Product Description:

The CSH01.1C-S3-EN1-NNN-MEM-NN-S-NN-FW control section is produced by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. Mounted on an IndraDrive drive stack, the module converts networked motion commands into precise axis signals and acts as the central logic component in packaging lines, pick-and-place gantries, and other automated machinery. It accepts encoder feedback and generates both digital and analog outputs so the surrounding drive topology can close position, speed, and torque loops with minimal latency. The unit also coordinates signal exchange between the higher-level automation system and the connected power section during normal axis operation.

It communicates with neighboring drive sections over the real-time optical bus, while its field-level connection to the automation host uses SERCOS III. For diagnostics and parameter transfer, the controller also presents a standard Ethernet service port that supports 100Base-TX signaling through a shielded 8-pin RJ-45 jack. Analog process values leave the board with an output resolution of 8-bit, and each increment corresponds to 19.5 mV/inc, allowing low-level voltage references for proportional valves or external amplifiers. Two probe inputs capture fast position triggers, and the encoder interface accepts both resolver and HSF feedback while supplying the transducer with 8 V. A 4 A inrush current limiter protects the internal rails at power-up, and the onboard relay can switch up to 1 A at 30 VDC for ancillary functions.

The emulation section reproduces absolute position data in SSI format, pushing clock pulses at a rate of 1 MHz with a drive capability of 20 mA. This signal can be transported over cables up to 40 m without repeaters, which allows flexible cabinet placement relative to moving axes. Base power consumption of the electronics is only 7.5 W, so thermal load on the enclosure remains low during continuous operation. SSI emulation also supports external devices that require absolute position data from the drive without adding a separate signal conversion module.
