Product Description:

The CSH01.1C-ET-ENS-EN2-NNN-S1-S-NN-FW is an advanced controller from Bosch Rexroth Indramat that belongs to the CSH Advanced Controllers series. Installed in a drive cabinet, it issues setpoints, gathers status data, and links feedback devices so that servo inverters and field I/O remain synchronized within an automated cell. By combining encoder evaluation, safety inputs, and Ethernet networking on one card, the unit serves as the real-time bridge between a plant-level PLC and the motion hardware on the machine floor.

Under nominal load, the controller draws 7.5 W, so only localized convection is needed to remove heat from the electronics. Command values can be sent through the analog channel; it sources up to 1 mA at a reference level of 5 V, which is sufficient for drive speed or torque references that demand low-current signaling. Digital sensing lines accept 3 mA, enabling direct connection of proximity switches without extra buffering. Network access is handled by a Multi-Ethernet interface, allowing the same hardware port to support different industrial protocols. A standard membrane control panel on the front edge provides parameter access and local diagnostics without the need for an external HMI.

For discrete actuators, one output stage can supply up to 500 mA, letting the board switch contactors or indicator lamps directly. High-resolution position feedback is supported by the secondary EN2 port, which clocks encoder signals at 1000 kHz while powering the sensor with 5.0 V at 350 mA. The main Ethernet PHY follows the 100Base-TX standard, ensuring deterministic traffic when the controller is integrated into a line topology. Safety channels are processed through Safety Technology I/O, allowing emergency-stop chains to be wired without separate relays. Additional supply rails deliver 11.6 V at 0.5 A for the ENS interface, and the controller also supports a Standard Encoder Evaluation port together with an EnDat 2.1 / 1 Vpp / 5 V TTL channel for primary feedback.
