Product Description:

The CSH01.1C-PB-ENS-EN2-NNN-S2-S-XP-FW control section is produced by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. It is a modular drive controller component that hosts the main processor, fieldbus interface, and dual encoder channels used for axis control in automated machinery. Within an Indramat drive stack, this section supervises motion, exchanges real-time data over fieldbus, and applies Safe Motion functions that allow controlled stops and speed monitoring during machine operation.

Electrical loading on the section is modest because its base consumption is 7.5 W, so thermal contribution inside the cabinet remains low. The analog input channel presents 160 kΩ of resistance, which helps minimize loading on external sensors connected to the controller. Each digital input registers the ON state once the signal exceeds 15 V, whereas the sourcing digital outputs can supply up to 500 mA to drive contactors or indicator lamps. During power-up, the unit draws an inrush current of 4 A, which must be considered when selecting circuit protection. For control communication, it relies on PROFIBUS, giving deterministic cyclic data exchange with higher-level PLCs through its onboard 9-pin female D-Sub connector.

The section supports two independent encoder inputs. Interface 1 is labeled ENS and distributes a regulated 12 V supply to the sensor, while Interface 2, identified as EN2, accepts signals formatted as EnDat 2.1, 1 Vpp, or 5 V TTL. When sense lines are used, the EN2 channel permits cable lengths up to 75 m; without sense wiring, the limit falls to 50 m. Internal watchdog logic observes control pulses and limits them to 100 ms to avoid timeout faults. A service RS-232 port is available, with data rates as high as 115 kBaud, allowing rapid parameter uploads.
