Product Description:

The Bosch Rexroth Indramat CSH01.1C-CO-EN2-NNN-MD1-S2-S-NN-FW is a single-axis motion logic controller from the CSH Advanced Controllers series. It coordinates servo drives and feedback devices within modular machinery, providing real-time command processing, fieldbus communication, and encoder evaluation for precise axis positioning in industrial automation. By integrating communication interfaces and safety outputs, the module functions as the central processor inside Rexroth drive packages, directing velocity, torque, and safe stop functions on connected power stages.

At the board level, the controller draws a base power of 7.5 W, allowing low-heat installation in compact cabinets, and it can tolerate a momentary startup surge of 4 A without nuisance trips. The analog front end presents 160 kΩ of input resistance, so external sensors place negligible load, and each analog output is quantized at 19.5 mV/inc for fine setpoint generation. Twelve MD1 digital inputs accept 24 V signals for command or limit detection, while eight transistor outputs return status to higher-level PLCs. The EN2 option port supports EnDat 2.1, 1 Vpp, and 5 V TTL encoders so the controller can read absolute or incremental feedback without extra gateways.

For networked motion, the unit supports DeviceNet and CANopen. On a CANopen line, it maintains data integrity over 100 m at 500 kbaud and organizes up to 127 nodes, whereas a DeviceNet segment can include 64 addressed devices. When point-to-point diagnostics are needed, the integrated RS-232 port streams parameters at 115 kBaud. Two relay contacts are rated 24 VDC / 1 A for enabling external brakes or contactors, and the Safe Motion terminal supplies 24 V at 0.5 A to trigger certified shutdown circuits. For encoder wiring, the EN2 connection supports up to 75 m when sense leads are used and 50 m without them, allowing flexible cabinet placement.
