I've seen this message from my VFD's while setting up dynamic braking where the motor back EMF from motor deceleration (motor becomes more like a generator) back drives the VFD's DC bus beyond the bus maximum voltage. Fitting an appropriate braking resistor or limiting the motor's deceleration usually fixes this. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity and more.
