Product Description:

The CSH01.1C-SE-EN1-NNN-MEM-L1-S-K1-FW control section is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed inside an IndraDrive power unit, this plug-in module serves as the central processor for axis regulation in industrial automation. It directs current, velocity, and position loops and provides the deterministic timing required for coordinated motion sequences on packaging lines, handling robots, and machine tools. Because it operates as the control section of the host drive, it handles motion commands and loop calculations within the same unit as the connected power stage.

Motion data exchange is managed through the digital fiber-optic interface SERCOS II, and the controller can close its internal current loop every 125 µs for responsive servo operation. The minimum bus cycle on the SERCOS ring is 1000 µs, allowing multi-axis synchronization without jitter across linked axes. Absolute position feedback can be emulated as SSI, while Encoder Interface 1 accepts Resolver/HSF signals and supplies the transducer with 8 V DC for feedback operation. Resolver excitation amplitude is 18.2 Vpp at a carrier of 4 kHz. A single ±10 V analog channel is available with a fixed output of 5 V for reference generation and related control tasks. The module’s MEM diagnostic port transmits status bits at 1 MHz and supports cable runs up to 40 m, allowing cabinet-to-machine wiring without repeaters.

During power-up, the section draws an inrush current of 4 A for a pulse lasting 100 ms, permitting standard control cabinet fusing. Once stable, overall consumption stays near 7.5 W, which simplifies thermal planning and allows passive convection cooling inside densely populated enclosures without added forced-air hardware. The integrated safety layer introduces a Starting Lockout function that inhibits torque until the drive receives a validated enable, preventing unexpected motion during maintenance or after fault recovery.
