Powermatic 4224 spindle rotation in reverse order???

HELP !!! I'm new to woodturning. After a few lessons and attending a woodturning symposium I got hooked. One of my lessons was on a Powermatic

4224. A great tool compared to the old 11" Rockwell that I have been using, so I ordered the Powermatic 4224. I finally received my brand new lathe, but to my dismay there were two problems.

  1. When I turn on the lathe, the spindle of the lathe turns counter clockwise, but the Inverter's LED Status Display shows the lathe's spindle turning in a reverse status. When I switch the Fwd/Rev Switch into the opposite direction, the spindle of the lathe turns clockwise, but the Inverter's LED Status Display shows the lathe's spindle turning in a forward status.

I think the spindle rotation direction is faulty. When the spindle is in a counter-clock rotation the Inverter LED Status Display should show the lathe is in a forward Status. Would you consider this an accurate statement? I don't know how serious a problem this could be, but considering the cost of this lathe I would like to have it working correctly.

  1. The Speed Indicator Sensor that displays the RPM on the headstock was loose, resulting in a zero LED reading on the headstock.

Through trail and error I adjusted the sensor to a clearance of about 1/16th of an inch. I now get an RPM reading on the LED, but it would be nice to know the correct gage clearance.

I have been told by the Technician that I can use the lathe in this conditions, but I'm anxious to correct these problems. I'm patiently awaiting a Technician to come and look at my lathe. As this is my 4th week waiting, I would greatly appreciate any suggestions from you to help me resolve these problems.

Thank you very much, Alex

That's the problem with those off brand machines. Ya shudda stuck with Harbor Fright.

You will have a 3 Phase Motor driven from the Inverter with these Motors you can change the Rotation by changing any two wires over.

Should be worth a try, you cannot do any damage just swap two wires round either at the Inverter or at the Motor.

^^^^^^^^^^^^^^^^^^^ No. Switch any two (of the three) motor wires.

There will be a fourth motor wire -- the ground. Leave it alone but, as Leo says, switch any two of the three live wires either in the motor electrical box or at the vfd.
