Product Description:

The CSH01.1C-ET-ENS-EN2-MD1-L2-S-NN-FW control section is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted inside an IndraDrive unit, it supplies axis control, field networking, and encoder processing for servo machinery. By turning fieldbus commands into precise torque, speed, and position references, the board coordinates motion in packaging, printing, and material-handling systems while supervising feedback and safety functions.

The analog front end accepts a range of ±10 V, and the associated input path presents a resistance of 160 kΩ, so connected sensors experience minimal loading while still delivering full-scale references. When the board must generate process signals, it sources up to 1 mA at a calibrated 5 V level. For discrete control, the MD1 plug supports twelve digital inputs and eight digital outputs, allowing local interlocks without PLC latency. Secondary encoder electronics are powered from the EN2 rail, which delivers up to 350 mA at 5 V to incremental or absolute transducers tied to the second feedback port. Encoder interface 1 accommodates IndraDyn, Hiperface, 1 Vpp, and TTL feedback, whereas encoder interface 2 handles EnDat 2.1 along with the same analog or digital formats. Data exchange to higher-level controllers is routed through the ET interface, which complies with 100Base-TX Fast Ethernet standards and terminates on an RJ-45 8-pin connector.

Complementing the EN2 line, a dedicated ENS sensor supply provides 12 V for external proximity switches or light curtains. Parameter access and basic diagnostics are handled directly on the Standard Control Panel mounted on the drive face, so routine setup can be done without auxiliary tools. Network flexibility stems from the MultiEthernet master stack, which can be configured for several protocol profiles without hardware changes. For risk reduction, the board implements the certified Safe Torque Off function, which removes drive energy rapidly when the safety channel is asserted.
