Product Description:

The 80VD100PD.C022-01 inverter module from B&R Automation belongs to the 80VD Inverter Modules series. It is an AC drive component that receives a DC bus from the parent supply and generates pulse-width-modulated outputs for servo motors. Within an automation cell, the module closes the current loop, supplies phase-aligned voltage to up to two motors, and communicates with the machine controller through its integrated Powerlink interface.

The module delivers a continuous phase current of 8 A RMS, sufficient for mid-frame servo axes used in packaging or material handling. For brief acceleration commands, each motor can draw up to 15 A without derating, while the overall module withstands a combined surge of 30 A peak. Output frequency is adjustable up to 598 Hz, so high-speed permanent-magnet motors remain within vector control range. Current commands are updated by a torque controller that runs at 20 kHz, and the IGBT bridge itself is switched at a nominal carrier of 5 kHz, balancing semiconductor loss and acoustic noise. Two digital inputs are available for local enable or fault reset signals, and separate resolver channels capture rotor position for each connected motor.

To stabilize the intermediate circuit, the module integrates 940 µF of film capacitance that smooths regenerated energy during deceleration and limits bus ripple. Control electronics draw only 8 W, which simplifies cabinet thermal calculations and allows operation near the controller side of the DIN rail. The resolver interface samples position with 14 bits/rev angular resolution at 10 kHz excitation, giving the drive adequate accuracy for synchronous servo loops without external encoders. An IP20 housing permits installation inside a closed electrical cabinet where touch protection is required but no liquid ingress is expected. Motor leads can be routed up to 25 m, and two female RJ45 Powerlink ports provide network access for cycle times below a millisecond.
