Product Description:
The CSH01.2C-SE-EN2-MA1-CCD-S1-S-NN-FW is a drive and motion controller module manufactured by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It serves as the central axis processor inside modular Rexroth drive stacks, executing position, velocity, and safety functions for servo motors while handling I/O coordination between the drive and higher-level PLCs. By using SERCOS fieldbus messaging, the unit links directly to automation networks and provides the deterministic telegram timing required for multi-axis synchronization in industrial automation lines.
The controller draws a base load of 8.5 W, which simplifies cabinet heat calculations and allows passive convection in many enclosures. Command and feedback data move across a SERCOS optical ring that supports cyclic setpoint exchange with minimal jitter. For encoder power, the logic board supplies 5.0 V, a regulated rail matched to EnDat 2.1, 1 Vpp, or 5 V TTL sensors used in the encoder signal group. Two differential analog inputs and two analog outputs are provided on the MA1 daughter card, and their conversion depth is 12-bit, giving 4096 discrete steps for process values. When sense leads are used, feedback cables may span up to 75 m without degrading excitation tolerance, which supports large machine footprints while maintaining precise position references.
The encoder line can deliver up to 350 mA, which is sufficient for most multi-turn absolute encoders with integrated diagnostics. Safety terminals accept logic at 24 V / 3 mA and can switch actuator loads up to 24 V / 0.5 A through the D-Sub 9 female connector, allowing safe torque-off circuits without external relays. Service computers attach through the 100Base-TX engineering port, enabling parameter uploads over standard Ethernet cabling. Cross communication functions let the module operate as a SERCOS III master, while motor leads can reach 50 m when sense wiring is omitted. A single-line display on the standard control panel provides local status for quick diagnostics.
