is supported by a lithium buffer that provides 5000 h of backup, allowing the controller to restart with preserved offsets after shutdown. During mains loss, the circuitry writes volatile registers within a minimum power-fail save window of 8 ms, which helps prevent program corruption. The optical SERCOS channel tolerates up to 12.5 dB of link attenuation, and communication over the fiber-optic pair helps isolate the drive ring from electrical noise. A 50-way ribbon cable connects the onboard PLC port to an Indramat Local Bus coupler for the exchange of motion-related I/O signals.
