Product Description:

The CSH01.1C-NN-EN1-MEM-MA1-S1-S-NN-FW control section is manufactured by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed inside an IndraDrive modular rack, the unit serves as the central processor that links power electronics with external sensors and actuators in automated machinery. It coordinates command signals, feedback data, and integrated safety so production equipment can maintain repeatable positioning, velocity control, and stop functions across multiple servo axes. Its compact form fits modular drive cabinets without changing the surrounding wiring.

Two differential ±10 V analog input channels are supplied by the MA1 board, and each channel is converted at 12-bit resolution for precise setpoint capture. The same board offers two ±10 V analog outputs that can drive external regulators, while the base layer provides 2 x 5 V / 1 mA reference outputs for potentiometers or light-load transducers. Feedback flexibility is high because the EN1 slot supports incremental and SSI absolute pulse streams, and its front end also accepts resolver and HSF sensors for different encoder types. All emulation paths are galvanically isolated and work without an external supply, which helps limit ground loops, and setup and diagnostics are accessed through an RS232 service port.

The S1 option equips the controller with Safety Technology I/O, and field wiring terminates on a 9-pin female D-Sub connector that simplifies continuity checks. Two safety inputs recognize signals at 24 V / 3 mA, and twin outputs can switch loads up to 24 V / 0.5 A for contactor control or zone muting. Because the card is delivered without separate fieldbus control communication, integration relies on the internal IndraDrive backplane. Through the encoder interface, it can directly control MHD and MKD motors, which allows legacy and newer axes to operate from the same drive platform.
