Product Description:

The CSH01.1C-NN-EN2-NNN-MEM-S1-S-NN-FW is a single-axis controller module from the CSH Advanced Controllers series produced by Bosch Rexroth Indramat. It plugs into IndraDrive power sections and executes position, velocity, and current loops for servo motors used in industrial automation cells, pick-and-place gantries, and packaging machinery. Field-level signals enter through analog, encoder, and relay ports on the front edge of the card, allowing the module to translate external feedback into deterministic motion commands for the connected drive.

The analog interface presents an input impedance of 160 kΩ, so standard process instruments can drive it without loading errors, and it accepts a differential range of ±10 V for scaled speed or torque references. Downstream loads must exceed a minimum resistance of 35 Ω to avoid output clipping during signal transfer. The encoder socket can source up to 350 mA for incremental or absolute transducers, while the MEM high-speed feedback channel supports cable runs to 40 m and transfers differential data at up to 1 MHz. The complementary channel supports the same maximum square-wave frequency, helping preserve clean digital edges during feedback transmission across the specified cable length.

The option boards draw modest power from the backplane: En2 requires 6 W, the MEM interface requires 2 W, and the S1 safety monitoring board requires 1 W. The En2 port operates from a nominal supply of 5 VDC, delivered by the controller to the encoder through shielded leads. A form-C relay is available for ready or fault signaling and is rated at 24 VDC, 1 A for switching auxiliary logic loads. For sinusoidal measurement, the card applies a 1 Vpp reference, filters inputs at a 500 kHz cutoff, and digitizes them with 12-bit resolution; the front end’s 120 Ω input resistance matches typical coax sources and supports stable signal integrity without external conditioning.
