Note 1. After resolving the source of trouble, cool the equipment for approximately 30 minutes.
2. 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)
Refer to the following table for the specified servo motors. The stop method for other than the specified
servo motors is DB.
For MR-JE_A, setting [Pr. PF09] to "(_ _ _ 3)" enables the electronic dynamic brake.
SD: Forced stop deceleration
3. 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].
4. In some controller communication status, the alarm factor may not be removed.
