Verify the output of the 24VDC power supply units in the cabinet. Fluctuating or low voltage can trigger intermittent 7115 errors. Inspect Contactors: Manually check and test the high/low gear or winding contactors
An essay on the focuses on its role as a critical indicator of servo system failure . In CNC operations, this alarm typically signifies an "Excess Error" or "Servo Overload," where the machine's physical movement deviates beyond its programmed tolerance. The Mechanics of the 7115 Alarm
: Ensure the auxiliary contacts on the switching contactors are sending the correct confirmation signals back to the CNC. A missing feedback signal will trigger the 7115 alarm. Test Wiring
: This is the most frequent culprit. If the 24VDC power supply (often manufactured by brands like Izumi) that powers the relay and contactor coils fails, the switching circuit cannot operate.
If this "handshake" fails, the 7115 alarm triggers to prevent mechanical damage or electrical surges that could occur if the machine tried to accelerate while stuck between ranges. Common Root Causes Electrical Power Loss: A common culprit is the failure of the 24VDC power supplies
