The Z-axis is unique because it must constantly fight gravity. Common root causes include: Diagnose a Fanuc High Current Alarm in 10-Steps
Check the cooling fans on the back of the servo amplifier. If they fail, the drive will overheat and trigger a 414 alarm. To help you narrow this down, could you tell me: fanuc 414 servo alarm z axis detect error
: Sometimes a loose connection on the amplifier's internal logic board (the gray faceplate board) can cause intermittent detection errors for the 200 and 204 parameters? The Z-axis is unique because it must constantly
Since this was a multi-axis drive, he knew the Z-axis was the one drawing way too much "juice". 2. Hunting for the Short fanuc 414 servo alarm z axis detect error
Because the Z-axis is vertical, mechanical issues manifest differently here than on horizontal axes.
