Product Description:

The CDB01.1C-SE-EN1-EN1-NNN-NNN-S1-S-NN-FW is a compact control section produced by Bosch Rexroth Indramat for the CDB Control Units series. Installed inside IndraDrive modular systems, the unit coordinates two servo axes and provides the link between motion commands and power modules. By handling fieldbus communication, feedback decoding, and local I/O, it serves as the central control section that synchronizes motors, sensors, and actuators within automated assembly lines, packaging machinery, and similar industrial equipment. It mounts on the front of a drive stack and relies on plug-in connectors so installation remains straightforward.

The analog output stage refreshes process values every 10 µs, enabled by an 8-bit converter that matches typical drive command resolution requirements. At a nominal level of 5 V / 1 mA, the channel can feed velocity or torque references to external modules, with increments of 19.5 mV per step allowing fine adjustment. Control data are exchanged with the drive via SERCOS II, providing deterministic timing for multi-axis interpolation. For onboard logic and sensor chains, the digital I/O rail supplies 1.1 A, and the high-side outputs can switch inductive loads without requiring external low-side drivers. Two resolver and HSF ports accept position feedback directly from the motors, eliminating the need for intermediate converters.

The control card supervises 2 axes so coordinated motion can be handled without an additional master. Each high-side driver can deliver 500 mA, which is adequate for solenoid valves or signal lamps mounted near the drive cabinet. Safety Technology I/O is integrated, and its circuit is powered from DC 24 V through a D-Sub 9 female connector. Input channels operate at 24 V and draw 3 mA, while the dedicated safety outputs can disconnect actuators with a 24 V, 0.5 A rating. A service port based on RS232 supports parameter backup and diagnostic access, and the direct motor feedback interfaces help keep the control layout compact.
