Product Description:

The CSH01.1C-ET-ENS-NNN-MA1-NN-S-NN-FW is a control section built by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive modular stack, it governs a single servo axis by converting network commands and encoder feedback into drive-level signals that shape motor torque, speed, and position. Within an automation cell, this module links higher-level PLCs to the power section and acts as the local processor that times motion sequences, supervises safety states, and publishes diagnostic data to the plant network.

The controller’s base electronics draw only 7.5 W, so cabinet thermal load is minimal even during continuous operation. It exchanges real-time data through a Multi-Ethernet platform that automatically switches between the supported industrial protocols. Two independent copper channels are provided, and the backplane routes traffic through 2 Ethernet ports that accept line or ring topologies. Each channel follows the 100Base-TX standard, enabling deterministic 100 Mbit/s transfer for motion profiles and status words. Physical connection is achieved with a ruggedized RJ-45, 8-pin jack, allowing premade shielded patch cables to be used without special tools.

The front panel hosts a D-Sub connector that powers and reads incremental or absolute transducers. The encoder supply delivers up to 500 mA at a regulated 11.6 VDC, so high-resolution feedback devices remain stable across long cable runs. The MA1 option card adds two differential analog inputs and two analog outputs, and each conversion stage resolves signals with 12-bit granularity across a ±10 V span, letting the drive accept speed-trim commands or report process variables. During power-up, the unit momentarily draws a typical inrush of 4 A, a value that informs circuit breaker sizing and cabinet wire gauge.
