Product Description:

The CSH01.3C-ET-EN2-NNN-CCD-L2-S-NN-FW control section is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. As a modular drive controller component, it hosts the processing, communication, and safety layers that coordinate IndraDrive power modules with external PLCs and field devices. In industrial automation, it delivers axis control, real-time networking, and integrated machine safety for packaging, handling, and assembly equipment. The unit installs into the IndraDrive power base and offers deterministic Ethernet channels for multi-axis synchronization.

Its analog interface accepts an input range of ±10 V, so external speed or torque commands can be wired directly. The input presents 160 kΩ of resistance, which minimizes loading on the source. A buffered analog output supplies up to 1 mA at 5 V for process monitoring. Digital traffic moves through the Multi-Ethernet module, and the cross-communication function operates as a master for cyclic data exchange among follower drives. Network connections are provided through 2 x RJ-45 100Base-TX ports that support line or star cabling. An encoder socket in D-Sub 15-pin format links sensors, and a 120 Ω termination matches RS-422 pairs. The board can source 350 mA at 5.0 V for encoder electronics.

Overall size is 241 × 103 × 49.5 mm, allowing the controller to share enclosure space with power modules on standard 50 mm grid rails. Position feedback is decoded through the EN2 interface, which supports BiSS-B or EnDAT 2.2 protocols for high-resolution motion loops. Drive-integrated functional safety is provided by Safe Torque Off. The STO channels sense a logic level from an external safety relay at DC 24 V while drawing 3 mA, and they interrupt gate firing within microseconds when the signal is removed. Acting as master, the control section propagates the stop command across the Multi-Ethernet backbone so follower axes enter a torque-free state simultaneously.
