10.2.1 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 10.2.2 or 10.2.3 and take the appropriate action.
Set " 1" in parameter No. 49 to output the alarm code in ON/OFF status across the corresponding
pin and SG. Warnings (AL.96 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: INP or SA) are output.
After its cause has been removed, the alarm can be deactivated in any of the methods marked
alarm deactivation column.
