Product Description:

The CDB01.1C-ET-EN1-EN1-NNN-NNN-S2-S-NN-FW is a plug-in control unit built by Bosch Rexroth Indramat for the CDB Control Units series. Installed in IndraDrive power sections, it acts as the command layer that interprets feedback, issues switching signals, and links motion axes with higher-level programmable controllers. By coordinating speed, torque, and position loops, the module supports automated packaging, handling, and machining cells that depend on precise, repeatable motion.

On the analog side, the board offers two output channels that generate reference voltages. Each channel is limited to 5 V, 1 mA, so downstream circuitry must observe this low-power budget. Its fieldbus connector exposes Multi-Ethernet capability, allowing the same hardware to run EtherNet/IP, PROFINET, or EtherCAT. Local interaction is handled through a Single-line display that shows status words and parameter numbers. Four transistor outputs share a common supply and can switch up to 500 mA for contactors or indicator lamps. Position feedback is accepted through 2 x EN1 encoder interfaces, and resolver or high-speed sin-cos signals provide high-resolution data to the control loop. Two probe inputs capture latch positions used for homing or print-mark detection.

Power for the sensing transducers is delivered at 8 V, protecting delicate encoder electronics. Real-time networking to an external switch is handled through the shielded Ethernet socket specified as RJ-45, 8-pin. A ready relay rated at DC 24 V, 1 A reports drive enable to safety PLCs, and the brake circuit plus emergency stop chain connect through a D-Sub 9-pin female safety plug. Motion monitoring is implemented with Safe Motion S2, which provides STO and SS1 functions without extra hardware. For diagnostic traces or serial communication, a full-duplex RS232 serial port remains available.
