3.8 Alarm occurrence timing chart
CAUTION
When an alarm has occurred, remove its cause, make sure that the operation
signal is not being inputted, ensure safety, and reset the alarm before restarting
operation.
POINT
In the torque control mode, the forced stop deceleration function is not available.
To deactivate an alarm, cycle the control circuit power, push the "SET" button in the current alarm window,
or cycle the RES (Reset) However, the alarm cannot be deactivated unless its cause is removed.
3.8.1 When you use the forced stop deceleration function
POINT
To enable the function, set "2 _ _ _ (initial value)" in [Pr. PA04].
Disable the forced stop deceleration function for a machine in which multiple
axes are connected together, such as a tandem structure. In this case, when an
alarm occurs, the servo motor will stop with the dynamic brake.
(1) When the forced stop deceleration function is enabled

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. PF09] 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. PF15].
