Product Description:

The CSH01.1C-PL-EN1-EN1-MA1-S1-S-NN-FW is a controller section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted inside an IndraDrive rack, it acts as the central processor that links motion axes with machine-level inputs, encoder feedback, and integrated safety hardware. The module converts field signals and issues deterministic drive commands, so it is used in packaging lines, robotics cells, and material-handling stations that demand tightly synchronized multi-axis movement. By combining these control tasks in one section, it supports coordinated axis behavior without requiring separate interface modules for every signal path.

The module carries an analog I/O extension that supplies 2 inputs / 2 outputs auxiliary channels. Each channel operates across a voltage span of ±10 V, allowing direct connection to torque, pressure, or position transducers without external signal conditioning. Conversion accuracy on these auxiliary lines is 12-bit, matching the resolution provided by the EN1 A/D converter for incremental encoder signals. Discrete machine status is handled through the embedded parallel field bus that offers 16 inputs / 16 outputs points and exchanges cyclic data with the drive through the controller’s Parallel Interface master link. This arrangement allows the section to process analog feedback and binary machine states at the same time during interpolated motion.

Feedback and safety functions are managed on dedicated supplies. The HSF encoder ports deliver 8 VDC sensor power, while the resolver channel provides 18.2 Vpp, enabling HSF, RSF, or resolver devices to be assigned as primary and secondary encoders. Functional safety is implemented through the Safety Technology I/O option: the guard circuit accepts a safety input of 24 V at 3 mA, energizes a solid-state output rated 24 V / 0.5 A, and can release a redundant safety relay rated 24 VDC at 1 A when a stop is requested. Configuration and diagnostics are handled through the RS232 serial interface, which provides a simple point-to-point link for parameter upload and runtime trace data.
