Product Description:

Bosch Rexroth Indramat's CSH01.1C-CO-ENS-NNN-MA1-L2-S-NN-FW is a plug-in control unit in the CSH Advanced Controllers series. Installed in an IndraDrive stack, it supervises motion loops, exchanges fieldbus data, and applies safety logic for connected servo axes. The card links process sensors, encoder feedback, and higher-level PLCs to maintain coordinated movement in automated machinery. Because the control section is plug-in, it handles command processing separately from the power stage within the drive assembly.

The module supplies two differential analog input channels that accept a ±10 V signal range. Each input is converted with 12-bit resolution, giving 4,096 steps for precise scaling of speed or pressure references. It also provides two analog output channels, so proportional valves or inverters receive voltage commands across the same ±10 V range. This arrangement allows the controller to interface with external transducers and command devices without extra conversion hardware. For deterministic digital networking, the unit supports CANopen / DeviceNet, allowing cyclic data exchange with PLCs, remote I/O, and operator panels. Shield termination occurs on the X60 five-pole spring terminal, and a 15-pin D-Sub MA1 socket carries enable, ready, and reference lines. Encoder positions are accepted through IndraDyn, Hiperface, 1 Vss, or TTL interfaces, so both absolute and incremental feedback can be processed.

Compact dimensions of 241 × 49.5 × 103 mm simplify installation in densely populated racks. The encoder ports supply 12 V, removing the need for external sensor power while keeping cable runs short. Drive safety is handled by Safe Torque Off; when the STO input is asserted, internal circuitry blocks gate signals to guarantee a torque-free state. A feedback contact rated at 24 V and 1 A confirms the action, and the monitored input path draws 3 mA at 24 V. Service access is isolated from field communication by the dedicated RS-232 interface, allowing parameter edits without disturbing the CAN bus. Separating service access from the network helps preserve active bus communication during local setup or diagnostics.
