Product Description:

The CSH01.1C-CO-ENS-EN2-NNN-NN-S-NN-FW is a single-axis control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in IndraDrive modular drive stacks, the unit processes motion commands, fieldbus traffic, and sensor feedback to regulate connected servo or spindle axes in industrial automation lines. It serves as the interface between higher-level PLCs and power stages, converting machine instructions into precise current and position setpoints while supervising safety and diagnostic channels. This arrangement allows the control section to handle command processing and feedback evaluation within the drive system.

Two differential analog inputs are monitored through an input impedance of 160 kΩ, minimizing loading on upstream process transducers. The section drives reference signals through its analog output channel, which is rated for a load of 5 kΩ and delivers up to 5 V, 1 mA. Logic-level interaction is handled by sink-type digital inputs that expect 24 V, 3 mA, while control relays or brake valves can be energized by digital outputs that supply 24 V, 0.5 A. A discrete 124 Ω, 1%, 200 mW terminator is integrated on the CoBus port so the CANopen or DeviceNet fieldbus can be terminated locally when the controller is installed at the network boundary.

Position feedback resources include an EnS interface that supplies 11.6 V at 500 mA and an En2 port that provides 5.0 V at 350 mA for incremental or absolute encoders, allowing the module to power two sensor systems at the same time. During power-up, the unit can draw up to 4 A of inrush current, yet steady operation requires only 20.5 W of controller power. Internal timing permits probe captures with a maximum pulse width of 100 ms. High-speed touch-trigger events can be registered with a probe pulse width of 4 µs, and auxiliary switching uses a 24 V DC relay contact rated at 1 A.
