Product Description:

The CSH02.1B-CC-EC-EC-S4-DA-NN-FW is a programmable motion control unit built by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed inside an IndraDrive cabinet, it serves as the command layer for servo infeed and auxiliary actuators along one mechanical axis. It manages the position, velocity, and torque loops required in pick-and-place stations, presses, and packaging equipment. It can coordinate drive behavior and machine responses from one compact control location inside the cabinet.

At its core, the unit is intended for a single-axis drive and draws a baseline of 17 W from a DC 24 V supply. Motion commands and diagnostic data travel through a SERCOS III master interface, allowing tightly synchronized communication with connected inverters. The integrated DA option card samples process variables with 14-bit resolution, which supports fine force or tension regulation. Both front-panel encoder ports accept multiple feedback formats, so EnDat, SSI, or incremental devices can be connected without separate interface boards. This arrangement also reduces the number of add-on modules required for mixed feedback layouts. Low standby losses help limit heat inside compact fanless cabinets.

The DA analog output supports a capacitive load up to 100 nF and a resistive load of 2 kΩ. Incoming 20 mA loops see an internal resistance of 300 Ω, which keeps the expected voltage drop consistent for connected sensors. Each EC expansion inserted beside the base module adds 1.1 W to the total power draw, while the S4 safety board adds more consumption and enables Safe Motion monitoring. Two safe inputs and two safe outputs support hardwired safety functions such as STO, SS1, or SOS. Resolver feedback is not supported, so position signals must come through the dual multi-encoder ports.
