Product Description:
The MTS-R02.2-M2-B1-NN-NN-FW is a servo control module produced by Bosch Rexroth Indramat within the MTS Servo Control Modules series. It serves as the master for an INTERBUS-S fieldbus segment, coordinating distributed I/O and drive nodes in automated machinery. Integrated communication ports and onboard logic process sensor states and motion commands so higher-level PLCs can offload real-time traffic. The module acts as a bridge between drive amplifiers, peripheral actuators, and serial networks.
The module occupies two slots in an Indramat multiaxis rack, and its enclosure measures 150 mm deep, 83.7 mm wide, and 192 mm high, allowing dense stacking without obstructing airflow. A regulated input of 24 VDC powers the internal logic, and continuous consumption remains below 0.7 A, which simplifies cabinet power sizing. For troubleshooting, an RS232C diagnostic port delivers ASCII status strings, while the master INTERBUS-S connector handles station addressing and baud-rate selection. Downstream devices connect through a galvanically isolated two-line RS422 remote bus, maintaining signal integrity across cabinet wiring. These interfaces support parameter uploads, diagnostics, and cyclic process data exchange while the module remains installed.
As a network master, the controller can supervise up to 256 fully addressed bus segments and a cumulative total of 512 user stations, making it suitable for large cells that share a single fieldbus hierarchy. Process data from every node is copied into a dual-ported RAM image that tops out at 512 bytes, giving the PLC a deterministic snapshot during each bus cycle. The internal I/O backplane can supply 2.2 A at 24 V and 3.0 A at 5 V, limited to 52 W of total power so daughter cards draw from a centralized source rather than individual supplies. An IP20 housing classification indicates finger-safe terminals and protection against solid debris larger than 12 mm, which suits closed electrical enclosures with low ambient contamination.
