Product Description:

The CDB01.1C-S3-ENS-EN2-EN2-ENS-S2-S-NN-FW is a controller module built by Bosch Rexroth Indramat for use in IndraDrive automation platforms. As a member of the CDB Control Units series, it occupies the control section of a drive. It processes feedback, fieldbus traffic, and safety signals so that servo axes can be commanded with deterministic timing in industrial machinery.

Its axis configuration is Double-Axis, allowing one board to coordinate two servo channels and reduce panel footprint. Drive and encoder logic are powered from a DC 24 V control supply that stays active during mains outages to preserve communication. Command data and cyclic setpoints enter through a SERCOS III interface, giving the module tight synchronization across the motion network. For local signaling, it offers four transistor outputs that can source up to 500 mA total, which is sufficient for contactors or status lamps. Diagnostic access is provided by the built-in RS232 service port. Functional safety is handled through the integrated Safe Motion package, which monitors speed and position without external relays. Other resources include a 9 W base power draw, an RJ-45 8-pin connector for Ethernet media, and a secondary encoder channel for EnDat 2.1, 1 Vpp, and 5 V TTL signals that can supply 350 mA at 5 V to the sensor head.

During start-up, the control electronics follow the Ethernet physical layer of IEEE 802.3, ensuring standard cabling and switch compatibility on the plant floor. The control input can tolerate a typical inrush of 6 A and a pulse width up to 60 ms, so the power source must support short-term current demand at turn-on. A separate encoder socket supplies 12 V for IndraDyn or HIPERFACE devices and routes 1 Vpp sine-cosine signals back to the controller. Another channel handles TTL feedback so each axis can accept mixed sensor technologies.
