Product Description:
The CDB01.1C-SE-EN2-EN2-NNN-MA1-NN-S-NN-FW is a plug-in control section manufactured by Bosch Rexroth Indramat for the CDB Control Units series. Mounted on a compatible power section, it forms the command layer of an IndraDrive system by converting fieldbus messages and sensor feedback into precise drive commands. The board is used in automation cells where coordinated multi-axis positioning, velocity regulation, and analog reference handling are required for machinery such as pick-and-place gantries, packaging lines, and printing equipment.
Communication with the motion controller is handled through the Sercos II interface over a fiber-optic medium that operates at 16 MBaud, allowing deterministic exchange of position, control, and diagnostic data. Two EN2 encoder ports accept EnDat2.1, 1 Vpp, and 5 V TTL feedback formats, and each port filters differential sine signals up to 500 kHz while registering amplitudes between 0.8 and 1.2 Vpp. The section also provides one analog voltage channel with a range of 0 to +5 V at 8-bit resolution, while two additional MA1 channels supply analog references at 12-bit depth. The voltage input path withstands ±10 V and presents a 160 kΩ input resistance, which helps prevent overload on upstream control cards.
The internal electronics are powered from an auxiliary supply of DC 19 to 30 V and draw up to 1.1 A under full I/O load. A dedicated encoder rail outputs 5.0 V with a continuous delivery capability of 350 mA, providing stable power for attached incremental or absolute sensors. Separate analog channels allow the control section to process external speed-demand signals and command torque-mode inverters, while the paired feedback connections pass position data to the drive without additional splitter hardware. Twelve-bit conversion on the MA1 paths supports fine command granularity during closed-loop control.
