Note 1. Leave for about 30 minutes of cooling time after removing the cause of occurrence.
2. In some controller communication status, the alarm factor may not be removed.
3. The following shows three stop methods of DB, EDB, and SD.
DB: Dynamic brake stop (For a servo amplifier without the dynamic brake, the servo motor coasts.)
EDB: Electronic dynamic brake stop (available with specified servo motors)
SD: Forced stop deceleration
4. This is applicable when [Pr. PA04] is set to the initial value. The stop method of SD can be changed to DB using
[Pr. PA04].
