Product Description:
The CSH02.1B-CC-EC-ET-L3-EC-NN-FW is an automation controller from Bosch Rexroth Indramat that belongs to the CSH Advanced Controllers series. Inside a drive cabinet, it manages signal conditioning for encoders, analog references, and safety relays so individual axes receive precise position and status information. By supplying regulated sensor power and decoding high-resolution inputs, the unit serves as the coordination layer between motion hardware and a higher-level PLC in industrial production cells. It is intended for drive systems that need reliable feedback handling and stable command exchange across multiple connected interfaces.
The controller’s base electronics draw 17 W, which adds to the thermal load that must be removed from the panel. For fast current-loop processing, it accepts feedback with a bandwidth of 1.3 kHz, keeping control delays short in dynamic servo applications. Its X32 port digitizes voltage feedback at 14 bit resolution, allowing fine scaling when monitoring field transducers. Mechanical outputs such as brakes or contactors can be driven through an internal relay rated to carry 1000 mA, while the differential analog channel sets reference levels in steps of 24 mV/incr so the drive can follow smooth speed ramps without noticeable quantization steps.
Additional resources complete the interface set. The 5 V encoder supply delivers up to 500 mA, and a resolver carrier at 8 kHz supports sensors that rely on sinusoidal excitation. When encoders with integral heaters or LEDs are used, their consumption must remain below 6 W to stay within the permitted load budget. Safety chains that interrupt motive power can switch through the relay as long as the line voltage does not exceed 30 V. Option cards draw fixed increments of 1.1 W for each EC module, 2.7 W for the ET network link, and 1.0 W for the L3 interface, so the total supply demand and cabinet cooling can be estimated with predictable margins. This arrangement helps the controller support a mixed interface set without requiring separate external signal-conditioning hardware for each connected device.
