Product Description:

The CSH01.1C-CO-EN2-NNN-MD1-NN-S-NN-FW is a single-axis control section supplied by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. Installed on a compatible power section, the board supervises position, velocity, and drive diagnostics in automated machinery and material-handling cells. It communicates with higher-level PLCs through embedded fieldbus interfaces and converts motion profiles into encoder-referenced commands for the inverter stage, allowing deterministic multi-axis coordination on production lines.

Two differential analog inputs exhibit a resistance of 160 kΩ, which minimizes load on upstream process transducers. Each analog output has a conversion value of 19.5 mV/inc, which supports precise torque trim signals. A base power draw of 7.5 W keeps internal heat generation low, while the integrated termination network of 124 Ω with 1% tolerance at 200 mW supports controlled impedance on the CAN line. The CANopen channel supports up to 127 nodes, and a DeviceNet channel is included for mixed-protocol installations. The MD1 add-on provides 12 digital inputs, 8 digital outputs, and two probe inputs for fast position-trigger capture. During power-up, the control section withstands an inrush current of 4 A.

Field wiring lands on a 5-pin spring terminal, allowing tool-free connection to the embedded control communication bus. When DeviceNet is selected, a maximum of 64 nodes can be addressed without external repeaters, and individual telegrams may include pulses up to 100 ms wide. The encoder interface accepts EnDat 2.1, 1 Vpp, or 5 V TTL signals and supplies the transducer with 5 V. Internal relays are rated for 24 V DC, 1 A, enabling direct actuation of contactors or drive-safe circuits. Eight transistor outputs from the MD1 stage switch auxiliary loads under internal control.
