Viceroy Bowl Lathe
Hi All,
I have recently purchased an old Viceroy Bowl Lathe the motor is 3phase, so I have installed a VFD - which works fine; however once I start to turn the speed drops off to a stand still until I remove the chisel. Any thoughts?
Regards

Possibly the max torque or max power or max current setting are set too low or don't match the motor. There should be some settings to match the VSD to the motor name plate, then set the others to around 120 to 150%. If this doesn't fix it, it starts to get complicated...
The world is a comedy to those that think, a tragedy to those that feel.

Thanks Yowie,
tried playing with a few of the settings with no luck, the VSD allows a auto motor tune, which I did; but now going out on Over current, tried to reset the factory settings but no luck so far, I've sent an email to the manufacture to get some help
thanks again

Look in the manual to see if there is a setting for CT (Constant Torque).
This article helps explain some of the variables.

Hi
Have you changed the motor to delta connection changing it to 240V
Cheers
Can you put a pic of the inverter or let us know what brand it is?
