Hi All,
Hoping for some help and pointers here if at all possible. My 2x72 belt grinder has stopped working. I tried to use it today and it will not start. I have a YL620 VFD wired up to a potentiometer and until today everything seemed to be working great. Today the main display on the VFD is flashing and FOR light is on. When I turn the potentiometer (remote) the display shows increasing frequency but the motor on the grinder does not start at all. Not sure where to start looking. The ambient temperature today is low and the grinder is in my garage - could it be the low ambient temperature that is the problem? I am new to VFD's.
Thanks.
