Note. The model speed command is a speed command generated in the servo amplifier for forced stop deceleration
of the servo motor.

POINT
To disable the function, set "0 _ _ _" in [Pr. PA04].
The timing chart that shows the servo motor condition when an alarm or SSCNET III/H communication brake
occurs is the same as section 3.7.1 (2).
