Product Description:

The CDB01.1C-PB-EN2-EN2-NNN-NNN-S1-S-NN-FW is a plug-in control section manufactured by Bosch Rexroth Indramat as part of the CDB Control Units series. It mounts on an IndraDrive power module and provides the computing, communication, and safety functions needed for closed-loop motor control in automated machinery. By accepting fieldbus commands, converting them into real-time current setpoints, and monitoring feedback from incremental or absolute encoders, the board enables precise positioning and coordinated motion inside multi-axis production cells. It also serves as the interface between the drive power stage, the feedback channels, and the higher-level machine controller.

The analog interface accommodates an input span of ±10 V, letting PLCs feed velocity or torque references without additional scaling hardware. Two converter stages generate an output signal of 5 V / 1 mA per channel, which can drive external indicators or pass conditioned signals to supervisory controls. For networked installations the board communicates as a slave over PROFIBUS, while a legacy maintenance port based on RS232 supports parameter access from a laptop. The card measures 322.6 × 49.5 × 103 mm, so it fits into slim drive stacks, and a single-line display on the front panel provides direct access to operating parameters.

The control logic can sequence 2 controlled axes and processes position data through a multifunctional encoder port that accepts EnDat 2.1 / 1 Vpp / TTL formats, allowing mixed feedback types on the same unit. Integrated safety is handled through a D-Sub, 9-pole connector, and its outputs can switch up to 24 V / 0.5 A to remove torque in emergency-stop circuits. An internal relay with one normally open contact provides an additional hardware interlock for external safety chains. This arrangement keeps the Safety Technology I/O function independent of the communication bus and reduces wiring for axis-disable functions.
