Product Description:

The CSH01.1C-SE-ENS-EN2-NNN-NN-S-XP-FW is a motion and I/O controller manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted in a drive rack, it translates fieldbus commands into position, velocity, and torque references for connected servo inverters. Within an automated line, the unit links feedback devices to the higher-level PLC, delivering deterministic axis coordination and permitting synchronized multi-axis operation in assembly, packaging, and material-handling cells. Its integrated control and interface functions also allow command handling and feedback processing to remain within a single rack module.

Communication runs on SERCOS II, with a maximum ring speed of 16 MBaud that keeps setpoint latency low. Analog inputs present 160 kΩ of impedance, so they do not place a heavy load on strain gauges or temperature transmitters. Each analog output changes in steps of 19.5 mV/inc, which allows smooth reference signals for external drives. Time-critical events are latched with a probe accuracy of 1 µs. Encoder channel 1 uses a D-Sub 15 female connector powered at 12 V, while encoder channel 2 is powered at 5 V and supports shielded feedback cable runs up to 75 m with sense conductors that correct for voltage drop. Two onboard relays can switch 24 V DC at 1 A for motor brake release or safety interlocks.

At startup, the controller draws an inrush of 4 A for 100 ms, then stabilizes at only 21.5 W of continuous demand, which helps simplify cabinet thermal planning. Each digital driver point can deliver up to 500 mA, so small status devices or similar field loads can be driven directly from the module. For setup or service, an RS-232 port runs at up to 115 kBaud over cables limited to 15 m, providing parameter access when the optical ring is disconnected. This local serial connection also provides a direct path to diagnostics when the fiber-optic network is unavailable.
