Product Description:

Bosch Rexroth Indramat builds the CDB01.1C-ET-ENS-ENS-ENS-S2-S-NN-FW as a plug-in control board inside the CDB Control Units series. The board functions as the central signal-processing layer of an IndraDrive system, translating fieldbus, encoder, and safety information into real-time drive commands. By combining analog references, high-speed digital feedback, and Ethernet networking on one compact card, it supports coordinated motion sequences, speed loops, and axis diagnostics across a broad range of automated machinery. Its primary purpose in industrial automation is to reduce cabinet wiring, simplify setup, and provide deterministic control paths between the motion controller and power stage.

The control board’s baseline power draw is 9 W, so auxiliary supplies need only a minimal margin for standby functions. During initial charging of internal capacitors, the inrush reaches 6 A, which influences circuit-breaker selection. Two analog channels can source up to 5 V at 1 mA, giving the drive a precise reference for torque or velocity commands without overloading downstream inputs. Encoder signals enter through a D-Sub 15-pin connector that delivers 11.6 VDC sensor power and is filtered to a cutoff of 500 kHz to suppress high-frequency noise. A serial diagnostic interface communicates at 115 kBaud, and captured position pulses as long as 60 ms are recognized, allowing low-speed homing routines to remain accurate.

Network and safety resources are located on the right edge of the board. The Ethernet interface uses an RJ-45 8-pin jack and operates on the 100Base-TX standard; it supports cable runs up to 100 m so the unit can be placed far from the nearest switch without repeaters. Fast digital feedback is accepted on the TTL channel up to 400 kHz, matching servo encoders with high line counts. A dedicated D-Sub 9-pin connector routes safe-torque-off commands, while the isolated safety driver can sink or source up to 0.5 A to external interlocks.
