Leave for about 30 minutes of cooling time after removing the cause of occurrence.
Stop method indicates as follows:
DB: Stops with dynamic brake. (Coasts for the servo amplifier without dynamic brake.)
SD: Decelerates to a stop
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].
