Product Description:

The CSH01.2C-SE-ENS-NNN-CCD-L1-S-NN-FW is a plug-in control section manufactured by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed on the front of an IndraDrive power module, it provides the computational core that interprets motion commands, supervises axis status, and issues real-time drive signals. By combining signal processing, fieldbus interfacing, and safety monitoring in one compact card, it serves as the central coordinator for servo motors, actuators, and auxiliary I/O in automated assembly cells and material-handling machinery.

In continuous operation, the board’s electronics draw a base load of 8.5 W, easing thermal design for the surrounding cabinet. Drive communication occurs over SERCOS II, which carries cyclic setpoints and feedback with deterministic timing, while an additional connector supports SERCOS III for high-speed cross-communication between neighboring drives. At power-up, the circuitry can momentarily demand an inrush of 4 A, so the upstream supply should include appropriate surge capacity. The integrated feedback interface supplies encoders with a stabilized rail of 11.6 V and up to 500 mA; this output supports resolvers, optical encoders, or other devices that conform to the standard encoder evaluation profile, allowing direct connection without external regulators.

Hard-wired enable logic is routed through the L1 channel, which recognizes a permissive level of 24 V / 3 mA before drive functions become active. Command gating limits each incoming pulse to 100 ms, and position-capture inputs can sample at frequencies as high as 400 kHz, allowing precise synchronization with external sensors. A built-in starting lockout blocks torque generation after every power cycle until the controller receives valid enable signals. The stopping response is classified as Category 0, so supply energy is removed immediately when a stop is requested.
