Product Description:

The CSH02.1B-CC-EC-PB-S4-EM-NN-FW is an automation controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It serves as the central processing section in multi-axis drive cabinets. It translates machine program instructions into synchronized motion commands and fieldbus traffic for conveyors, robots, and packaging stations.

During operation, the module draws a base power of 17 W from a control supply rated at DC 24 V. Command and diagnostic data are exchanged with downstream drives over a SERCOS III master interface, while higher-level PLCs or HMIs can access the same process image through the PROFIBUS-DP channel. Position feedback is accepted through a multi-encoder interface; it provides 12 V and 5 V encoder rails, each able to source 500 mA, and supports absolute SSI as well as incremental formats so one board can process different transducer types. Emulation logic reproduces both absolute and incremental signals for devices that lack direct encoder wiring. Physical-layer requirements for the PROFIBUS port follow the EIA-RS485 standard, and an optional repeater output can supply 5 V ±10% at up to 75 mA to an external line amplifier.

The controller’s maximum configured demand reaches 22.9 W, a value that helps size cabinet power supplies when all encoder feeds and communication links are active. Integrated Safe Motion technology enables certified stop, limit, and speed functions without separate safety relays, which reduces wiring complexity. The encoder supply budget of 6 W limits the total current available for multiple feedback devices and protects the onboard regulators. Shielded encoder-motor cables can run up to 40 m maximum, while the limit with unshielded cable is 30 m. An emulation cable-length check helps prevent signal degradation when absolute and incremental outputs are recreated.
