Product Description:
Bosch Rexroth Indramat supplies the CSH01.1C-SE-ENS-NNN-NNN-S2-S-NN-FW control section as a member of the CSH Advanced Controllers series. The board is inserted into Rexroth drive racks to energize and monitor feedback devices that report rotary or linear position to the motion control loop. Acting as the interface between field sensors and the drive processor, it distributes regulated encoder power rails and processes resolver signals, ensuring deterministic position acquisition for packaging, material-handling, assembly, and CNC machining platforms.
Dedicated rails power optical and magnetic encoders at 12 VDC nominal, while an overvoltage ceiling of 12.3 VDC prevents accidental excursions from damaging sensor electronics. For TTL-level devices, the controller provides a second regulated line stabilized at 5.0 VDC; its allowable excursion tops out at 5.25 VDC to stay within typical logic thresholds. The 12-volt channel can deliver up to 500 mA, and the companion 5-volt output is rated for the same current, allowing multiple feedback heads to be daisy-chained without external power supplies. Combined, the outputs are limited to 6 W, and grouping both voltage domains on a single card simplifies wiring harnesses while keeping encoder return currents on a short, low-impedance path that minimizes signal distortion during rapid axis movements.
The resolver channel is isolated from the encoder rails and excites its windings at 8 kHz, a carrier that offers adequate temporal resolution while avoiding audible noise. A differential amplitude of 10 Vpp is generated so the sine and cosine signals remain clean after transmission through long motor cables. These parameters let the resolver coexist on the same backplane without crosstalk into the low-level encoder tracks. The selected limits balance measurement accuracy with component life and support electromagnetic compatibility during operation.
