Product Description:

The CSH01.1C-PB-EN2-EN2-NNN-S2-S-NN-FW is an automation controller produced by Bosch Rexroth Indramat and assigned to the CSH Advanced Controllers series. It supervises one motor drive, interpreting motion commands and relaying feedback between the drive and the higher-level control system. In a plant network, the unit executes axis regulation, manages fieldbus communication, and routes encoder data so that positioning accuracy is maintained during real-time operation.

The controller’s primary network interface is PROFIBUS, and messages are exchanged at up to 12 MBaud, allowing deterministic communication with PLCs in distributed installations. It is engineered for a single-axis topology, which keeps processing resources focused on one drive channel. Position feedback is brought in through two encoder tracks, and the controller has 2 encoder channels. Supported signal formats include EnDat 2.1 / 1 Vpp / 5 V TTL, so both absolute and incremental feedback devices can be connected. The incoming lines see an encoder load resistance of 35 Ω, and power for the sensors is provided on two rails: 5.1 V without sense and 5.0 V when sense leads are used. A Mini-DIN 8-pin connector carries the RS-232 service port, and this link functions over cable runs up to 15 m for local access when fieldbus communication is unavailable.

The encoder supply budget reaches 350 mA, which covers most optical and magnetic transducers without external power taps. For diagnostics, the serial port can stream trace data at 115 kBaud. Integrated safety I/O is rated for 24 V logic, and the solid-state outputs switch up to 24 V / 0.5 A while relay contacts permit DC 24 V at 1 A for hard-wired emergency chains. These resources are coordinated by the controller’s Safe Motion technology, enabling certified stop and speed-limited modes through the integrated safety functions.
