How to troubleshoot servo motor positioning errors on LNS Industrial Equipment?
In this situation, the motor increases the pushing torque to a defined limit. Press the STOP button on the remote control to reset the alarm. Check for any mechanical obstructions preventing the bar stock from feeding out. Verify that the bar stock diameter matches the value entered in the remote control under "applications". Ensure the alignment between the lathe and the bar feeder, which may shift if the machines aren't anchored. If the problem continues, contact LNS.
What does 'Amplifier battery low!' mean on my LNS Industrial Equipment, and how do I fix it?
Replace the battery as soon as possible.
What should I do if my LNS Industrial Equipment displays a 'Servo drive alarm!'?
If this problem arises, find the alarm number displayed on the servo amplifier and refer to the Mitsubishi® servo amplifier alarm list.
What causes a 'Servo amplifier/PLC communication fault!' on LNS Industrial Equipment?
This issue can occur if the sent data doesn't match the received data, if the servo amplifier doesn't respond within 10 seconds, or if PLC and servo amplifier parameters don't match during the bar feeder's startup. Verify the PLC/servo amplifier connection and the PLC power supply (24V DC), as power variations can affect PLC efficiency. If the problem persists, contact LNS.
What does 'Bar stock loading error!' mean on my LNS QL Servo 80 S2, and how can I resolve it?
Load new material onto the magazine.
What should I do if the lathe does not resume its production cycle with LNS QL Servo 80 S2 Industrial Equipment?
Press the STOP button on the remote control to reset the alarm. Restart the automatic cycle on bar feeder and lathe.
How to fix the 'Emergency stop line open!' error on my LNS QL Servo 80 S2 Industrial Equipment?
The problem is usually triggered by an open in the safety circuit. To resolve this, check the PLC connection, inspect the wiring based on the electrical diagram, and verify the state of the emergency buttons on both the bar feeder and the lathe. Alternatively, you can press the STOP button on the remote control to reset the alarm.
