Product Description:

The CDB01.1C-ET-ENS-EN2-NNN-NNN-S1-S-NN-FW is a plug-in control section built by Bosch Rexroth Indramat for the CDB Control Units series. Mounted on IndraDrive power sections, this card supplies drive command processing, fieldbus access, and encoder evaluation for one axis of motion. It acts as the interface between higher-level PLCs and the inverter stage, allowing precise velocity, torque, and position regulation in industrial automation cells such as pick-and-place gantries, packaging lines, and material handling systems.

The card draws a base power of 9 W during standby and offers one analog output channel that sources 1 mA at a nominal 5 V. Each increment on this channel represents 19.5 mV, giving fine resolution for speed or current references. Network connectivity is handled by a Multi-Ethernet interface that supports EtherNet/IP, PROFINET, and SERCOS over copper, and the physical layer is 100Base-TX. Primary encoder feedback can be IndraDyn, HIPERFACE, or 1 Vpp sinusoidal, and a second port accepts EnDat 2.1, 1 Vpp, or 5 V TTL signals for dual-loop control. The unit’s digital outputs are grouped together and can deliver up to 1000 mA in total, while any single logic output is limited to 500 mA.

During power-up, typical inrush current reaches 6 A with a maximum pulse width of 60 ms, values used when sizing cabinet fusing and contactors. The separate safety supply conforms to the Safety I/O option; it may draw up to 1.6 A and supports internally switched outputs rated at 0.5 A each. An onboard relay rated at 24 V DC, 1 A provides force-guided contacts for STO or guard door circuits. Ethernet magnetics share the same supply but do not exceed the maximum stated output current of 500 mA. At full load, the module can supply auxiliary field devices while remaining within the stated inrush and output-current limits.
