Option Fault

What does E.OPT mean?

This fault occurs when an incompatible or non-existent regenerative option is selected in parameter E300 (Pr.30), such as a high-efficiency converter or power supply regeneration common converter, but no such option is connected or detected by the FR-A800 inverter. The inverter will trip to prevent incorrect operation.

• Parameter E300 (Pr.30) (Regenerative function selection) is incorrectly set to '2' (high efficiency converter or power supply regeneration common converter connection) without the corresponding hardware connected.
• Faulty or improperly connected regenerative option unit.
• Internal FR-A800 inverter hardware issue related to option detection.

Click steps to track your progress.

1. 1

   Verify parameter E300 (Pr.30) (Regenerative function selection) matches the installed hardware. If no external regenerative option is connected, set E300 (Pr.30) to '0' (built-in brake).

2. 2

   If a regenerative option is installed, inspect its wiring and connections to the FR-A800 inverter for looseness or damage.

3. 3

   Consult the manual for the specific regenerative option for its diagnostic indicators and troubleshooting.

4. 4

   If the issue persists after verifying settings and connections, consider replacing the regenerative option unit or the inverter if the fault points to internal issues.
