FANUC 18TA control
Series C amplifiers (one dual, one single)
Okuma-Howa ACT20 lathe
I have a turret indexing problem that has me dead in the water. I continually get the 414 alarm which turns out to be the HCA.
I have spent weeks on this and ruled out hydraulic problems, unclamp limit switch problems, bearing issues within the turret, cabling issues from the amplifier output to the servo motor. Replaced the alarm module in the servo amp. No joy.
The only thing I can think left to do is check the servo amp tuning parameters and be sure the max current setting (if one exists) is set properly.
The control on this machine recently smoked a power supply board. By the time it got replaced the parameter memory was corrupted. I can't help but think a parameter got missed with the reload. But, the turret was acting up before this happened. Once the power was applied to the control for about an hour everything was fine. Now it's a solid no-go. Do a manual index - bam! E-stop condition. Call a tool through MDI - bam! E-stop condition.
Any help/guidance is much appreciated.
EDIT: I have checked the power semiconductors on the amplifier and even swapped amps. Problem moved to the other amp.
