Product Description:

The CSH01.1C-PL-EN2-NNN-MEM-NN-S-NN-FW motion-logic controller belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. It mounts inside Rexroth drive racks and serves as the coordination layer between servo power stages, feedback devices, and supervisory PLC networks. Within an automated cell, it converts position and speed setpoints into time-critical electrical commands while collecting sensor data for closed-loop regulation. By combining analog conversion, pulse train generation, and dedicated encoder evaluation on one board, the unit streamlines axis control in packaging, printing, and material-handling machinery.

The controller operates from a regulated 24 V DC supply and draws only 7.5 W at its backplane, which helps minimize cabinet heat. For process monitoring, it offers two differential analog inputs with a high 160 kOhm impedance that protects upstream signal conditioners and accepts a full-scale range of ±10 V. A fixed 5 V analog output is available for reference tasks. Conversion on the EN2 channel is handled by a 12-bit ADC, enabling precise reconstruction of incremental encoder waveforms before software filtering. Single-shot events, such as latch or probe signals, are accepted with pulse widths as short as 100 ms, and discrete exchange with external devices is routed through a D-Sub 37-pin parallel connector.

Additional feedback flexibility is provided by a shielded EN2 line that supports 75 m cable runs with sense conductors and delivers a stabilized 5.0 V DC source rated at 350 mA. The MEM interface, presented on a D-Sub 15-pin socket, drives differential outputs up to 1 MHz across 40 m cables for high-speed position latching. Sixteen programmable inputs and sixteen outputs, shown as 16 In / 16 Out, let the card react to sensors without additional I/O cards. During power-up, the unit may draw an inrush of 4 A, a figure used when sizing feeders and protection fuses.
