Product Description:

The CDB01.1C-S3-ENS-EN2-NNN-NNN-L2-S-NN-FW belongs to the CDB Control Units series from Bosch Rexroth Indramat. This control unit is installed inside Rexroth drive packages to process feedback, manage power-stage commands, and coordinate multi-axis motion in automated machinery. By combining axis control, real-time fieldbus communication, and integrated safety, the device supports servo tuning and supervisory tasks in packaging, printing, and material-handling lines.

The module supervises 2 axes and exchanges cyclic data over the real-time network protocol SERCOS III. Physical connection to this bus is made through a rugged RJ-45, 8-pin socket that follows the IEEE 802.3 Ethernet layer, so standard industrial cables can be used. A secondary RS232 port supports point-to-point service access and diagnostics. Position feedback is accepted on Encoder 1 through a D-Sub 15-pin female connector, and this channel delivers 11.6 V at up to 500 mA to power optical or magnetic encoders. A separate Encoder 2 supply delivers 5 V at 350 mA and allows resistive loads down to 35 ohms, allowing TTL or SinCos sensors on the second axis without external regulators.

The control unit provides an analog monitor output that sources 1 mA or sinks it into a 5 V reference to display internal values on test equipment. The same channel can be configured as a command output when the associated drive expects an analog setpoint. Digital safety is addressed with the hardware-enforced Safe Torque Off function that removes gate signals to the power stage within one processing cycle. A relay rated for 1 A at DC 24 V can flag drive-ready status to higher-level PLCs, and its floating contact isolates field voltages from the logic backplane. Combined with the analog capabilities, the 5 V auxiliary source and the 11.6 V encoder rail provide flexible signal levels while keeping cabinet wiring compact.
