Fanuc 414 Servo Alarm Z Axis Detect Error !new! Here

In 8 out of 10 cases, Alarm 414 (Z-axis detect error) is a worn encoder cable or intermittent connector . Always check the simple, physical connections before ordering expensive parts.

A common culprit is a defective servo amplifier module , specifically a burned-out IGBT or internal circuit damage. fanuc 414 servo alarm z axis detect error

The on the Z-axis is a high-current detection error within the digital servo system. It signifies that the CNC control has detected abnormal current flow or a hardware fault related to the Z-axis servo amplifier, motor, or cabling. Because the Z-axis often carries the weight of a spindle or heavy tooling, this error can also be triggered by mechanical binding or counterweight failure. Understanding the 414 Alarm Signal In 8 out of 10 cases, Alarm 414

Indicates an A/D converter (current detection) error. Common Causes & Solutions The on the Z-axis is a high-current detection

When this alarm occurs, the CNC screen displays "414 SERVO ALARM: Z AXIS DETECT ERROR". However, the machine's electrical cabinet provides the specific hardware status:
