| Code | Message | Description & Solution | | :--- | :--- | :--- | | | VRDY OFF | The servo drive unit is not ready. Check for power supply issues or emergency stop activation. | | SV0403 | CARD SLOT CHANGE ERROR | Related to the servo amplifier setup. Consult maintenance. | | SV0404 | VRDY ON | The servo is ready when it shouldn't be. Usually a contactor sticking or drive fault. | | SV0410 | Servo Alarm: n-th Axis | General servo error. Often requires checking the servo motor cables or encoder. | | SV0411 | Motion Error | The axis moved more than the allowed tolerance. Check for debris on the slideway or mechanical interference. | | SV0436 | Soft Thermal (OVC) | The motor is overworking (overcurrent). Check for axis binding, lack of lubrication, or heavy cutting loads. | | SV0447 | Current Offset Error | A parameter error related to current detection. Requires parameter reload or servo drive replacement. |
These alarms are generated by the machine's internal logic (PLC) and often relate to safety or mechanical interlocks. mori seiki alarm list
Understanding Mori Seiki alarm codes is essential for keeping your CNC machines running smoothly. Alarms typically fall into two categories: (from the Fanuc or Mitsubishi control) and Machine Alarms (often prefixed with EX , specific to Mori Seiki's PLC). 🛠️ Common Mori Seiki "EX" Alarms | Code | Message | Description & Solution
Understanding the alarm list on a Mori Seiki CNC machine is critical for maintaining uptime and ensuring precision. Because Mori Seiki machines—spanning legacy models to modern DMG Mori systems—utilize various controls like Fanuc, Mitsubishi, and Siemens, identifying the correct error code category is the first step in troubleshooting.
