15.6.2 Alarms and warning list
POINT
Configure up a circuit which will detect the trouble (ALM) signal and turn off
the servo-on (SON) signal at occurrence of an alarm.
When a fault occurs during operation, the corresponding alarm or warning is displayed. If any alarm or warning
has occurred, refer to section 10.2.2 or 10.2.3 and take the appropriate action. When an alarm occurs, the
current circuit between ALM and VIN opens.
Set "
1" in parameter No.49 to output the alarm code in ON/OFF status across the corresponding pin
and VIN. Warnings (AL.E0 to AL.E9) have no alarm codes. Any alarm code is output at occurrence of the
corresponding alarm. In the normal status, the signals available before alarm code setting (CN1-12: ZSP, CN1-
11: RD, CN1-10: SA) are output.
After its cause has been removed, the alarm can be deactivated in any of the methods marked
in the alarm
deactivation column.
