Product Description:
The Bosch Rexroth Indramat CDB01.1C-PB-EN2-EN2-NNN-NNN-S2-S-NN-FW is a modular controller card installed inside IndraDrive drive assemblies within the CDB Control Units series. Acting as the processing core, it coordinates motion axes, manages encoder feedback, and exchanges real-time data with higher-level PLCs over a PROFIBUS network. By integrating twin EnDat-compatible feedback channels and Safe Motion logic, the card supports safety-oriented positioning in packaging machinery, pick-and-place cells, and material-handling robots. Its role inside the drive is to handle motion control tasks and feedback evaluation without requiring a separate external control card for each axis.
The control card draws a base idle power of 9 W, minimizing thermal load inside enclosed cabinets. Its dedicated PROFIBUS interface communicates at 12 MBaud, delivering cyclic setpoint and diagnostic telegrams without overloading the system bus. Each EN2 measurement channel terminates the encoder line with 35 ohms of resistance to preserve signal quality at high frequencies. For analog sinusoidal feedback, the hardware specifies a cutoff of 500 kHz, while digital square-wave inputs are accepted up to 1000 kHz. These limits help the control unit process encoder signals accurately during high-speed motion, and the card supports EnDat 2.1, 1 Vpp, and 5 V TTL feedback formats for broad sensor compatibility.
Each EN2 channel is powered from a controlled rail that delivers 350 mA at 5.0 V, providing sufficient current for typical optical encoders without exceeding the module’s own dissipation limits. The separate PROFIBUS plug-in consumes 2 W, so the total board load stays within the stated power envelope for multi-axis drives. Two probe inputs enable time-critical position latching, and a relay rated at 24 VDC, 1 A can forward drive status to external interlock circuits. Safe Motion monitoring, an RS-232 service port that operates up to 115 kBaud, and the shared encoder logic complete the unit’s real-time control and diagnostic functions.
