Product Description:

The 80VD100PD.C033-1 inverter module is produced by B&R Automation as part of the 80VD Inverter Modules series. It converts energy from a shared DC link into controlled phase currents so that connected motors can follow precise speed or torque commands inside industrial automation cells. Two dedicated encoder inputs support closed-loop operation, allowing the drive to process position feedback without delegating that task to a higher-level controller.

The power section relies on an auxiliary supply voltage of 24 VDC ±25% for the control electronics, and its output stage supplies a continuous motor line current of 8 A. Under rated conditions, the unit registers 1.31 kW of continuous power consumption, while its internal controller frequency of 20 kHz provides frequent modulation updates for tight current regulation. A capacitance of 940 µF on the DC bus buffers energy against load transients. Feedback hardware is powered through a regulated encoder rail of 5 V ±5%; this rail can deliver 250 mA and is intended for SSI absolute encoders. The CPU requires 8 W during processing cycles and only 0.5 W when the drive is idle, minimizing heat buildup in standby states.

At startup, an inrush current of 10 A charges the capacitor bank, after which the module can withstand an internal peak current of 30 A. For motion surges, the phase terminals permit a peak current of up to 15 A, provided that the motor cable length remains within 25 m. The switches commutate at a nominal frequency of 5 kHz, balancing switching losses with moderate acoustic noise. Conductor capacity, fuse protection, and cooling provisions must account for these operating limits to keep the drive within safe thermal and electromagnetic margins.
