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. 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.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
deactivation column.
