(2) When the forced stop deceleration function is not enabled
When an all-axis stop alarm occur, all axes will be the operation status below. When a corresponding
axis stop alarm occurs, only the axis will be the operation status below. You can normally operate the
axis that any alarm is not occurring.

(Note 2)
Note 1. The model speed command is a speed command generated in the servo amplifier for forced stop
deceleration of the servo motor.
2. This is for when the electronic dynamic brake is enabled with [Pr. PF06] while a certain servo motor is
used. If the servo motor speed is 5 r/min or higher, the electronic dynamic brake will operate continuously
for the time period set in [Pr. PF12].
