Product Description:

The CSH01.1C-SE-ENS-ENS-NNN-S1-S-NN-FW is a single-axis command card from Bosch Rexroth Indramat in the CSH Advanced Controllers series. Installed in an IndraDrive modular rack, the card translates drive parameters, feedback data, and machine commands so that servo axes follow programmed motion profiles. Its role in industrial automation is to provide deterministic control loops and to interface the power section with supervisory PLC or HMI layers for precise positioning, speed regulation, and diagnostic reporting in packaging, printing, and material-handling equipment.

On the analog side, the controller accepts feedback through an input path that presents 180 kΩ of resistance, reducing loading on external sensors, while its voltage output circuit updates in steps of 19.5 mV per increment for fine actuator reference generation. Internal electronics draw only 7.5 W of base power, which is relevant when planning cabinet power distribution and heat dissipation. Motion and parameter data are exchanged over the SERCOS II fiber-optic bus, giving synchronous communication to the drive stack. Four digital high-side drivers can source up to 500 mA each for brakes or status lamps, and the board carries two ENS encoder interfaces for dual-loop position feedback.

Each ENS port offers an input impedance of 120 Ω and is energized by an isolated supply of 11.6 V, supporting clean differential signaling across long motor cables. Capture circuits tolerate command pulses as wide as 100 ms, and a TTL counter tracks position streams up to 400 kHz for high-speed rotary encoders. The S1 service connector is a D-Sub 9 female socket, and its opto-isolated inputs draw 3 mA while its outputs can sink 0.5 A or switch a relay rated at DC 24 V / 1 A. When the card powers up, a typical inrush of 4 A must be supported by the control supply fuse.
