POINT
As soon as an alarm occurs, turn SON (Servo-on) off and interrupt the power.
8.1 Alarm and warning list
When an error occurs during operation, the corresponding alarm or warning is displayed. If any alarm or
warning has occurred, refer to section 8.2 or 8.3 and take the appropriate action. When an alarm occurs,
ALM will turn off.
To output alarm codes, set [Pr. PD34] to "_ _ _ 1". Alarm codes are outputted by on/off of bit 0 to bit 2.
Warnings ([AL. 91] to [AL. F3]) do not have alarm codes. The alarm codes in the following table will be
outputted when they occur. The alarm codes will not be outputted in normal condition.
After its cause has been removed, the alarm can be deactivated in any of the methods marked
ż
in the
alarm deactivation column. Warnings are automatically canceled after the cause of occurrence is removed.
For the alarms and warnings in which "SD" is written in the stop method column, the servo motor stops with
the dynamic brake after forced stop deceleration. For the alarms and warnings written "DB" in the stop
method column, the servo motor stops with the dynamic brake without forced stop deceleration.
