Product Description:

The CSH01.2C-PB-ENS-ENS-CCD-NN-S-NN-FW module belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. It serves as the control section within IndraDrive power units, executing motion commands and coordinating fieldbus data for multi-axis machinery. Through the integrated PROFIBUS-DP master interface and SERCOS III cross-communication link, the board exchanges set points, status words, and diagnostics with higher-level PLCs and neighboring drives to maintain synchronized operation across an automated line.

The analog domain is designed for precise scaling: the differential input has a resistance of 160 kΩ, minimizing load on upstream sensors, while each voltage output can source up to 1 mA. Output steps are quantized at 19.5 mV/inc, so small command changes translate into fine-grained motor torque adjustments, and the full-scale reference is 5 V. Internal electronics require only 8.5 W of base power, which helps limit cabinet heat buildup in densely packed drive stacks. Two standard encoder evaluation channels accept TTL or RS-422 feedback, and the board delivers 11.6 V at 500 mA for their supply. Relay logic is available on a 24 V DC, 1 A contact for external interlocks such as brake release valves.

During startup, the power rail briefly demands 4 A for 100 ms, so line protection devices must tolerate that inrush without nuisance tripping. Position capture accuracy is maintained because the probe circuitry guarantees a timing error within 1 µs when registering the rising edge of an external marker, and the generated strobe pulse remains valid for 4 µs to match common opto-sensor requirements. Cyclic telegrams ride on PROFIBUS at up to 12 MBaud, allowing rapid parameter refresh even when several axes share the same segment. This supports deterministic motion profiles in presses, packaging equipment, and material-handling gantries.
