3.7 Alarm occurrence timing chart
CAUTION
When an alarm has occurred, remove its cause, make sure that the operation
signal is not being input, 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 the alarm, cycle the control circuit power or give the error reset or CPU reset command from
the servo system controller. However, the alarm cannot be deactivated unless its cause is removed.
3.7.1 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. If an alarm occurs
with the forced stop deceleration function disabled, the servo motor will stop with
the dynamic brake.
