Product Description:

The CDB01.1C-PB-ENS-ENS-EN2-NNN-L2-S-NN-FW is a modular control unit produced by Bosch Rexroth Indramat for the CDB Control Units series. Mounted on an IndraDrive power section, the board supervises drive behavior, processes encoder feedback, and forwards status data to the cell controller. Within packaging, printing, or material-handling equipment, it provides the logic that coordinates drives and permits a safety-related stop when commanded by the machine sequence. As a drive-embedded computer, it acts as the local interface between motion hardware and higher-level PLC networks, helping keep cycle times consistent while reducing wiring complexity.

It draws control power from a DC 24 V bus. At startup, the module can momentarily require up to 6 A for about 60 ms, so cabinet fuses and conductors must be sized for this peak. Once the capacitors are charged, power demand stabilizes at 9 W. A capability of 2 interpolated axes lets the card govern two servo channels. PROFIBUS handles cyclic setpoint exchange and diagnostics, so the unit integrates with PLC platforms without protocol converters. The standard operator panel offers parameter access and LED status indication. Low-voltage terminals together provide 1000 mA for sensors, encoders, and relay coils connected to the drive.

For analog monitoring, the card supplies two voltage outputs. Each output can source up to 1 mA at a reference level of 5 V with a resolution of 19.5 mV/inc, allowing linear representation of torque, speed, or position signals on external meters. Digital signaling capacity reaches 500 mA across the EnS and general-purpose outputs, while a separate EN2 port offers 350 mA for encoder excitation. A relay rated at 24 VDC and 1 A can energize brakes or alarm beacons. Functional safety is handled by the integrated Safe Torque Off channel, which disables gate firing to the power stage so mechanical motion ceases without removing the main supply.
