Product Description:

The CSH01.1C-ET-NNN-NNN-MA1-L2-S-NN-FW is a single-axis motion and logic controller manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It functions as the central processor that links servo drives, field devices, and supervisory systems inside automated machinery. By combining fast program execution with integrated network interfaces, the unit coordinates position loops, handles real-time diagnostics, and supplies the enabling signals required for Safe Torque Off on connected drives. It is typically installed in cabinet-mounted drive stacks and provides deterministic communication over Ethernet and serial channels so that actuators, sensors, and human-machine interfaces share a common control core.

At idle the controller draws just 7.5 W, a figure that limits cabinet heat when the axes are disabled. Network traffic is handled by the Multi-Ethernet interface, which supports the 100Base-TX physical layer. The ET option card consumes an additional 2.2 W when active, so power budgeting can be completed without derating the upstream 24 V supply. A dedicated L2 diagnostic port is provided through a D-Sub, 9-pin female connector for drive-to-drive data exchange or parameter cloning. For serial integration, the RS-232 channel accepts data rates up to 115 kBaud. The MA1 analog module presents two inputs and two outputs; the inputs accept signals within ±10 V, are filtered to 1 kHz, and exhibit an impedance of 1000 kΩ to minimize sensor loading.

The analog outputs can source up to 10 mA and are designed for loads down to 1 kΩ, enabling direct connection to proportional valves or reference inputs on third-party drives. Their consumption is limited to the MA1 module’s 2 W budget, which eases thermal planning for densely populated racks. When Ethernet wiring is required outside the cabinet, the transceiver maintains reliable signaling over copper runs reaching 100 m. Application safety is reinforced by the integrated Safe Torque Off circuit, while the controller manages motion sequencing, feedback monitoring, and shutdown functions from a single slot in an IndraDrive system.
