(b) When the forced stop deceleration function is not enabled
When an all-axis stop alarm occurs, 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 1. The model speed command is a speed command generated in the servo amplifier for forced stop deceleration
of the servo motor.
2. If the servo motor speed is 5 r/min or higher at this point, the electric dynamic brake will operate continuously
for the time period set by [Pr. PF12].
