Product Description:

The CSH01.1C-NN-EN2-EN2-NNN-S1-S-NN-FW is a motion-logic controller card produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in modular drive racks, the card coordinates servo axes, processes feedback from integrated encoders, and exchanges data with higher-level PLCs. Within a drive system, it acts as the real-time interface between application software and the connected power stage, enabling deterministic position, velocity, and torque commands in packaging, printing, and electronic assembly equipment. This arrangement lets the rack execute closed-loop motion tasks locally instead of relying on slower supervisory timing.

Heatsinking requirements are modest because the board dissipates only 7.5 W as base power, while each optional EN2 module adds a further 6 W. Analog control loops can be tuned with a resolution of 19.5 mV/inc, which is the smallest step the ±10 V output can generate for a servo amplifier. The controller has 2 independent encoder ports and can evaluate dual feedback sources for synchronized or redundant operation. Each port accepts the mixed-protocol format EnDat 2.1, 1 Vpp, 5 V TTL, so the card can work with either absolute or incremental transducers without additional interface hardware.

To support those feedback links, the controller offers a stabilized 5 V supply rail that can be routed to sensor heads over distances as long as 75 m when shielded cable is used. During power-on, the logic draws an inrush of 4 A for 100 ms before settling to its nominal consumption, so the supply must be sized accordingly. Integrated safety terminals require a dedicated 24 V DC feed and use the same source to handle emergency-stop chains and protective door switches through onboard inputs and outputs. This separation helps keep protective circuits independent from normal motion commands during machine operation.
