Product Description:

The Bosch Rexroth Indramat CSH01.1C-PL-ENS-ENS-MA1-NN-S-NN-FW is a single-axis motion and logic controller in the CSH Advanced Controllers series. It serves as the central processing unit inside modular drive assemblies, coordinating drive commands, fieldbus data, and local I/O so that servo axes follow precise profiles in packaging machines, printing lines, and material-handling cells. By integrating programmable control with built-in analog and digital interfaces, the unit reduces the need for separate PLC hardware and streamlines cabinet wiring. It can also process machine-level logic while exchanging data with the surrounding drive system in real time.

At the hardware level, the controller draws a base power of 7.5 W, so standby consumption has minimal impact on control-cabinet heat dissipation. During startup, the supply must withstand an inrush of 4 A for up to 100 ms, after which current falls back to nominal levels. Sixteen optically isolated digital inputs are sensed at 24 V / 3 mA, while transistor outputs can each source up to 500 mA for solenoids or indicator lamps. The MA1 plug-in module adds two differential analog inputs and two analog outputs, and these signals span ±10 V for direct connection to torque or pressure sensors without external scaling.

The MA1 channels digitize signals with 12-bit resolution, and on-board converters generate voltage steps of 19.5 mV per increment for fine setpoint control. A parallel bus presents 16 inputs / 16 outputs to neighboring drives, reducing network latency when synchronizing high-speed axes. Two probe inputs capture edge-triggered positions for registration functions, while a form-C relay rated at 30 VDC / 1 A can switch clutch valves or safety interlocks. Diagnostic links use an RS-232 port that reaches 115 kBaud over cables up to 15 m, providing parameter access without occupying the main fieldbus.
