Product Description:

The CSH01.1C-ET-ENS-EN1-MEM-S2-S-NN-FW is a motion and communication controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. The module occupies the command layer of a Rexroth drive stack, converting PLC setpoints into synchronized current, velocity, and position commands for connected power sections. Integrated Safe Motion functions allow it to monitor axis states and trigger controlled stops, so the unit fits packaging, printing, and material-handling machines that demand coordinated and safety-rated drive control. Because command processing is handled centrally, the controller can keep multiple axes aligned during interpolation, speed changes, and load disturbances.

The module’s analog interface presents an input resistance of 160 kOhm, so voltage-type process signals can be sampled without significant source current. Its analog output is rated at 5 V, 1 mA, making it suitable for low-power reference tasks in circuits that expect a stabilized drive signal. Closed-loop torque regulation runs on a current control cycle of 125 µs, giving the drive bandwidth for high-dynamic servo tasks. Communication to upper-level controls occurs through a dual-port Ethernet switch that follows the 100Base-TX standard, which supports straightforward inline network routing between adjacent devices. For test stands or master-encoder replication, an emulation channel can drive incremental receivers over cables up to 40 m long without timing loss.

The same emulation output can pulse at up to 1 MHz, allowing the controller to mirror high-resolution encoder streams for auxiliary axes. The safety encoder channel draws only 250 mA from its 8 VDC source, leaving current headroom for several feedback devices on the shared rail. Logic groups powered by the ENS connection require a stabilized input of 11.6 VDC, which helps separate control electronics from the main drive bus. For discrete diagnostics or interlocks, an onboard relay supplies dry contacts that can switch loads up to 24 VDC, 1 A without external amplification. This relay output can be used for status signaling to machine-level control circuits that require a simple isolated contact.
