Product Description:

The CSH01.1C-SE-NNN-NNN-NNN-L2-S-XP-FW is a motion-logic controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It coordinates servo drives and peripheral devices by processing axis commands, feedback, and machine sequencing inside a modular automation rack. The unit is used in industrial automation to execute deterministic control cycles, exchange data with higher-level PLCs, and supervise drive safety functions so multi-axis machines can position, synchronize, and stop with minimal cycle time.

The controller provides one differential analog input that accepts ±10 V signals for speed or torque references, while two analog outputs rated at 2 × 5 V provide scaled setpoints to external modules. A separate analog channel can sink up to 1 mA, permitting simple meter or transmitter feedback. Internal electronics draw only 7.5 W of base power, so heat generation remains low in compact cabinets. Four user-assignable terminals offer 4 points of configurable I/O. Each point can be parameterized for fast edge capture or status reporting, which allows flexible mapping of sensors and actuators without extra interface cards.

The digital section is energized from a field supply of DC 19 to 30 V, which supports seven opto-isolated inputs for limit switches, probes, and interlocks. During startup, the power stage draws an inrush of 4 A, so wiring must tolerate that brief load before steady-state current settles to 1.1 A. Integrated drive interlock circuitry provides Safe Torque Off (SIL3, Cat.3 PL e), enabling emergency stops without additional relays. Real-time motion commands are exchanged over the SERCOS II master interface, while a separate RS-232 port supports service diagnostics and local parameter access without interrupting the deterministic control bus.
