How Quad Plus Can Help You
We inspect a Variable Frequency Drive (VFD) unit for defects by using a complex series of tests and industrial application simulations. If we find any defects or there are any VFD unit specifications that are out of the manufacturer specified tolerance range, we investigate and repair them. We then retest for function and if everything passes our comprehensive test procedures we then thoroughly clean the drive and get it back in service. We generally test a Variable Frequency Drive Unit by connecting it to a power matched size motor and dynamically loading the motor to make sure the Drive Unit can handle the current and torque requirements specified by the VFD unit’s nameplate.
