Product Description:
Bosch Rexroth Indramat builds the CSH01.1C-NN-EN1-MA1-MD1-S1-S-NN-FW as part of the CSH Advanced Controllers series. This single-axis motion controller plugs into an IndraDrive power unit and handles real-time positioning, speed regulation, and process monitoring in automated machinery. It combines encoder evaluation, analog conversion, relay switching, and discrete I/O on one controller card, creating the hardware link between a PLC and the drive power section. That arrangement allows motion commands, feedback signals, and machine status data to be processed within the same control platform.
The analog front end presents an input resistance of 160 kΩ, so connected sensors experience minimal loading and signal distortion is kept low. For incremental feedback, the EN1 interface provides 18.2 Vpp sinusoidal signals and excites the encoder at 4 kHz, supporting accurate interpolation of position information. The MA1 mezzanine offers two analog input channels with a resolution of 12 bit and two matching analog outputs for process control, allowing the controller to read machine variables and issue reference signals. A built-in 5 V rail can source up to 500 mA for transducers or optocouplers, which reduces the need for a separate auxiliary supply. Twelve digital inputs in the MD1 group accept 24 V status signals from field devices such as limit switches, sensors, and light curtains.
The relay block supplements the solid-state channels and can switch loads of up to 1 A over a mechanical life of 1×10⁸ cycles, provided the contact voltage remains within 30 V DC. The S1 header delivers auxiliary power up to 1.6 A and also includes four mode-selection inputs used for operating states and setup functions. Actuator commands leave the board through 8 discrete outputs in the MD1 section, giving the cabinet direct control over solenoids, contactors, and indicator lamps. This I/O mix lets the controller manage local logic and pass deterministic command and status signals without requiring additional interface hardware.
