Note 1.
Leave the servo amplifier for about 30 minutes of cooling time after removing the cause of
occurrence.
2.
The following shows three stop methods of DB, EDB, and SD.
DB: Dynamic brake stop (A servo motor without the dynamic brake 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 will be DB.
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].
4. In some controller communication status, the alarm factor may not be removed.
