Product Description:

The Bosch Rexroth Indramat CSH01.1C-PL-ENS-EN2-MD1-L1-S-NN-FW is a single-axis control section from the CSH Advanced Controllers series. Installed in the drive stack, the module interprets encoder feedback, supervises I/O, and issues real-time command values to downstream power sections. By handling these deterministic tasks, it supports precise motion sequences, coordinated stop functions, and diagnostic reporting in production lines, packaging cells, and other automated machinery that depend on rapid closed-loop servo regulation.

Its internal electronics draw a baseline of 7.5 W, which helps limit cabinet heat while still supporting sixteen programmable logic inputs and sixteen complementary outputs for machine signals. Command data are exchanged through a Parallel Interface, which reduces bus latency when multiple axes share position data. The second encoder channel can process EnDat 2.1 / 1 Vpp / 5 V TTL formats, so incremental or absolute sensors can be used without external converters. When line power is applied, the controller draws an inrush current of 4 A for up to 100 ms, so upstream circuit protection must tolerate this brief startup demand. Two analog monitor signals are also available in 1 mA current and 5 V voltage ranges for drive diagnostics.

The first encoder port uses a D-Sub 15 female connector and supplies DC 12 V, while the secondary port supplies feedback devices with DC 5 V. The MD1 terminal block provides 12 digital inputs and eight transistor outputs for safety-related interlocks, and forced shutdown is handled as Stop Category 0 by the starting lockout function. Each relay contact on the board can switch loads up to DC 24 V / 1 A, which allows direct actuation of brakes or contactors without an auxiliary interface. This layout helps keep control wiring organized in larger panels.
