Product Description:

The CSH01.1C-C0-EN2-NNN-NNN-S2-S-NN-FW is a modular control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed inside IndraDrive power units, it coordinates axis functions for industrial automation cells and material-handling stations that rely on synchronized servo motion. It also manages fieldbus traffic so connected equipment can exchange motion-related data with the drive during operation.

This controller draws a basic idle load of 7.5 W, so cabinet power budgets remain low even when multiple sections are used. It exchanges process data through the CANopen / DeviceNet interface, supporting deterministic cyclic telegrams for speed and torque commands. Motor feedback enters through an encoder port that accepts EnDat 2.1, 1 Vpp, or 5 V TTL signals, allowing mixed feedback topologies on a single machine. The Co plug carries logic lines over a five-pole arrangement that terminates in a Spring Terminal block, eliminating crimp contacts at the terminal point. An auxiliary 1 W Co module supply powers opto-isolated inputs, while the En2 option card is keyed by a D-Sub 15-Pin connector and dissipates 6 W under full encoder load. That card receives its logic rail from a regulated 5.0 V source derived inside the drive.

A discrete termination network of 124 Ω at 1% tolerance, rated 200 mW, can be clipped to the bus to suppress reflections on long cable runs. The En2 card’s supply ladder delivers 350 mA, enough to bias absolute encoders with multi-turn memory while staying within the 6 W envelope. Field wiring is secured by clamp screws that must be tightened to 0.5 Nm, and this setting protects the PCB pads without risking thread damage. Integrated Safe Motion functions stop or limit movement through hardware channels, and those functions only arm when an encoder is present.
