Product Description:

The CDB01.1C-ET-EN2-EN2-ENS-ENS-S2-S-NN-FW is a control unit manufactured by Bosch Rexroth Indramat and belongs to the CDB Control Units series. As a modular drive controller component, it coordinates feedback, fieldbus traffic, and safety inputs so motion axes can be synchronized inside an automation cell. Installed inside an IndraDrive power section, the board provides signal conditioning and network access necessary for precise speed, torque, and position loops used on packaging lines, gantries, and material-handling machines. This arrangement keeps command, feedback, and safety processing on one board, which helps the drive respond consistently during coordinated multi-axis motion.

During operation, the controller draws a base power of 9 W, allowing compact thermal design. All logic circuits are supplied from a DC 24 V control bus, and the typical inrush current reaches 6 A when the unit is energized. Network traffic is handled through a Multi-Ethernet interface that supports the 100Base-TX physical layer, so drive parameters can be exchanged over PROFINET, EtherNet/IP, or Sercos over Ethernet. Two diagnostic relays rated for DC 1 A at DC 30 V provide galvanically isolated fault signaling, while four digital outputs share a maximum channel current of 500 mA with a cumulative limit of 1000 mA. That combination supports standard control wiring and integration with other low-voltage cabinet devices.

For position feedback, the board offers two encoder channels. The first channel accepts EnDat 2.1 / 1 Vpp / 5 V TTL signals, while the second accommodates IndraDyn / HIPERFACE / 1 Vpp feedback, letting mixed-sensor machines run without extra interface cards. The paired encoder interfaces let the control section work with common motor feedback formats without separate conversion hardware. Safe-motion functions are enabled by integrated Safe Motion capability and accessed through a D-Sub 9-pin female safety connector that brings in external enable chains. The ET communication plug adds 2.2 W to the consumption budget and supports a maximum pulse width of 60 ms for time-critical telegrams.
