Product Description:

The CSH01.1C-PB-EN1-NNN-MD2-L1-S-NN-FW control section is manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. This plug-in module forms the command layer inside Rexroth drive stacks, where it conditions fieldbus data, processes feedback, and issues motion commands to connected power stages. In an industrial automation line, it serves as the local intelligence that synchronizes axes, converts sensor inputs, and relays status information to supervisory PLCs, allowing deterministic operation of packaging machines, material handling cells, and other electromechanical equipment. Because it is a plug-in module, it fits directly into compatible drive assemblies.

Primary supply power for the board is 24 V DC, with a quiescent draw of 7.5 W, so auxiliary supplies can be sized for a low continuous load. Two differential analog input channels present an impedance of 160 kΩ, minimizing loading on process transmitters, while the analog outputs change in discrete steps of 19.5 mV/inc, which supports fine current or speed references. All cyclic communications move through a PROFIBUS-DP interface that supports a data rate of 12 MBaud, enabling fast exchange of setpoints and diagnostic words between the controller and the plant network. This arrangement lets the module manage control signals and network traffic within the same drive platform.

At power-up, the module tolerates an inrush of 4 A without tripping upstream supplies, after which the digital logic and feedback circuits stabilize. The MD2 expansion on this variant adds 16 In / 16 Out discrete channels that can trigger sequence steps or report limit-switch states. Resolver feedback is accepted at 4 kHz carrier frequency and is energized by a dedicated 18.2 Vpp source, while the HSF encoder port receives its own 8 V DC supply and 0.2 A budget. Safety provisions include a 24 V / 3 mA lockout line with Stop Category 0 starting lockout, and serial feedback devices may be wired through an RJ12 six-pin SSI connector.
