Okuma Crown OSP700L

[valdi3]

Hi guys,
We are working on Okuma Crown 1998 OSP 700L and turret keeps stopping (lock) ones a while with alarm 1762-A Servo Turret Overload. Looks like turret doesn't do all turn to the called station and alarm pop out. Then we have to on manual mode turn turret to the next station. We can't find the reason or fix it.
Is anyone had problem like that?

Please help!

Could be a number of things.
Turret encoder comes to mind.
Prox switches.
Dirt.
Misalignment.
Corrosion.
Loose cables.
