Product Description:
The CSH01.1C-NN-ENS-EN2-MD2-S2-S-NN-FW is a single-axis motion controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It coordinates servo drives and feedback devices in automated assembly cells, packaging equipment, and other factory processes, providing deterministic axis guidance for industrial automation. This arrangement allows the controller to manage motion commands and feedback evaluation in applications that need predictable axis behavior during repeated machine cycles. Because the control-bus option slot is left empty, the controller has no control communication module installed, so integration relies on drive-based fieldbus links or the RS-232 service port.
The controller presents two differential analog inputs with an input resistance of 160 kΩ, so connected sensors experience minimal loading. Each channel resolves changes down to 1.23 mV/inc, allowing the PLC to capture small signal variations. For command generation, it carries an analog output rated at 5 V / 1 mA with a granularity of 19.5 mV/inc, which is adequate for proportional valve positioning. This combination lets the unit read low-level analog signals while also issuing a proportional output to external equipment. Position feedback is handled through Encoder Interface 1, which supports IndraDyn, Hiperface® formats, while a second interface accepts EnDat 2.1, 1 Vpp, or 5 V TTL signals.
Discrete control is delivered by the MD2 expansion, which offers 16 dedicated inputs and 16 transistor outputs, all galvanically isolated to prevent ground loops when wiring field devices. The isolated I/O helps separate field wiring from the control electronics during switching events. A synchronized SSI encoder can also be connected through the digital I/O option 3 module, letting the same board capture absolute position data. Service diagnostics are performed over the RS-232 port, which reaches 115 kBaud and can be extended with cables up to 15 m in length. For interlocking with external contactors, an S2 socket supplies relay contacts rated at DC 24 V / 1 A and uses a D-Sub 9-pin female connector. Motion supervision is supported by the controller’s integrated Safe Motion technology.
