E.OPT
Option fault
Mitsubishi Electric · FR E700
What does E.OPT mean?
This fault appears when a communication option is connected, but the password lock (Pr. 296 = "0 or 100") is preventing its proper function. This issue specifically relates to the security settings for optional communication modules. Resolving it ensures the communication option can operate correctly.
Repair Steps
- 1
Verify the Pr. 296 setting; if a password lock is desired, ensure Pr. 296 is set to a value other than "0" or "100" when installing communication options.
