Product Description:

The CSH01.1C-S3-ENS-ENS-MA1-NN-S-NN-FW is a plug-in control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed on an IndraDrive power base, it provides the motion-processing core that interprets encoder data, executes servo algorithms, and generates drive commands. In conveyor cells, packaging lines, and press automation, the unit converts high-level setpoints from a PLC into timed torque and position profiles for one or more axes.

Its two analog input channels accept a full-scale range of ±10 V, allowing direct connection of load cells, potentiometers, or external speed references. Each input is digitized at 12-bit resolution, giving 4,096 steps across the span. The inputs are wired as two differential channels to reject common-mode noise. Matching analog outputs reproduce command or monitor values over the same range with identical resolution. Two encoder ports accommodate IndraDyn sin-cos, Hiperface, 1 Vss, or TTL feedback for simultaneous motor and load position tracking. The section draws only 7.5 W of base power and exchanges cyclic data over Sercos III for deterministic axis coordination.

For transient power-up, the module tolerates a typical inrush of 4 A, so line fusing can be sized accordingly. Output control pulses generated by its onboard processor may extend to a maximum width of 100 ms, supporting slow-speed jog or dwell functions without external timing hardware. Mechanically, the housing measures 49.5 mm in width and 241 mm in height, with a depth of 103 mm, permitting dense side-by-side stacking inside a 300 mm-deep cabinet. Field wiring is completed through the MA1 15-pin D-Sub female connector, and the design is delivered without a safety option, so emergency-stop monitoring must be handled by other devices in the drive chain.
