Note 1. Leave for about 30 minutes of cooling time after removing the cause of occurrence.
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: 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
2.
SD: Forced stop deceleration
3. 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].
4. Reset enable or disable can be selected using [Pr. PE03].
