Product Description:

Bosch Rexroth Indramat's CSH01.1C-NN-ENS-MEM-MA1-NN-S-XP-FW control section belongs to the CSH Advanced Controllers series and slides into an IndraDrive power stage to form a compact controller-drive assembly. It functions as the central processor for axis coordination, data acquisition, and real-time command generation in industrial automation cells such as packaging, printing, and material handling lines. By integrating multiple option cards on a single board, it reduces cabinet wiring and shortens signal latency between motion tasks. This arrangement keeps control, feedback processing, and local I/O handling inside the drive enclosure instead of distributing them across separate modules.

The board offers 11 digital inputs that accept 24 V sourcing signals and 4 digital outputs for low-current switching of interlocks or lamps. Core electronics draw a base power of 7.5 W, and a momentary inrush current of 4 A occurs when 24 V DC is first applied. The ENS encoder option is supplied with 11.6 V DC, samples quadrature channels through a 12-bit converter, and tracks edge transitions up to 500 kHz so high-resolution feedback is preserved at speed. Two MA1 analog inputs and two analog outputs handle ±10 V process variables, and the MA1 circuitry consumes 2 W. These analog channels allow the control section to exchange reference and monitoring signals with external process equipment.

The MEM pulse generator issues step trains at frequencies as high as 1 MHz for synchronized control of secondary axes, while accepting command durations down to 100 ms for one-shot positioning. Its logic dissipates 2 W, and the combined ENS block adds 6 W, which should be included in the auxiliary 24 V supply load. A built-in RS-232 service port supports diagnostics and serial communication at up to 115 kBaud. This port is useful for local access without occupying the main motion network. The available digital, analog, encoder, and pulse interfaces support mixed-device integration within the same drive assembly.
