Product Description:

The CDB01.1C-ET-EN1-EN1-NNN-MEM-L2-S-NN-FW is a control section manufactured by Bosch Rexroth Indramat for the CDB Control Units series. Installed on a drive controller base, it processes encoder data, executes motion commands, and links each axis with higher-level PLCs. Within an automation cell, the unit issues velocity, torque, and position references so that connected servo inverters follow coordinated profiles in packaging, handling, and assembly equipment.

It supports 2 synchronized axes and communicates with the factory network through the Multi-Ethernet interface. The Ethernet port meets the 100Base-TX standard and uses an 8-pin RJ-45 connector for direct Cat-5e wiring. For third-party feedback devices, it produces digital emulation pulses up to 1 MHz, supplying high-resolution replica signals to external counters or safety relays. Native feedback handling is flexible, and the board accepts 2 Resolver/HSF inputs, allowing traditional resolvers and high-speed sine-cosine sensors on the same controller. Functional safety is embedded, and a hardware channel executes Safe Torque Off, removing drive power when an emergency stop or guard interlock is triggered without software intervention.

The encoder emulator can output Absolute + Incremental formats simultaneously, so motion controllers that need binary position words and legacy A-B-Z tracks are both supported. High-speed feedback inputs are conditioned with a cutoff frequency of 100 kHz, preventing aliasing while tracking fast rotor dynamics. These channels are powered from an 8 VDC rail that can deliver 250 mA, whereas resolver excitation is generated separately at 18.2 Vpp and 4 kHz with a 70 mA limit. Double shielding on the MEM cable minimizes electromagnetic coupling between low-level control signals and the power stage. This arrangement allows one control section to support mixed feedback devices on compact machine layouts.
