Product Description:

The CSH01.1C-S3-ENS-NNN-NNN-L1-S-NN-FW controller belongs to the CSH Advanced Controllers series produced by Bosch Rexroth Indramat. It occupies the command slot of an IndraDrive system and converts machine-level set points into real-time motion directives for servo axes in industrial automation cells. Within a multi-axis rack, the module supervises interpolation tasks, manages encoder feedback distribution, and forwards acknowledged status signals to overarching PLCs.

Its analog I/O stage accepts process references through a bandwidth of 1.4 kHz; the associated input path presents an impedance of 160 kΩ, which minimizes loading of delicate transducers. Quantization is handled at 1.23 mV/inc so small voltage changes are captured before being filtered by the firmware. The board supplies reference outputs: each channel can source up to 1 mA into a load as low as 5 kΩ, with delivered voltage maintained at 5 V. Outgoing signals are written in 19.5 mV increments, matching typical drive resolution. This step size supports fine closed-loop tuning during positioning routines. An acknowledgment circuit draws 1 A to reset fault latches after a safe stop.

Communication with higher-level controllers is carried on the real-time Ethernet channel specified as SERCOS III, while legacy parameter access remains possible through an RS-232 maintenance port that supports cables up to 15 m and baud rates to 115 kBaud. Incremental and absolute encoders receive a stabilized supply of 12 V directly from the card, eliminating the need for external regulators. The safety domain completes the feature set; its input circuits monitor emergency-stop lines at 3 mA and 24 V, and the dedicated safety I/O bus is rated for 1.1 A, letting designers integrate light curtains or door interlocks without additional relays.
