Product Description:

The CSH02.1B-ET-EC-EC-S5-NN-NN-FW controller is manufactured by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. Designed for cabinet mounting, it provides axis processing, bus routing, and certified safety functions that coordinate servo drives and I/O modules in automated assembly cells, packaging equipment, and printing lines. Acting as the command node, it interprets encoder feedback, issues torque and position commands, and shares process data with higher-level PLCs over real-time Ethernet networks.

Multi-protocol connectivity is provided through the controller’s Multi-Ethernet interface, allowing on-the-fly selection between sercos III, EtherCAT, EtherNet/IP, PROFINET IO without hardware changes. Physical signaling complies with X25 P1 for the incoming EtherCAT line and X24 P2 for the outgoing daisy-chain, simplifying ring or line topologies. The internal electronics reserve a total EC supply budget of 6 W, while each add-on encoder interface draws no more than 1.1 W, keeping thermal dissipation within the convection limits of compact cabinets. Two encoder channels can be processed simultaneously, and the Extended Scope option adds oscilloscope-style trace functions for setup and diagnostics.

On the physical layer, the Ethernet transceivers meet the IEEE 802.3 standard, assuring automatic negotiation with common switches and diagnostic tools. The separate ET communication module consumes just 2.7 W, leaving capacity for the S5 safety board, which is allocated 2.5 W and connects through terminals X41, X42, and X43 while processing two additional encoder signals. For low-voltage auxiliaries, the controller sources up to 500 mA on both its 12 V and 5 V rails, which is enough for optical link converters or small sensors. Certified Safe Motion functionality supervises velocity, position, and stopping distance without external relays.
