Product Description:

The CSH01.1C-S3-EN2-ENS-NNN-S1-S-NN-FW is a single-axis control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed inside an IndraDrive power module, this board governs servo drive operation by executing motion sequences, managing feedback, and exchanging data with higher-level automation layers. Its role in industrial automation is to translate fieldbus commands into precise velocity, position, and torque references for connected motors while also collecting diagnostic information for the machine control system.

For analog command processing, the board provides a differential input range of ±10 V. The channel has an input impedance of 160 kΩ, so upstream signal sources are not heavily loaded. Position and speed loops benefit from the converter step size of 1.23 mV/inc, allowing fine setpoint resolution. The reference output channel delivers 5 V at up to 1 mA and reports feedback with a granularity of 19.5 mV/inc. Encoder socket X4 accepts EnDat 2.1, 1 Vpp, or 5 V TTL signals, and a second port reads IndraDyn or HIPERFACE sine-cosine tracks. Drive coordination with external PLCs is handled over the deterministic SERCOS III master interface, while an RS-232 port remains available for service access.

Machine safety is addressed by the integrated Safety Technology I/O package. A D-Sub 9-pin female connector carries dual-channel enable loops that accept logic levels of 24 V / 3 mA. When a safe stop condition is met, two solid-state switches can interrupt power on the output side with a capacity of 24 V / 0.5 A. The safety electronics draw power from a DC 24 V auxiliary rail, and current demand can rise to 1.6 A during startup and fault reset sequences. These dedicated circuits allow the controller to meet category requirements without burdening the main control loops or their analog and encoder paths.
