Product Description:
The CDB01.1C-PB-EN1-EN1-EN2-EN2-S2-S-NN-FW belongs to the CDB Control Units series manufactured by Bosch Rexroth Indramat. Installed on top of a power section, this control unit supplies the logic, feedback handling, and fieldbus connectivity needed to synchronize multiple drives within an automated line. It fits between a higher-level PLC and the motor inverter, translating network commands into axis-specific instructions for precise motion control in industrial automation.
The unit exchanges cyclic data with the master controller through PROFIBUS-DP, and its dedicated PB board draws only 2 W to minimize thermal load. Internal logic circuits require 9 W of control power, and the design manages 2 controlled axes with separate encoder channels. Each digital output group can source up to 500 mA, supporting contactors or signaling lamps without external relays. Encoder slot EN1 provides an 8 V DC sensor supply, a pair of interfaces, and 6 W of module power, while EN2 uses the same interface layout and power draw and adds its own 5.0 V DC line for TTL encoders. All low-voltage rails are monitored by onboard supervision circuits to help prevent undervoltage errors.
Start-up demands are managed by an inrush limiter that caps input surge to 6 A for a maximum duration of 60 ms, helping protect cabinet fuses as capacitors charge. Serial diagnostics are available through an RS-232 port that reaches 115 kBaud, allowing parameter backups and service access without occupying the fieldbus. The EN2 slot can deliver 350 mA at 5.0 V DC to incremental encoders, and its outputs are galvanically isolated from the control logic. Integrated SafeMotion technology provides the safety layer, and the presence of Safe Motion supports STO and safe-speed functions without external relays.
