Product Description:

The CDB01.1C-PB-EN1-EN2-NNN-NNN-NN-S-NN-FW is a plug-in motion control card manufactured by Bosch Rexroth Indramat for the CDB Control Units series. Installed on an IndraDrive base, the board forms the interface between higher-level automation networks and the power electronics that drive servo motors. It interprets fieldbus commands, generates interpolated trajectories, and supervises feedback devices so that machine axes hold commanded positions with millisecond accuracy. Within an industrial cell, the unit centralizes axis logic and communication, reducing panel space and wiring compared with discrete drive controllers.

At the drive level, the unit supervises 2 axes and draws a configured power budget of 23 W from the power section. During power-up, an inrush of 6 A is tolerated before consumption settles to its normal level. Motion feedback is accepted on Encoder Interface 1, which supports resolver or HSF devices, and on Encoder Interface 2, which can read EnDat 2.1, 1 Vpp, or 5 V TTL signals, allowing mixed sensor types to share the same controller. For fieldbus exchange, the integrated PROFIBUS DP port transmits cyclic and acyclic frames at 12 MBaud. Time-critical command outputs can be generated with a maximum pulse width of 60 ms, while the I/O rail can deliver current for external sensors and actuators.

Two buffered DAC channels provide 2 analog outputs for velocity or torque references. The first feedback supply delivers 250 mA at 8 V to power HSF transducers, with an 18.2 Vpp resolver carrier oscillating at 4 kHz for rotor position tracking. The second encoder port offers 5.0 V at 350 mA to energize EnDat or TTL sensors. For point-to-point service access, a built-in RS-232 link allows parameter backup and diagnostic capture without occupying the fieldbus. Because both channels share identical timing, the controller can maintain synchronized interpolation whenever coordinated motion is required.
