Product Description:

The CSH01.1C-S3-ENS-NNN-MD2-L2-S-NN-FW is a drive controller section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive cabinet, the section coordinates motion commands, fieldbus communication, and local I/O so that servo axes follow programmed profiles within automated machinery. By combining encoder evaluation, analog interfacing, and network ports inside one module, it reduces panel wiring and gives the machine PLC direct access to real-time motor feedback.

The analog circuitry accepts command signals over a range of ±10 V, which lets external motion sources deliver velocity or torque setpoints with standard industrial voltage scaling. A typical input resistance of 160 kΩ minimizes loading on upstream signal generators, preserving signal fidelity across long cable runs. When the section must send a proportional signal back to a supervisory device, its analog output can source up to 1 mA, and each increment corresponds to 19.5 mV/inc, supporting fine trimming of analog speed references. For service access, the integrated RS-232 port handles point-to-point diagnostics up to 115 kBaud, providing a fallback channel when the primary network is unavailable.

The motion bus uses SERCOS III over a front-panel 8-pin RJ-45 connector, while a separate RJ12 socket supports synchronous serial SSI encoders up to 75 m at 500 kHz. The EnDat/1Vpp interface delivers power to distance measuring systems with a budget of 500 mA, and differential signals remain accurate along an encoder cable length of 75 m. Local machine signaling is handled by MD2 expansion lines that present 16 digital inputs and 16 digital outputs for limit switches, probes, or pneumatic valves. When an emergency stop is triggered, the certified safety layer invokes Safe Torque Off, immediately de-energizing the power stage without affecting communication pathways.
