Product Description:
The CSH01.1C-PB-EN2-NNN-NNN-NN-S-NN-FW is a modular drive and motion control card produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed inside the manufacturer’s IndraDrive servo inverters, this card executes axis calculations, handles fieldbus communication, and routes feedback, making it a central element for coordinated industrial automation tasks such as packaging, printing, and material handling. By combining programmable logic, high-resolution encoder processing, and integrated fieldbus connectivity, the unit provides deterministic command and diagnostic exchange between the drive system and higher-level machine controllers.
The card communicates with supervisory PLCs through PROFIBUS; its D-Sub 9-pin female connector follows the EIA-RS485 physical layer and supports automatic baud rate detection. Up to 11 digital inputs allow edge-triggered events such as limit switch states, while 4 digital outputs can energize contactors or signal status to peripheral devices. One analog input with an input resistance of 160 kΩ accepts ±10 V position or torque commands, and two analog outputs furnish reference signals. One of those outputs supplies a calibrated level of 5 V for sensor excitation, and relay contacts on the board can switch 24 V circuits at 1 A to isolate field wiring from the internal logic.
Analog source loading remains minimal because each output can deliver 1 mA without distortion. The integrated encoder interface supports EnDat 2.1 / 1 Vss / TTL, allowing the drive to accept absolute, sine-cosine, or incremental feedback without additional modules. For cabinet layout, the board has a width of 49.5 mm, a depth of 103 mm, and a height of 241 mm, allowing it to fit alongside IndraDrive power sections within a 300 mm deep enclosure. The spacing also accommodates the PROFIBUS connector and maintains airflow between neighboring units so the microprocessor and gate-array circuitry can operate within the ambient temperature range used for the series.
