Product Description:

The CDB01.1C-S3-NNN-NNN-NNN-NNN-L2-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CDB Control Units series. Installed inside a drive controller rack, this unit governs two motion axes and exchanges real-time data with higher-level automation systems through its integrated SERCOS network. By coordinating setpoints, feedback, and safety signals, the control unit enables tightly synchronized positioning, speed, and torque regulation in industrial machines such as handling robots, packaging stations, and printing lines.

An axis capacity of 2 allows the device to orchestrate a pair of independent servo drives while still leaving room on the backplane for additional modules. Four user-assignable inputs or outputs, shown here as 4 combined I/O channels, support limit switches, probe triggers, or status lamps without external converters. Each analog feedback channel presents an input resistance of 160 kOhm, which is high enough to avoid loading precision sensors. Command and diagnostic telegrams move across the deterministic SERCOS ring in its third generation, identified here as SERCOS III, enabling cycle times appropriate for high-speed motion. When discrete signals must be driven, the digital outputs source up to 500 mA, permitting direct actuation of small relays or optical indicators.

The internal logic and field terminals are powered from a customary control voltage of 24 VDC. For brief inrush events, the I/O rail can draw as much as 1.1 A without auxiliary supplies. A maintenance port supports asynchronous serial communication up to 115 kBaud, so parameter backups and diagnostic access can be handled from standard laptops. Functional safety is addressed through the integrated Safe Torque Off channel, which removes drive power through a 9-pin D-Sub interface and verifies interruption with a 24 V / 3 mA sense circuit. The unit also includes 100Base-TX RJ-45 connectors and relay contacts rated at 24 VDC and 1 A for low-voltage signaling.
