Product Description:
The CSH01.1C-S3-ENS-MEM-MA1-S2-S-NN-FW belongs to the CSH Advanced Controllers series produced by Bosch Rexroth Indramat. As a compact motion-logic controller, it coordinates servo drives and peripheral I/O so that multi-axis machines follow programmed paths and safety sequences without an external PLC. The unit integrates communication, encoder handling, analog conversion, and safe-motion supervision into a single slot card that fits Rexroth drive racks used in packaging, printing, and material-processing lines. This arrangement keeps control functions close to the drive system and reduces the need for separate cabinet hardware for axis coordination.
An Ethernet service interface is provided through a RJ-45, 8-pin connector, allowing parameter access and diagnostic communication. For real-time axis coordination, the controller links to the drive bus over SERCOS III, which carries cyclic setpoints and process data with deterministic latency. The MA1 option board offers two differential analog inputs and two outputs, each working across a ±10 V span so external sensors and actuators can be read or driven without additional converters. Encoder supply resources include a continuous current of 500 mA at a regulated level of 11.6 V, which supports absolute or incremental feedback devices while helping maintain stable operation on short cable runs. Standard encoder evaluation logic decodes position and velocity data for closed-loop control. Because the analog channels are integrated into the option board, nearby process signals can be connected directly to the controller.
Motion commands generated in the MEM channel are clocked out at 1 MHz, and the associated encoder-emulation cable may be extended up to 40 m before signal integrity limits are reached. Functional safety inputs arrive on a D-Sub 9-pin connector where each channel is validated against a threshold of 24 V / 3 mA. The integrated SafeMotion package enables Safe Motion functions such as safely limited speed and safe stop, so axes can be brought to a protective state without removing power from the entire drive system. This supports localized safety response while keeping the control structure tied to the drive platform.
