Note 1. The following shows stop methods.
DB: Stops with dynamic brake. (Coasts for the servo amplifier without dynamic brake.)
SD: Forced stop deceleration
STO/DB: Dynamic brake stop operating STO function
SS1/SD: Forced stop deceleration operating SS1 function
SS1/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
SS1/DB.

For other stop methods, refer to section 4.5.2 (3) (a).
2. 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].
3. Reset this while all the safety observation functions are stopped.
4. The SSM function will be disabled and each output device will turn off.
