Product Description:
The 80VD100PD.C144-01 is an inverter module produced by B & R Automation within the 80VD Inverter Modules series. It serves as the motor power stage in multi-axis machinery, taking energy from a shared DC bus and generating a variable AC waveform for precise motor speed control. The module is intended for industrial automation tasks such as coordinated motion on packaging lines, feeders, and indexing tables where tight electrical drive regulation is required.
The power section is rated for a continuous output of 1.31 kW, allowing the module to sustain mechanical work without thermal derating. To deliver this power, the phase bridge can provide a nominal current of 8 A RMS and 11.3 A peak, matching servo or induction motors. Energy storage on the DC link is supplied by a capacitor bank totaling 940 µF; this capacitance smooths regenerated energy and limits voltage ripple during dynamic load changes. Maximum synthesized output frequency reaches 598 Hz, so high-speed spindles or low-pole servomotors can be driven above line frequency. Controller operations run at 20 kHz, while an inrush limiter keeps startup current below 10 A and a brake transistor can dissipate 1 A when dynamic braking is commanded. The embedded CPU consumes only 8 W, leaving headroom for the output stage.
Control electronics draw power from a field supply of 24 VDC ±25%, and the same rail feeds the configurable digital output rated at 1 A for external relays. Gate pulses reach the IGBTs at a switching rate of 5 kHz, a value chosen to reduce audible motor noise while maintaining good efficiency. Feedback handling is integrated: a counter with 32-bit resolution tracks encoder position at up to 200 kHz, and the module can source 350 mA at 5 VDC for encoder electronics. Motor terminals may be routed up to 25 m without additional filters, and the housing carries an IP20 rating for installation inside enclosed electrical panels.
