Product Description:

The CSH01.3C-NN-EN1-NNN-CCD-L2-S-NN-FW module is an advanced motion-control card manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in a Rexroth drive stack, it handles signal conditioning, network traffic, and real-time logic. This keeps command timing consistent across linked axes. Servo amplifiers therefore receive deterministic commands during positioning, speed, or torque loops in automated production equipment.

The analog front end presents 160 kΩ of input resistance, allowing sensors to drive an input span of ±10 V without loading errors. For outbound process variables, the card sources up to 1 mA at a calibrated level of 5 V. Two cross-communication connectors link neighboring drives, and messaging follows the IEEE 802.3 protocol over the 100Base-TX engineering standard for deterministic peer exchange. Four on-board digital outputs can each switch 0.5 A, while the input side can accommodate eleven discrete channels that report machine states such as limit switches or interlocks. Together, these analog, digital, and Ethernet resources consolidate local process feedback so higher-level PLCs exchange only essential data.

During power-up, the card draws an inrush current of 4 A that lasts roughly 100 ms; after that surge, typical consumption stabilizes at 8.5 W. The encoder supply labeled EN1 delivers 18.2 Vpp at 4 kHz, providing isolated excitation for SinCos feedback devices without external regulators. Internal logic also supervises two cross-comm ports so that a cable break is detected before axis coordination is lost. The integrated safety layer supports Safe Torque Off, enabling drive outputs to be electrically inhibited without removing main power, which is common in modern cells where manual intervention occurs near moving axes.
