Product Description:

The CSH01.1C-PL-EN1-EN2-NNN-L1-S-NN-FW controller is manufactured by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. It is installed in industrial automation cabinets to coordinate discrete I/O, encoder feedback, and safety interlocks between motion axes and supervisory control equipment. Using its parallel and serial links, the module forms a compact interface layer between drive electronics and the machine PLC, which helps local signal handling remain organized inside the control cabinet.

The unit communicates with field devices through a parallel interface, providing 16 digital inputs for status acquisition and 16 digital outputs for command signals. The primary encoder line is energized at 8 V, and it supports resolver and HSF feedback devices. The resolver carrier runs at 4 kHz while the excitation amplitude measures 18.2 Vpp, helping the controller process stable position information in electrically noisy enclosures. A D-Sub 9 female connector carries the dedicated safety circuit, which simplifies wiring of the cabinet interlock loop. Input sampling and output switching occur synchronously, so machine events that require deterministic response can be handled locally rather than waiting for backplane bus cycles.

Parameter data is accessed through RS232, which supports direct point-to-point communication for setup and diagnostics. The integrated safety function, Starting Lockout, is driven by a control input that accepts 24 V / 3 mA, preventing uncommanded drive enable until external conditions are met. Secondary feedback channels supply encoders with 5 V and accommodate EnDat 2.1, incremental 1 Vpp, or 5 V TTL signals. This path tolerates loads down to 35 Ω and can source up to 350 mA, allowing an auxiliary position sensor to be monitored without interfering with the primary resolver loop.
