Product Description:

The CSH01.1C-SE-EN2-NNN-MEM-S1-S-NN-FW control section is produced by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. Designed for mounting on an IndraDrive power module, this unit functions as a central motion controller and field-level interface in automated equipment. It orchestrates axis commands, manages encoder feedback, and exchanges real-time data with higher-level PLCs to keep coordinated drives operating within programmed trajectories.

Electrical loading on the board is modest; it consumes only 7.5 W from the control backplane and is supplied by a regulated DC 24 V logic rail. During power-up, the circuitry can draw a base inrush of 4 A, yet the surge is limited to a pulse width of 100 ms to avoid tripping the upstream supply. Communication with the drive bus is handled through SERCOS II, giving deterministic 62.5 µs cycle times and synchronized data exchange. A separate RS232 service port permits local diagnostics without disturbing the real-time channel. The section is galvanically isolated from the emulation outputs, and its internal memory can toggle marker bits at rates up to the 1 MHz limit used for the MEM channel.

Feedback handling is comprehensive. The primary encoder interface accepts EnDat 2.1 / 1 Vpp / 5 V TTL signals, and the board can emulate incremental or SSI formats for downstream devices. An encoder sense line is required so the controller can verify correct cable polarity before enabling motion. The secondary supply rail for transducers is held at 5 V, and the emulation drivers sustain pulse streams up to 1 MHz when MEM resources are active. Integrated Safety Technology I/O supports category-oriented stop functions, allowing the drive to meet machine safety directives without external relays. All encoder and safety circuits are galvanically isolated from the logic core, while service commands can still be issued over the RS232 port.
