Product Description:

The CSH01.1C-SE-EN1-NNN-NNN-NN-S-NN-FW is a motion-control master built by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It operates as a central axis processor that links drives, operator stations, and higher-level PLCs, providing deterministic command exchange in automated cells and machine tools. Its control role allows coordinated motion data to pass between the control system and connected axes. By concentrating axis coordination in one controller, it helps keep motion sequencing, command distribution, and status handling aligned across interconnected machine sections. The controller is intended for automation tasks that require predictable timing between command updates and drive response.

Command traffic to the drives is handled on the SERCOS II bus, and the optical ring relies on Fiber Optic Cables to maintain noise-immune transmission at high baud rates. For parameterization or service access, the module exposes a RS232 port. The two analog input channels present an impedance of 160 kΩ, which helps prevent loading of upstream sensors, while the encoder supply delivers a regulated 8 V reference for resolver feedback. Digital inputs accept 24 V logic and draw 3 mA each, and eight sourcing outputs switch the field supply for external devices. A single-line control-panel display shows status without opening the cabinet. The unit has no integrated safety functions, so external safety relays must handle emergency-stop chains.

Analog command signals are sent through an output stage that sources 1 mA, and the voltage output is rated at 5 V for position command signals to legacy drives. Discrete actuators such as contactors or solenoids can be powered directly from the transistor outputs up to 0.5 A, and heavier loads are routed through an onboard relay contact rated at 1 A. Resolver and HSF feedback signals are decoded by the Resolver And HSF evaluation option, which lets the controller interpolate high-resolution position data from MHD and MKD motor encoders. The outputs mirror the field supply, so a clean external supply is needed for stable switching. The relay contact can be used when a device needs an isolated switching path instead of a direct transistor output.
