Product Description:

The CDB01.1C-ET-EN2-EN2-NNN-NNN-L2-S-NN-FW is a plug-in control section manufactured by Bosch Rexroth Indramat for the CDB Control Units series. Installed on an IndraDrive converter, it supplies real-time processing, I/O management, and network connectivity so the attached power module can regulate servomotors and actuators in automated machinery, conveyor zones, and packaging equipment. Its task is to accept fieldbus data, monitor feedback devices, and issue finely timed current commands that keep motion axes synchronized within a multi-axis industrial automation cell.

The control section includes 1 analog input for sensor feedback and 2 analog outputs that can transmit reference values to external regulators. Each analog output steps in increments of 19.5 mV/inc, allowing fine voltage scaling when driving proportional valves or analog speed references. Internal loops are refreshed on a 125 µs current control cycle, so torque commands reach the motor multiple times within a millisecond. Up to 22 digital inputs and 4 digital outputs are available through the onboard terminal strip, giving the drive direct access to limit switches, enable lines, or status lamps without an auxiliary PLC. Multi-Ethernet communication allows selection of PROFINET, EtherNet/IP, or standard TCP/IP, while an RS-232 service port supports configuration at data rates up to 115 kBaud.

The EN2 encoder interface is powered by an onboard module that dissipates 6 W, draws 350 mA, and is stabilized at 5.0 VDC; it supports EnDat 2.1, 1 Vpp, and 5 V TTL signals so the drive can read absolute or incremental feedback devices. A separate ET module consumes 2.2 W and places the Ethernet transceiver on the rear plane; its electrical layer follows the 100Base-TX standard and accepts shielded twisted-pair runs up to 100 m. For personnel safety, the hardware provides the certified Safe Torque Off function, which removes drive energy without altering application parameters.
