When alarm or warning has occurred
POINT
• Configure up a circuit that will detect the trouble (ALM) signal and turn off the servo-on (SON)
signal at occurrence of an alarm.
Alarms and warning list
When a fault occurs during operation, the corresponding alarm or warning is displayed. If any alarm or warning has occurred, refer to
Section Alarm definitions and causes and take the appropriate action. Set "1
" in parameter No. 59 to output the alarm code in
ON/OFF status across the corresponding pin and SG. Warnings (AL.90 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 (CN1B-19, CN1A-18, and
CN1A-19) are output.
The alarms marked in the alarm deactivation column can be deactivated by the corresponding operations.
