Product Description:

The CSH01.1C-PB-EN2-NNN-NNN-L1-S-NN-FW is a single-axis motion logic controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. The unit coordinates drive, I/O, and safety tasks in industrial automation cells, acting as the control section that plugs into Rexroth power sections to form a complete servo drive. By combining fieldbus communication and encoder evaluation on one compact board, it supports deterministic positioning and diagnostic reporting in assembly machines, packaging lines, and material-handling systems.

Its logic receives an acknowledgment supply of 24 V / 1 A, which allows the controller to signal ready status even when the main power bus is off. Drive commands are exchanged over PROFIBUS-DP, and the bus electronics are isolated from the CPU while an external 24 V digital I/O supply keeps sensor lines at the same potential as the machine wiring. Parameter access through the front standard control panel is supplemented by a service port that uses RS232 for point-to-point diagnostics. The EN2 slot is populated, and that encoder extension draws only 6 W while supporting EnDat 2.1 / 1 Vpp / 5 V TTL feedback for absolute and incremental transducers. The second and third encoder ports are not installed, which reduces unused connection points.

Functional safety is handled by a hardware starting-lockout circuit, and the feature is identified as Starting Lockout. The safety interface is wired through a 9-pole female D-Sub connector, and the lockout channel monitors a 24 V / 3 mA control signal before drive enable is released. Nonvolatile data and parameter sets can be stored on a MultiMediaCard, so saved controller data remains available after power is removed. Both the PROFIBUS communication board and the L1 I/O extension each consume only 2 W, which helps keep cabinet thermal load low during operation.
