Product Description:

The CSH02.1B-CC-EC-PB-S5-NN-NN-FW is a compact motion and logic controller manufactured by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. Installed in drive cabinets, it supervises servo axes, processes sensor feedback, and distributes fieldbus messages so that automated equipment follows precise position and velocity profiles. The device combines centralized CPU resources with dedicated encoder electronics, allowing coordinated motion, camming, and interpolation without adding separate PLC cards. Its low power demand and integrated safety functions make it suitable for compact cells where panel space is limited and cabinet layouts must remain organized.

At its core, the unit uses a 12-bit successive-approximation A/D converter to digitize analog feedback. Three analog inputs accept ±10 V process signals, and two analog outputs drive external regulators for connected motion devices. Servo drives exchange setpoints through the SERCOS III master channel, while 11 digital inputs monitor limit switches and interlocks. A Multi-Encoder Interface routes position data and delivers 500 mA at 12 V to the transducers. An RJ-45 eight-pin engineering port permits parameterization, and a D-Sub fifteen-pin female socket handles motor-encoder wiring. Continuous operation requires only 17 W, which helps reduce heat buildup inside the control cabinet during normal use.

For plant-level communication, the controller adds a PROFIBUS stack accessed through a D-Sub nine-pin female connector near the probe terminals. Two probe inputs capture registration marks with hardware time-stamping, which supports repeatable synchronization during fast machine cycles. The square-wave counter accepts encoder signals up to 1000 kHz for high-speed scales, allowing responsive position capture from external measuring devices. Integrated safety is provided by the Safe Motion package, enabling certified stop and monitoring functions without extra relays. This arrangement supports multi-axis coordination while keeping signal handling and network communication inside one compact control platform.
