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 alarm can be canceled by setting as follows:
For the fully closed loop control: set [Pr. PE03] to "1 _ _ _".
When a linear servo motor or a direct drive motor is used: set [Pr. PL04] to "1 _ _ _".
4. The following shows three stop methods of DB, EDB, and SD.
DB: Stops with dynamic brake. (Coasts for the servo amplifier without dynamic brake.)
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 will be DB.
Series Servo motor
HG-KR HG-KR053/HG-KR13/HG-KR23/HG-KR43
HG-MR HG-MR053/HG-MR13/HG-MR23/HG-MR43
HG-SR HG-SR51/HG-SR52
SD: Forced stop deceleration
5. This is applicable when [Pr. PA04] is set to the initial value. The stop system of SD can be changed to DB using
[Pr. PA04].
6. This alarm will occur only in the J3 compatibility mode.
