E.16 to E.20
User-Defined PLC Function Error
Mitsubishi · FR-E800 Variable Frequency Drive
What does E.16 to E.20 mean?
The inverter output is shut off because a user-defined protective function, configured via the PLC function, has been activated. This occurs when a value between "16" and "20" is written to the special register SD1214 while the PLC function is enabled (Pr.414 is not "0"). It signifies a condition that the user's PLC program has flagged as a fault.

In the PLC program, modify the logic to ensure a value other than "16" through "20" is written to the special register SD1214, or address the condition that causes this range to be written.
