Product Description:

The CSH01.1C-NN-ENS-NNN-NNN-NN-S-XP-FW is a controller section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in a Rexroth drive stack, it executes current, velocity, and position loops for servo axes and provides the interface between the power stage and higher-level PLCs or PCs. By coordinating feedback, digital I/O, and analog command signals, the module enables deterministic motion sequences in automated assembly lines, packaging systems, and material-handling equipment. It also manages the signal flow needed for responsive axis control when machine loads or commanded positions change during operation.

An analog input resistance of 160 kΩ minimizes loading on external sensors, and each input step is resolved to 1.23 mV/inc. Command values leaving the card are generated with 19.5 mV/inc granularity on the analog outputs, which supports fine speed adjustment at the drive. The current control loop closes every 125 µs, so torque commands are updated very quickly during dynamic motion. Logic inputs reach the ON state at 15 V, matching standard 24 V field wiring while rejecting lower-level electrical noise. The RS232 port supports local setup over cable lengths up to 15 meters, and the output group can source 1000 mA for light indicators or relays without an external supply.

Up to 500 mA is available for digital outputs and for powering incremental or absolute encoders. The probe function reacts to edge events within 4 µs, which suits precise registration tasks such as print mark detection. Feedback signals enter through a 15-pin D-Sub female connector and are digitized with a 12-bit converter, while carrier frequencies may reach 400 kHz. The encoder rail supplies 11.6 V to preserve signal quality over long cables, and output transistors can switch up to 8 kHz while relay contacts carry 1 A for hard-wired safety chains.
