Learn the step-by-step measurement sequence for assessing output factors of a variable frequency drive when troubleshooting electrical signals

Learn the 5 steps to measuring output voltage when troubleshooting VFD problems

When troubleshooting the electrical signals within a motor/drive system, think in terms of input vs. output. A variable frequency drive (VFD) transforms the input mains of constant voltage and frequency into a voltage and frequency range that can be varied to control motor torque. Troubleshooting at the input starts with testing power and supply.
