I was wondering if there is any way to tell if the capcitors in a VFD are failing. I have an old(1994) Omron vfd on my surface grinder, and as soon as you shut off the power the drive shuts down. But on my mill, the drive stays on for at least a minute(without the motor running). The vfd on the mill is an Allen Bradley, no more than 2 years old, less than 20 hours run time.
I let both of the drives sit powered up, but not running the motor, for at least 8 hours.
Is there any way to check the condition of the capacitors if that isn't a indication of there condition?
Thanks
