Product Description:

The CSH01.1C-NN-ENS-NNN-MEM-S1-S-NN-FW is a plug-in motion and safety controller produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It attaches to IndraDrive power sections and supervises servo loops, digital inputs, encoder decoding, and integrated safety logic. In automated packaging lines, material-handling cells, and CNC equipment, the board converts fieldbus commands into synchronized position, velocity, and torque references for each connected axis while occupying a single control slot in the drive rack.

The module draws a base power of 7.5 W, so thermal loading inside a closed cabinet remains low. All electronics are fed from a backplane rail at DC 24 V, and a soft-start circuit limits current during engagement. Discrete command lines are interpreted by the controller; any terminal under 5 V is treated as logic low, whereas levels above 15 V are treated as logic high. The encoder interface supplies 11.6 V to external sensors and receives incremental or absolute tracks through a D-Sub 15 female connector. These signals pass through differential receivers that are galvanically isolated from the drive power stage to prevent ground loops. A form C relay rated for DC 24 V / 1 A is available for ready, fault, or brake-release signaling.

For safety circuits, the board uses a D-Sub 9 female connector, and its inputs draw 24 V at 3 mA while its semiconductor outputs can source 24 V at 0.5 A. An input termination impedance of 120 Ohm preserves encoder signal integrity, and the TTL counter accepts edges up to 400 kHz for high-speed length or speed measurement tasks. During power-up, the capacitors charge with an inrush of 4 A, and watchdog logic disables motion if command gaps exceed 100 ms. The relay contact and isolated feedback routing support predictable response times and safe shutdown paths in multi-axis machinery.
