10. TROUBLESHOOTING

10.2 When alarm or warning has occurred

POINT

Configure up a circuit which will detect the trouble (ALM) sign al and turn

off the servo-on (SON) signal at occurrence of an alarm.

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 outpu t the alarm code in O N/OFF st atus acros s the cor respondi ng

pin and SG. Warnings (AL.92 to AL.EA) have no alarm codes. Any alarm code is output at occurrence of

the corresponding alarm. In the normal statu s, the s igna ls av aila ble before alarm code set ting ( CN1 B-19:

ZSP, CN1A-18: INP or SA, CN1A-19: RD) are output.

The alarms marked in the alarm deac tivation column can be deactivated by the corresponding

operations.
