Product Description:

The CSH01.1C-SE-EN2-EN1-NNN-NN-S-NN-FW is an electronics module manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed inside an IndraDrive power rack, this control section converts fieldbus telegrams and encoder feedback into motion commands that regulate torque, speed, and position. It is used in packaging, material-handling, and assembly stations where coordinated multi-axis movement and integrated safety monitoring are required. Because the control section sits in the rack, machine-level commands can be translated into axis-level responses with minimal delay. The control electronics handle interpolation, error handling, and parameter storage directly on the card.

To interface with analog transducers, the board provides an 1.4 kHz input bandwidth and 160 kΩ of input resistance, so changing sensor voltages are read without heavily loading the source. The output stage supplies reference signals at 5 V with a maximum drive current of 1 mA. Internal losses remain low because the unit dissipates only 7.5 W while operating from a 24 V DC control rail. For discrete inputs, each channel remains in the off state when line potential stays at 5 V or below, which helps prevent false switching from noise on long cable runs.

Command exchange occurs over SERCOS II, which keeps timing deterministic between the controller and the drive system. A channel is recognized as active once the line reaches 15 V, and the sinking output drivers can deliver up to 500 mA for devices such as relays or brakes. The first feedback port accepts EnDat 2.1 / 1 Vpp / 5 V TTL, while the second port supports resolver or HSF signals. The resolver carrier operates at 4 kHz with an amplitude of 18.2 Vpp, and the auxiliary encoder supply provides 5.0 V DC at 350 mA for connected feedback devices.
