Product Description:

The CSH01.1C-S3-EN2-NNN-MD2-NN-S-NN-FW is a motion and I/O controller produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It serves as the central command unit in a modular drive stack. It generates setpoints, evaluates encoder feedback, and coordinates axis timing so that packaging, handling, and assembly stations maintain precise speed and position relationships.

An analog input range of ±10 V accepts differential speed or torque references, and the corresponding input impedance of 160 kΩ places only a minimal load on source hardware. A separate channel supplies a control signal from 0 to +5 V, allowing status values to be forwarded to recorders or indicators. High-speed deterministic exchange with machine PLCs is carried over SERCOS III, providing cycle-synchronous data across fiber or copper rings. Field sensors and actuators draw power from the integrated supply rated at DC 19 to 30 V, eliminating the need for an external 24 V source. When an EnDat 2.1 encoder is connected, the EN2 receiver maintains signal fidelity by limiting line loading to 35 Ω, which helps preserve clean square waves for accurate interpolation.

Encoder electronics are powered by a regulated output of 5.0 VDC at up to 350 mA, supporting multiturn absolute transducers with internal diagnostics. The optional MD2 slice adds discrete control through 16 In / 16 Out digital channels that are divided into four galvanically isolated groups and can switch 0.5 A at 24 V for contactors or lamps. For setup and service, a built-in RS-232 interface offers data throughput to 115 kBaud over cables as long as 15 m, allowing local parameter access without using the real-time network. When the Digital I/O with SSI option is installed, the controller can also process absolute position data over SSI and forward 1 Vpp or 5 V TTL encoder signals to downstream drives.
