Product Description:

The CDB01.1C-SE-ENS-ENS-EN1-EN1-S2-S-NN-FW is a plug-in control card in the CDB Control Units series from Bosch Rexroth Indramat. Installed inside an IndraDrive power section, it forms the processing core that coordinates drives, interprets feedback, and exchanges motion data with higher-level PLCs. By integrating these tasks on one board, the product streamlines multi-axis automation in packaging, printing, and handling systems where precise positioning, coordinated motion, and tight cycle times are required.

This module governs a 2-axis arrangement while drawing only 9 W of base power, easing cabinet cooling demands. Command and status frames move over the optical SERCOS II interface, and closed-loop updates can be executed every 1000 µs to maintain velocity and current control accuracy. On power-up, the board withstands an inrush of 6 A before settling to steady consumption. Two front slots are populated with ENS encoder cards for incremental feedback, and two more carry EN1 cards for absolute position sensing. Resolver inputs operate at 4 kHz, and dedicated supplies feed each transducer. The internal logic also filters enable signals and accepts command pulses that stay below the 60 ms maximum width used for fast-stop channels.

Digital outputs source up to 500 mA, which is sufficient for brake coils or relay drivers, and built-in safety complies with Safe Motion, allowing SIL-rated monitoring without external hardware. A maintenance port communicates through RS232 at 115 kBaud for local setup and diagnostics, while the backplane provides ENS encoders with a regulated 12 V supply. Additional sensor heads receive 250 mA at 8 V DC, and resolver excitation is delivered as 18.2 Vpp at 4 kHz to maintain signal integrity. These electrical allowances support feedback devices, output loads, and safety functions across both axes during normal drive operation.
