Hi Guys,
I have a problem on a Doosan Lynx and am after some help as there are no alarms on the control or the spindle amplifier.
The controller is Fanuc Oi-TC and the machine has a bar feeder attached.
The machine is all referenced up, axes and turret move without any issues.
When I try and run the spindle (S1, not duel spindle) in MDI, at say 1000RPM, the spindle accelerates quickly to around 100 RPM and then decelerates quickly to 3 RPM and continues.
The same happens when I try and turn the spindle in manual mode.
When rotating the spindle by hand I can see the RPM change on the screen.
Checked the BZi speed sensor for runout and gap setting. All looks OK. If I disconnect this from the spindle Amp I do get an alarm.
I am at a loss where to look next as there are no alarms.
Hope somebody can help or has has similar experience before.
