Industry insightPublished: VFD Fault Codes Decoded: OC, OV, OL and What They Really MeanNearly every drive trip belongs to one of four families: overcurrent, overvoltage, overload or overtemperature. Diagnosing them in the right order turns an alarming red display into a five-minute check with a meter.
Industry insightPublished: Sizing a VFD for a Screw Air CompressorAir compressors are constant-torque loads but they are not ordinary ones: unloaded running, oil temperature and a narrow usable speed band all change the calculation. Here is how to size the drive and avoid the classic resonance problem.
Industry insightPublished: VFD Panel Cooling: Derating Rules and Ventilation DesignEvery drive is rated at a reference ambient temperature, usually 40 degrees Celsius. Above that, the continuous output current must come down. This note covers the derating curve, altitude derating and how to size panel ventilation without importing dust.
Industry insightPublished: Solar Pump Inverter or Standard VFD for Off-Grid Irrigation?A solar pump inverter and a standard VFD both control a motor, but only one is designed to harvest a varying DC source, protect a pump against dry running and survive a remote site. Here is how to choose.
