Product Description:

The CSH01.2C-SE-EN2-EN1-CCD-S1-S-NN-FW is a single-axis control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Designed for high-performance industrial automation, the module installs in an IndraDrive power unit and coordinates motion sequences, safety inputs, and real-time field communication for demanding axis applications. It links drive hardware to supervisory PLCs, collecting encoder data and transmitting deterministic commands so that multi-axis machinery maintains precise position, velocity, and torque profiles during production across packaging, printing, and assembly lines.

Only 8.5 W of base power keeps the logic, memory, and diagnostic circuits active, minimizing standby energy use and cabinet cooling demand. Axis updates move across the optical ring, and the controller uses the SERCOS protocol at 62.5 µs cycles to synchronize drives. The first encoder interface supports resolver carriers at 4 kHz, allowing high angle resolution without saturating the analog front end. That channel supplies 18.2 Vpp excitation so passive resolvers return a clean position signal. Protective routines can issue a single-shot pulse up to 100 ms long to limit brake release during a detected fault. Additional interfaces include EnDat 2.1, 1 Vpp sin/cos, 5 V TTL feedback, a 100Base-TX engineering port, and a Mini-DIN RS-232 console for cables up to 15 m.

The second encoder supply provides 350 mA at 5.0 V DC, giving adequate current for multiturn EnDat or HSF transducers while preventing overload on the logic rail. During power-up, the control section can draw an inrush of 4 A, so line fuses and breakers must accommodate that short-duration surge. For integrated safety, the module sources programmable outputs rated at 24 V / 0.5 A, enabling direct connection to relays or contactors that remove motive power when an emergency stop is triggered. Power, feedback, and safety functions remain integrated within the same compact control section.
