Dear all

Hope someone can help.

My Emco Turn 55 had not been used for over 5 years. I finally got round to starting it. When executing a cutting program, the XZ and toolchanger all worked as programmed but the lathe will give a high pitch whine that last for maybe 1-2 seconds or so and then an error message pops up to say "no main spindle speed". The spindle did not move even a bit.

I took out the back panel to check on the Lenze 8200 Inverter Drive. When I switch on the PC Turn, immediately the Lenze Inverter Green LED started blinking and continue to blink nonstop. It will go solid green when it tried to execute the M3 code and whine. Once the whine stopped, it goes back to blinking.

I downloaded Lenze manual and it said that it could be "Motor parameter identification being executed" or it could be "Controller Inhibited". I am not sure what either of that means. Could it be that the spindle motor parameter has to be reentered into the Lenze because the memory for the spindle motor was lost?

Any help is greatly appreciated.
