Hey there! I know that sinking feeling when you see that F70 overcurrent error pop up during peak production - been there myself. Here's my go-to emergency protocol to get you back online fast:

🚨 **First 5 Minutes - Safety & Quick Assessment**

• Immediately stop the line and lock out the power

• Check for obvious mechanical binding - can you turn the motor shaft by hand?

• Look for burnt smells, smoke, or visible damage

• Note the exact error code and any recent changes

⚡ **Next 10 Minutes - Electrical Checks**

• Disconnect motor cables and check for short circuits between phases

• Verify power supply voltages are within spec

• Inspect cable connections for looseness or corrosion

• Check if the motor overheated - let it cool if needed

🔄 **Final 15 Minutes - Reset & Test**

• Power cycle the entire servo system

• Clear the alarm and attempt a slow jog test

• If it runs, gradually increase speed while monitoring current

• If error persists, swap with a known good motor temporarily

The key is systematic elimination - start with the simplest causes first. Most F70 errors are mechanical binding or loose connections that you can fix quickly. If it's a deeper electrical issue, at least you'll know exactly what to tell the production manager about the extended downtime!
