Product Description:

The CSH01.1C-ET-EN2-MA1-MD1-L2-S-XP-FW belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. Installed as the control section in modular drive platforms, it coordinates motion tasks, safety functions, and real-time network traffic for multi-axis machinery. Within an automation cabinet, the controller interprets fieldbus commands, supervises encoder feedback, and issues gate signals so that connected power stages run the motor according to the higher-level program.

The unit provides a differential analog input, and an MA1 expansion uses the same ±10 V span for speed or torque references. A transistor digital output is rated at 24 V / 0.5 A for status forwarding, while the internal logic and network circuits draw only 7.5 W, which helps keep panel heat low. Network access is supplied through Multi-Ethernet, and the port supports 100Base-TX signaling. Feedback processing is handled by an EnDat 2.1 interface that also accepts 1 Vpp and 5 V TTL formats, while a dedicated 5 V line powers the attached encoder. Power-up demand is limited by an inrush current of 4 A, and timing outputs can generate pulses up to 100 ms for direct trigger control of auxiliary devices.

The optional MA1 card adds 2 analog inputs and 2 analog outputs, each sampled at a resolution of 12 bits, which is suitable for moderate-precision tension or pressure loops. Discrete automation requirements are met by the MD1 module, which supplies 12 inputs and 8 outputs on 24 V logic. Safety stop channels connect through an STO input that senses 24 V at 3 mA, while relay contacts carry up to 24 V DC at 1 A for redundant isolation. When cabling is routed across a plant floor, the Ethernet interface maintains deterministic traffic over distances up to 100 m without repeaters, provided Category 5e or better cable is installed.
