Internal circuit fault

What does E.13 mean?

This code, along with E.5 to E.7, indicates a specific internal circuit fault within the FR-A800/A800 Plus Series drive. It implies a hardware or firmware issue that causes an unexpected internal state, leading to a protective stop.

• Component failure on one of the drive's internal circuit boards.
• Transient electrical disturbance causing unexpected logic operation.
• Firmware execution error or corruption.
• Unstable power supply to the internal control electronics.
• Excessive operating temperature affecting sensitive internal components.

Click steps to track your progress.

1. 1

   Execute a full power cycle of the FR-A800/A800 Plus Series drive by disconnecting both main and control power for at least 5 minutes.

2. 2

   Check the input power supply for stability and proper voltage levels, and verify the drive's grounding.

3. 3

   Ensure the cooling system of the drive is functioning correctly and that ambient temperatures are within specified limits.

4. 4

   Visually inspect the drive's internal circuit boards for any signs of damage, burn marks, or loose connections.

5. 5

   If the fault persists after these steps, it signifies an internal hardware failure, and the drive unit will likely require replacement.
