Product Description:

The CDB01.1C-SE-EN1-EN2-NNN-NNN-NN-S-NN-FW control section is manufactured by Bosch Rexroth Indramat as part of the CDB Control Units series. The module mounts on an IndraDrive power stage and serves as the motion processor for one or two servo axes in automated machinery. It translates network commands into torque, speed, and position control while forwarding encoder feedback to higher-level controllers. This arrangement lets the control section coordinate feedback processing and command execution directly on the drive. By combining signal conditioning, real-time bus access, and safety logic in a compact card, it helps simplify cabinet layout in integrated drive systems.

Communication with higher-level motion controllers is handled through the SERCOS II protocol over a fiber-optic ring, delivering deterministic cycle times for interpolation tasks. The bus link supports synchronized data exchange between the control system and the drive during coordinated motion. Internally, the card draws 9 W of base power from the drive system. Machine sensors can be wired to dual-channel digital inputs rated at 24 V, 3 mA. Actuators such as valves are served by digital outputs rated at 24 V, 0.5 A. A Form-C relay contact supports 24 V DC at 1 A for hardware enable chains, and encoder port 1 handles resolver or HSF feedback while port 2 accepts EnDat 2.1, 1 Vpp, or 5 V TTL signals.

Analog diagnostics are available through an output channel that delivers 5 V, 1 mA for scope monitoring. The analog monitor output can be used to observe internal signals during setup or troubleshooting. The encoder 1 high-speed feedback rail supplies 8 V DC, while resolver excitation is held at 18.2 Vpp to support stable feedback signals across cable runs. An RS-232 port supports a maximum data rate of 115 kBaud for local access. The secondary feedback connector provides 5.0 V DC at 350 mA for EnDat or incremental encoders, so the reference supply remains stable during operation.
