Product Description:

The CSH01.1C-NN-EN2-NNN-MD2-S2-S-NN-FW is a single-axis control unit produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It operates as the logic layer in an automation cell, processing encoder feedback and field inputs to manage motion tasks while the power section supplies current to the motor. By issuing position, velocity, and safety commands, the module allows actuators to follow programmed sequences with reduced dependence on an external PLC. It is intended for applications where fast processing of motion feedback and machine signals is needed at the axis level.

Base power consumption is 7.5 W, so the controller places only a small continuous load on the cabinet supply during normal operation. A typical inrush of 4 A must still be considered when sizing fuses and startup relays. The embedded RS-232 port exchanges diagnostic data at up to 115 kBaud over cables no longer than 15 m, providing a direct service connection for parameter access. Motion feedback arrives through the EnDat 2.1 interface, and its analog sine signals are filtered at 500 kHz to reduce aliasing before digital conversion. This supports stable communication and reliable encoder signal handling during routine operation.

The expansion connector supports 16 digital inputs and 16 digital outputs, allowing direct wiring of sensors and solenoid valves without separate interface hardware. This arrangement lets the controller exchange local status and switching signals without adding another interface module. Square-wave encoder edges are accepted up to 1000 kHz, a rate suited to fast feedback processing on short-stroke axes. The encoder supply delivers 350 mA at 5.0 V, enough to power resolvers or multi-turn sensor heads through cables up to 50 m without sense lines, or 75 m when sense conductors compensate for voltage drop. A relay channel rated for 1 A at 30 V DC provides an isolated fault contact that can be tied into external interlock circuits.
