Product Description:

The CDB01.1C-SE-ENS-ENS-EN2-EN2-S1-S-NN-FW is a plug-in control card produced by Bosch Rexroth Indramat for the CDB Control Units series. Mounted on an IndraDrive power section, it supervises axis control, signal conversion, and integrated safety in automated machinery. The card links the drive to higher-level PLC platforms, converts field commands into motion sequences, and delivers position feedback from multiple encoder formats to maintain closed-loop accuracy on the plant floor. This arrangement allows one control layer to handle motion, feedback processing, and safety-related response within the same drive assembly.

An analog input path with a resistance of 160 kOhm allows high-impedance process signals to be monitored without loading the source. The board can retransmit reference values through an analog output that supplies 1 mA at a nominal level of 5 V. Internally, logic and interface circuitry draw 9 W from the base board, and the supply must tolerate an inrush of 6 A when the drive first energizes. Control communication is handled over the real-time SERCOS II fiber-optic ring, ensuring deterministic transfers for velocity, torque, and diagnostic data. The interface layout supports stable signal exchange between the control section and the attached power stage during operating changes.

The unit offers eight parameterizable digital outputs, and each channel can source up to 500 mA, while the combined output group is limited to 1000 mA. A maximum inrush pulse of 60 ms indicates how long the elevated startup current may persist. Two encoder module sockets accept 2× IndraDyn/HIPERFACE 1 Vpp signals or 2× EnDat 2.1, 1 Vpp, and 5 V TTL feedback, and each encoder may draw 6 W from the board. Probe inputs recognize 5 V as logic low and 15 V as logic high, supporting edge-triggered position capture. For discrete actuator control, a relay contact rated at DC 24 V, 1 A is available. Integrated Safety Technology I/O allows local emergency stop chains and door interlocks to be wired directly to the card without external relays.
