Product Description:
The CSH01.1C-CO-EN2-MEM-MA1-S2-S-NN-FW controller card is produced by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. Installed in an IndraDrive rack, it executes axis calculations, processes encoder feedback, and exchanges data with higher-level PLCs during coordinated machine operation. In packaging lines, material-handling cells, and test stands, it links motor sensors, analog references, and relay outputs so drives can follow commanded positions and respond to interlocks in real time. This arrangement supports repeatable motion sequences across multiple axes without requiring separate external signal-processing hardware for each function.
The card draws only 7.5 W from its logic rail, which helps limit panel heat during operation, and it can still boot quickly because startup inrush reaches 4 A. Network traffic moves over the CANopen/DeviceNet interface, allowing standardized messaging and control exchange without an added communication module. The En2 feedback connection supplies 5.0 VDC at up to 350 mA for EnDat 2.1, 1 Vpp, or 5 V TTL feedback devices, and it uses a termination of 35 ohms to help maintain signal quality on longer cable runs. This supports stable encoder communication while reducing the chance of signal distortion inside the drive system.
The MA1 analog expansion provides two inputs and two outputs, each using a range of ±10 V for reference and process signaling. Signal conversion is performed with 12-bit resolution, giving finer control over analog setpoints such as valve commands or torque references. The MEM counter channel processes incremental marker pulses up to 1 MHz, which supports precise electronic gearing between master and follower axes during synchronized motion. For switching external devices, the S2 relay is rated at 24 VDC and 1 A, allowing the controller to actuate brakes, contactors, or stack lights directly.
