Product Description:

The CSH02.1B-CC-EC-ET-L3-EM-NN-FW is an advanced motion and logic controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. The unit serves as the central processor in multi-axis automation cells, coordinating servo drives, field devices, and human-machine interfaces through its modular communication layers. It can manage synchronized motion, device communication, and local control tasks from a single platform. The hardware platform includes 3 optional slots, so the base unit can accept encoder emulation, extra fieldbuses, or specialty I/O cards without replacing the controller.

At the I/O level, the controller provides 2 analog outputs for continuous voltage or current references and 11 digital inputs that accept 24 V status signals from sensors and limit switches. Each digital output channel can source up to 500 mA, allowing it to drive contactors or pilot lamps without external relays. Motion loops are refreshed on a 250 µs position control cycle, so high-speed axes can be interpolated without noticeable lag. Despite this update rate, the motherboard draws only 17 W of base power, helping reduce cabinet power demand. Add-on cards are also low in power consumption, which helps simplify thermal management in compact enclosures. This supports installations where low heat output and stable control response are both important.

Network coordination is handled by the built-in SERCOS III master, which distributes real-time setpoints and feedback frames to drives over fiber-optic or copper rings. Functional safety includes the STO shutdown channel, which removes drive torque when a guard opens or an emergency stop is pressed. Configuration and diagnostics use an RJ-45, 8-pin engineering port that operates at 100Base-TX Ethernet speed for fast data exchange and oscilloscope tracing.
