Product Description:

The CSH01.2C-SE-EN2-NNN-CCD-NN-S-NN-FW is a motion-control module from Bosch Rexroth Indramat in the CSH Advanced Controllers series. Installed in a drive cabinet, it supervises servo axes, gathers field signals, and exchanges deterministic data with master PLCs through SERCOS communication. It is intended for high-speed positioning and process functions in automated assembly lines, packaging machines, and material-handling cells where tight synchronization and fast signal handling are important. In these applications, the controller links motion commands, feedback evaluation, and probe processing so multiple machine sections can react in a coordinated way during continuous operation.

The controller conditions two differential analog inputs that accept a span of ±10 V, and a high input resistance of 160 kΩ helps reduce loading on connected transducers. Two voltage outputs deliver setpoint signals across a 0 to +5 V range and may be connected to drives or regulators with a load of at least 5 kΩ. Each output step is quantized in 19.5 mV/inc increments, which supports fine adjustment in torque or process-control loops. Probe events are time-stamped with 1 microsecond accuracy, and captured positions can be forwarded over the SERCOS II control channel or the SERCOS III cross-communication bus. Encoder inputs for EnDat 2.1, 1 Vpp, and 5 V TTL devices allow the module to work with a wide range of rotary and linear feedback units, while the 100Base-TX engineering port supports setup and service access.

Digital I/O is powered from a 19 to 30 V DC rail, and each input expects 24 V / 3 mA signals. Every logic output can source up to 24 V / 0.5 A for relays or indicator lamps, allowing the controller to exchange status and command signals with surrounding machine hardware. Internal electronics draw a base load of 8.5 W, while a typical inrush of 4 A lasts no longer than 100 ms. This helps explain the temporary demand that appears at power-up without affecting normal running consumption. Start-up sequencing, watchdog handling, and diagnostics are carried through the same SERCOS telegrams used for real-time setpoints, which keeps control behavior consistent across multi-axis drive platforms.
