Product Description:
The CSH01.1C-PB-ENS-EN2-NNN-S2-S-NN-FW control section is produced by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. As a plug-in drive controller card, it coordinates command, monitoring, and diagnostic functions for an individual servo axis inside IndraDrive power units. This arrangement separates motion control tasks from the power stage inside the drive assembly. By translating high-level automation commands into real-time motion profiles, the module forms the interface between the machine PLC and the inverter stage, ensuring deterministic positioning and speed regulation in industrial automation lines.
The card is designed for single-axis operation, so it supervises one mechanical axis with dedicated feedback and safety channels. Field communication is handled through PROFIBUS, and the integrated bus driver supports rates up to 12 MBaud while using a D-Sub 9-pin female connector for network cabling. Under idle conditions, the electronics draw only 7.5 W, yet they tolerate a 4 A inrush when the drive is energized. A 100 ms maximum pulse width on the fast inputs accommodates drive-based positioning commands that require narrow gating. The card includes Safe Motion functions, and the safety I/O can source or sink 1.6 A for external relays. A separate relay inside the card is rated for 24 V DC at 1 A to switch brakes or contactors.
Feedback resources are split across two encoder channels. Channel one can supply 11.6 V DC at up to 500 mA, allowing absolute encoders with active electronics to be powered directly from the card. A secondary port provides 5.0 V DC with a continuous limit of 350 mA for TTL-based incremental devices. Parameterization and service access are available through the RS232 port, which uses a MiniDIN 8-pin female connector and supports cable lengths up to 15 m. This service connection allows direct diagnostics without affecting fieldbus traffic.
