Product Description:

The CSH02.1B-CC-EC-ET-NN-EC-NN-FW is a motion and logic controller manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. This unit coordinates servo drives and peripheral devices over real-time Ethernet networks, acting as the central axis controller inside modular machinery such as packaging lines, pick-and-place cells, and printing stations. By combining deterministic communication and multi-encoder evaluation in one housing, the controller simplifies cabinet wiring while delivering synchronized axis control for typical industrial automation cycle-time demands.

In analog tasks, the board provides a voltage path with a resolution of 14-bit, translating to discrete steps of 24 mV per increment so small command changes can be reproduced at the drive with minimal quantization error. The control electronics are powered from DC 24 V and draw a base load of only 17 W, which helps limit demand on the control cabinet supply. Inside the controller, the sinusoidal commutation channel is filtered at 400 kHz, while the square-wave channel is allowed up to 1000 kHz. These bandwidth limits support accurate processing of high-resolution encoder signals through the two multi-encoder interfaces.

At startup, the supply may momentarily surge to a maximum of less than 5 A, which is useful when sizing protective devices and backup power capacity. Command pulses to downstream inverters are limited to 1 ms, which helps avoid excess gate stress during rapid axis reversals. On the network side, the Multi-Ethernet option recognizes Sercos III, EtherCAT, EtherNet/IP, and PROFINET IO, allowing the controller to join different machine networks while operating as a Sercos III master. Safety technology is not included, so external safety relays are required, and the controller is intended for use with HCS02, HCS03, HCS04, HMS01, and HMS02 power sections.
