Product Description:

The CSH01.1C-SE-ENS-EN1-NNN-NN-S-NN-FW control section is a plug-in unit manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. This hardware forms the central processor and signal-conditioning layer inside an IndraDrive modular inverter, handling real-time axis regulation, feedback processing, and fieldbus communication required in automated assembly cells, packaging lines, and material-handling equipment. High-speed data exchange is maintained at a line rate of 16 MBaud, supporting the fast communication cycles used in multi-axis systems.

At the analog end, the module supplies an output channel rated at 5 V with a granularity of 19.5 mV/inc, allowing fine reference generation for external amplifiers or process sensors. Power drawn by the logic and interface circuitry is limited to 7.5 W, so thermal load inside the drive cabinet remains low. One protected digital output can source up to 0.5 A, which is sufficient for actuating relays or light indicators. Bus coupling to drives and higher-level controllers is realized through SERCOS II on an optical ring, and the fiber link also transports synchronization telegrams to the internal position loop. For the primary feedback channel (EN1), the board provides 8 V at 250 mA, excites the resolver with a 4 kHz carrier, and returns 18.2 Vpp signals for angle decoding.

During power-up, the capacitive input stage momentarily draws 4 A for a duration of 100 ms, so the upstream supply must tolerate that inrush period. The secondary encoder supply (ENS) provides 11.6 V with 500 mA capability and filters position signals with a cutoff of 500 kHz to suppress noise while preserving high-resolution measurement. A 4 µs probe pulse is available for zero-latency capture of position events. This allows the controller to register fast external triggers without waiting for a slower software scan.
