Product Description:

The MTS-P02.2-D4-P1-S4-NN-NN-FW servo control module is produced by Bosch Rexroth Indramat and belongs to the MTS Servo Control Modules series. It functions as an embedded motion controller that bridges fieldbus networks, operator interfaces, and drive electronics in automated machinery. By mounting into an ISA backplane, it coordinates axis commands, transfers diagnostic data, and supplies communication pathways between higher-level PCs and individual drives. This arrangement lets the module serve as a central control layer for coordinated motion across multiple connected devices.

In mechanical terms, the card measures 295 mm deep, 22 mm wide, and 145 mm high, so it occupies a single slot while still providing ample board area for signal conditioning. The host connection uses the ISA bus, allowing direct memory-mapped access to parameters and motion registers. Two RS232 ports and two RS422/485 ports share a common communication stack through the selectable RS232/RS422/RS485 multi-protocol interface, while a PROFIBUS-DP master port exchanges cyclic data at up to 12 Mbaud. The PROFIBUS section draws 650 mA, and the separate serial board consumes 250 mA, so backplane power planning is straightforward. Logic electronics absorb a peak of 1.8 A from the +5 V rail, and an auxiliary PC/104 header can pull 2.5 A to supply mezzanine I/O or specialized motion coprocessors. This combination allows the module to support both serial equipment and networked field devices from the same control platform.

System expandability includes support for 4 operator panels on the BT bus and space for 4 modules on the PC/104 stack, enabling customized operator interfaces and local signal expansion without replacing the base controller. Each serial channel buffers messages in a 256-byte hardware FIFO, reducing interrupt load when multiple axes transmit status frames. Separate buffering on each channel helps maintain steady communication when several devices send alarms, position data, or operating values at the same time. The backplane distributes +5 V, +12 V, -12 V through stabilized rails so analog reference circuits, logic, and transceivers receive the correct voltage domains, while the 250 mA serial section current keeps overall thermal dissipation within enclosure limits.
