Product Description:

The CSH01.1C-ET-EN2-EN2-MEM-S2-S-NN-FW controller is produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It acts as the central motion and I/O processor for modular drive packages, coordinating axis control through integrated fieldbus and encoder channels. In an automation cell it converts high-level machine commands into deterministic drive signals, allowing precise position, velocity, and safety functions to be executed by connected power sections.

During operation the unit draws a base power of 7.5 W, an important figure for panel thermal budgeting in multi-axis cabinets. Command data reach the controller via the Multi-Ethernet interface, and the embedded switch supports the 100Base-TX standard so standard CAT5e plant cabling can be used. At start-up the electronics can demand a peak of 4 A; fuses and supplies must tolerate this inrush to prevent nuisance trips. Two motor feedback ports accept 2 x EnDat 2.1 / 1 Vpp / 5 V TTL signals, while a regulated 5 V rail powers the sensors and incremental encoders connected to those ports. Serial diagnosis remains available through an RS-232 link that can extend 15 m and operate at 115 kBaud for legacy devices.

For drive systems requiring encoder simulation, the controller can generate line-driver outputs up to 1 MHz, supporting absolute or incremental formats over distances to 40 m without signal conditioning. When bridging to downstream axes over the En2 ports, cable limits vary: installations without feedback sense lines can run 50 m, whereas shielded leads with sense pairs reach 75 m before attenuation affects timing. The pulse train width is limited to 100 ms, letting high-resolution position strobes remain accurate across the network. Functional safety is built in through the Safe Motion architecture, and related I/O terminates on a D-Sub 9-pin female connector to form a hard-wired safety chain with emergency stop and enable signals.
