Product Description:
The CSH01.1C-NN-ENS-NNN-MA1-S2-S-NN-FW is a drive controller section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive power module, it supervises axis motion, processes feedback, and enforces Safe Motion functions in industrial automation cells. The board carries no fieldbus option, so the communication slot is not equipped and integration is handled through the drive’s native interfaces instead. By concentrating command logic and signal conditioning in one plug-in card, it streamlines cabinet wiring and supports coordinated control across multiple axes.
The analog input stage presents 160 kΩ of resistance, minimizing loading on potentiometers or process transducers. Discrete sensor terminals accept 24 V / 3 mA, while transistor outputs deliver 24 V / 0.5 A for pilot loads such as relays. On-board electronics draw only 7.5 W, which helps limit thermal dissipation inside the drive rack. This low electrical demand supports dense multi-axis installations without the need for additional cooling hardware. Motion feedback is sampled at a converter width of 12-bit, and the Standard Encoder Evaluation interface allows incremental or absolute encoders to be connected without extra adapters.
The card returns reference values through a 5 V / 1 mA analog output and supplies transducers with 11.6 V / 500 mA to power their electronics. Measurement of probe events is time-stamped to 1 µs, supporting precise spindle or tool synchronization during fast machine cycles. A Form-C relay rated at DC 24 V / 1 A is provided for functions such as brake release or ready signaling. The MA1 analog I/O extension adds two input and two output channels, allowing auxiliary process variables to be monitored and controlled directly from the controller. This arrangement expands signal handling without requiring a separate external interface card.
