Product Description:

The CSH01.1C-S3-ENS-NNN-MD1-S1-S-NN-FW is a motion logic controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It mounts into IndraDrive power sections to manage axis control, feedback processing, and functional safety in automated machinery. By combining high-speed encoder evaluation with drive-integrated PLC tasks, this unit coordinates position, velocity, and diagnostic data across multiple servo axes inside a single automation cabinet. Because the control functions are integrated into the drive platform, the system can process motion feedback locally without requiring a separate external motion controller for every axis.

The housing is compact; its width is 49.5 mm, its depth is 103 mm, and its height is 241 mm, allowing dense installation in drive cabinets. An internal converter digitizes sine-cosine feedback with an effective 12-bit resolution per revolution, and the input stage accepts incremental or absolute encoders up to 500 kHz carrier frequency. Twelve digital inputs and eight digital outputs are routed through the MD1 module, while a D-Sub 25 connector simplifies field wiring. A maximum pulse width of 100 ms can be generated for time-critical output strobes, the encoder supply can source 500 mA for transducer power, and the dedicated safety I/O channel carries 1.6 A with overcurrent monitoring.

Motion data is exchanged over SERCOS III, and the port operates at 10/100 Base-T for standard Ethernet-based network integration. The network interface can be connected to common industrial Ethernet infrastructure without separate media conversion. The inrush limiter restricts startup draw to 4 A, helping keep cabinet fusing within common ratings. Safety circuits and logic boards share a stabilized 24 VDC supply, enabling stop functions and controller logic to remain available when the main power stage is removed.
