Product Description:

The CSH01.1C-SE-EN1-EN2-MD1-NN-S-NN-FW control section belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. Installed next to a power stage, this module executes motion calculations, conditions feedback, and interfaces with higher-level PLCs inside automated cells. It supervises axis functions, distributes setpoints, and coordinates local expansion I/O while omitting integrated safety circuitry, making it a straightforward processing node for machines that already use external protective logic.

The analog front end digitizes ±10 V process signals within 10 µs conversion windows, and each sample is quantized at 19.5 mV per increment. This timing and resolution combination allows the drive regulator to follow rapidly changing command curves without visible quantization steps. Real-time traffic moves over SERCOS II, and the optical ring runs at 16 MBaud, so position words and status bits circulate with sub-millisecond latency between the controller, drives, and distributed sensors. The onboard logic, extension terminals, and sensor transceivers draw from a dedicated DC 24 V, 1.1 A rail, isolating them from high-power bus noise. Twelve digital inputs and eight transistor outputs can be added through a plug-in I/O extension, and their switching states may also be echoed by a relay contact rated for DC 24 V at 1 A.

Feedback resources are organized on two independent channels. Encoder port one provides 8 V excitation for resolver or HSF devices, while channel two furnishes 5 V to incremental or absolute transducers that communicate via EnDat 2.1, 1 Vpp, or 5 V TTL formats. Parameter access on the front of the card is carried out with a standard single-line control panel, and deeper diagnostics are available through the auxiliary RS-232 interface. STO or guard-locking functions are handled by the host controller.
