Product Description:

Bosch Rexroth Indramat manufactures the CSH01.1C-SE-EN1-NNN-MEM-S1-S-NN-FW modular control card for the CSH Advanced Controllers series. The board inserts into Rexroth drive racks and supervises coordinated axis motion, safety inputs, and status reporting for automated production cells. It executes position loops while forwarding deterministic data to upper-level PLCs, allowing packaging lines, gantry robots, and material-handling stations to run synchronized cycles. Its compact build and modest thermal load permit installation in tight electrical enclosures, and multiple cards can be grouped to scale with growing machine layouts.

The controller’s base power draw is 7.5 W, limiting cabinet heat generation during continuous duty. Motion commands and diagnostic telegrams are exchanged over the SERCOS II fiber-optic ring; this interface starts with a 4 µs inrush pulse that reaches 4 A and lasts up to 100 ms before settling to normal current levels. For legacy follow-axis drives, the board provides encoder emulation at a carrier of 1 MHz, supporting both incremental and SSI formats so external drives can close their internal loops. The dedicated resolver and HSF inputs accept 4 kHz carrier signals, while the resolver supply is 18.2 Vpp to keep sensor excitation within safe limits. A single-line panel display presents node addressing and error codes locally, and RS-232 maintenance access reaches 115 kBaud across cable runs up to 15 m. A D-Sub 9 female connector exposes hard-wired safe-torque-off contacts to meet machine safety requirements.

Distance-critical feedback chains can be bridged with an emulation cable length of 40 m. The high-speed feedback port delivers hall sensor excitation at 8 VDC. The resolver excitation frequency of 4 kHz aligns with typical rotary transformer windings to minimize phase error. The optical ring can be clocked to a maximum of 16 MBaud when high axis counts demand shorter update cycles.
