fter 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.
Series Servo motor
HG-KN HG-KN053/HG-KN13/HG-KN23/HG-KN43
HG-SN HG-SN52
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].
