Product Description:

The CSH01.1C-CO-ENS-EN2-MEM-L2-S-NN-FW is a plug-in control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Integrated into an IndraDrive power stage, it acts as the motion processor for a single servo channel and forwards status data to supervisory automation systems. The module is used whenever precise speed, position, and safety coordination is needed in packaging lines, material-handling axes, and general machine tools.

Hardware capability centers on motion control for 1 axis, supplied through the X60 connector. The board operates from a control supply of DC 24 V and charges its internal capacitors with an inrush of 4 A. Field communication is handled by CANopen and DeviceNet networks, while maintenance laptops connect through the dedicated RS232 serial interface. For feedback translation, the controller provides galvanically isolated absolute and incremental encoder emulation, which eliminates common-ground loops and does not require separate emulation power. Physical encoder ports accept IndraDyn, HIPERFACE, or 1 Vpp signals on Interface 1 and EnDat 2.1, 1 Vpp, or 5 V TTL on Interface 2. Without remote sense conductors, the EN2 channel supports cable runs up to 50 m.

Functional safety is implemented through the Safe Torque Off circuit, wired on a D-Sub 9-pin female connector beside the drive edge. When sense lines are used, the EN2 channel length extends to 75 m, and the controller reproduces encoder pulses with widths down to 100 ms for legacy devices. All differential signals are galvanically isolated to prevent crosstalk between drive and control racks, and the board supports encoder simulation on both interfaces simultaneously. The arrangement of two separate encoder interfaces lets the drive handle mixed feedback schemes, and the galvanic isolation maintains signal integrity over long cables inside large automated cells.
