Product Description:

The CDB01.1C-PB-EN1-EN1-NNN-NNN-S1-S-NN-FW is a drive control unit produced by Bosch Rexroth Indramat and supplied within the CDB Control Units series. When inserted into an IndraDrive power module, it serves as the command core that translates fieldbus references into tightly regulated motor currents for two mechanical axes. The card supports motion sequencing, local diagnostics, and integrated Safety Technology I/O, enabling machinery such as palletizers, pick-and-place gantries, and web converters to achieve coordinated positioning without a separate PLC. Its front edge carries a single-line display and push keys so active parameters can be inspected on site.

For time-critical control loops, the unit refreshes phase currents every 125 µs, a rate that helps keep torque ripple low even on rapidly reversing loads. The internal firmware manages 2 axes and pairs each channel with dual resolver/HSF encoder interfaces, allowing accurate feedback during high-speed operation. Command values reach the controller over the PROFIBUS-DP port, while fine analog references can be issued through two outputs that swing to 5 V at up to 1 mA. An additional pair of analog outputs is present, giving four-quadrant torque or speed readback when detailed process monitoring is required.

Discrete interfacing is handled by eight transistor outputs that can source 500 mA in total and by a relay rated at DC 24 V, 1 A for switching contactors or brakes. Sensor supplies are available, including an encoder line that delivers 8 V to resolver electronics. Application data can be stored on a MultiMediaCard for local backup, and a built-in RS232 service port allows parameter uploads when the fieldbus is unavailable. Dedicated S1 terminals provide 24 V inputs at 3 mA and safeguarded 0.5 A outputs that interact with the unit’s Safety Technology I/O to enforce controlled stops.
