Product Description:

The CSH01.1C-PL-ENS-EN1-NNN-NN-S-NN-FW belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. It is a control section that docks onto IndraDrive power units to execute axis positioning, handle feedback processing, and pass set-point data to the drive. Within an automation cell, it serves as the logic centerpiece that translates motion commands from the PLC into precise drive-level actions, coordinating encoders, analog references, and high-speed digital I/O required for servo regulation.

The analog front end presents an input impedance of 160 kΩ, so external sensors see only a minimal load. A programmable analog output delivers reference voltages of 5 V at 1 mA for drive or process signaling, while the module’s own base demand is limited to 7.5 W. Command data is exchanged over a Parallel Interface, giving deterministic timing between the controller and the host PLC. For single-turn feedback devices, the first encoder socket supplies 12 V and accepts IndraDyn, HIPERFACE, or 1 Vpp sine-cosine signals. Sixteen programmable logic digital inputs and sixteen digital outputs enable direct wiring of limit switches and actuator coils, and the relay contact can switch 24 VDC at 1 A whenever galvanic isolation is preferred.

A second encoder port furnishes 8 V to resolver or HSF transducers, with resolver excitation set at 18.2 Vpp and a carrier frequency of 4 kHz for noise-immune angle detection. During power-up, the control board draws a peak of 4 A, after which inrush control hands over to the steady 24 V cabinet supply. Fast position-latch events are supported by input pulse widths down to 100 ms, ensuring reliable capture of registration marks. Configuration and service access are provided through a serial link that follows the RS-232 standard, augmenting the parallel bus with a simple point-to-point channel for parameter uploads and diagnostics.
