Product Description:
The CSH02.1B-CC-EC-NN-L3-NN-NN-FW is a motion-logic controller from Bosch Rexroth Indramat in the CSH Advanced Controllers series. Designed for multi-axis drive packages, it coordinates servo loops, gathers encoder feedback, and exchanges real-time data with higher-level PLCs. By combining encoder management, fieldbus processing, and relay handling in a compact module, the unit provides deterministic control for packaging lines, material handling systems, and machining centers where synchronized axis timing is required.
The module communicates with drives over the SERCOS III master interface for cyclic setpoint and feedback exchange. Each analog output refreshes in 750 µs, which helps limit latency for speed or torque references. The analog outputs provide a step size of 24 mV per increment into loads down to 2 kΩ, so connected devices receive fine voltage changes without overloading the converter. Measurement resolution on X32 is fixed at 14-bit, yielding 16,384 levels. The X35 current input has an input resistance of 300 Ω to help reduce distortion. A multi-encoder interface can source 500 mA at 5 V, and a separate 12 V rail supports sensors that require a higher supply voltage.
The control section draws only 17 W during normal operation, yet it can drive field devices through standard outputs rated at 500 mA and relays that switch up to 1000 mA. A resolver carrier of 8 kHz supports rapid angle tracking for position loops. The safety circuit provides the Safe Torque Off function through a dedicated channel that can source 350 mA for downstream logic. Protection against inrush is handled by a pulse limiter capped at 1 ms, which reduces stress on supply components during cabinet power-up. This arrangement also supports brake control and safety shutdown signaling without external signal-conditioning hardware.
