Product Description:

The CSH02.1B-CC-EC-EC-SB-NN-NN-FW is a motion-logic controller from Bosch Rexroth Indramat that belongs to the CSH Advanced Controllers series. It is intended to coordinate multiple servo drives, field devices, and safety modules in automated lines, providing the central processing and timing that link machine sequence control with real-time axis regulation. Position, velocity, and current processing remain deterministic across machine layouts because the controller handles both sequencing and motion tasks in one platform, which helps coordinated axes react consistently to command changes and machine events.

Control exchange occurs through a SERCOS III master network interface that delivers deterministic Ethernet telegrams to each drive. The internal current loop closes every 62.5 µs, the velocity loop every 125 µs, and the position loop every 250 µs, which supports smooth torque commands, stable speed regulation, and fast settling on high-bandwidth mechanisms. Integrated safety is implemented with the Safe Motion Bus, enabling safe stop, limited speed, and related motion-protection functions without external relays or separate hardwired safety chains. Five configurable digital I/O lines can be mapped as interlocks or status outputs, and the engineering interface uses an RJ-45 8-pin port for setup or service access. A maximum pulse width of 1 ms is available for pulse-train style outputs, while each EC module draws only 1.1 W and the SB safety module adds 2.5 W to the thermal budget.

For conventional signaling, the controller supplies 2 analog outputs with a ±10 V range for drive setpoints and 11 dedicated digital inputs for limit switches, probes, or fast capture tasks. The available inputs and outputs let the unit handle reference signals and discrete machine states without requiring a separate interface card. The unit’s continuous power draw is 17 W, and cabinet protection is simplified because the inrush current stays below 5 A. Overall consumption remains low even when optional modules are installed, which helps keep cabinet thermal load and UPS demand low in compact control cabinets or multi-axis systems.
