Product Description:

The CSH01.1C-S3-ENS-EN2-MA1-S2-S-XP-FW is a motion-control logic unit from Bosch Rexroth Indramat that belongs to the CSH Advanced Controllers series. It is installed in multi-axis IndraDrive systems where it coordinates servo amplifiers, encoder feedback, and safety functions to execute deterministic positioning tasks on automated machinery and material-handling cells. By handling command processing and feedback evaluation in one control section, the unit helps connected axes respond in a coordinated and repeatable manner during synchronized machine movement.

The controller draws a base power of 7.5 W from a control circuit that must be fed with DC 24 V. This low consumption supports dense cabinet layouts without adding excessive heat to surrounding components. A typical inrush of 4 A occurs when the internal capacitors charge, so the supply must tolerate short startup surges. Real-time communication with drives and PLCs is handled through the SERCOS III module, providing cyclical data exchange over Ethernet hardware for synchronized axis updates. Two differential analog inputs and two analog outputs each accept ±10 V signals at 12-bit resolution, allowing the controller to exchange speed or torque references with external control equipment. Safe Motion technology supervises velocity limits and shutdown paths so the drive can be integrated into safety chains.

Encoder channel EN2 supports EnDat 2.1, 1 Vpp, and 5 V TTL formats and is terminated internally with 35 ohms to maintain signal integrity. Channel ENS powers IndraDyn or HIPERFACE sensors with a regulated 11.6 V supply, and time-critical position latching is supported because the controller accepts pulses as wide as 100 ms. Network wiring is made through an RJ-45 (8-pin) connector that operates on the 100Base-TX Ethernet layer, allowing the module to use standard industrial cabling. The single-line panel display reports axis status, and because hot-plug capability is not supported, the keypad must be connected only when the drive is de-energized. Encoder feedback, analog signal exchange, and network communication are handled through separate onboard interfaces.
