Alarm signals (A)
An alarm is a message, that a condition occurred, which may lead to a dangerous situation. It is displayed and
written into the fault logger. However, the cause for the alarm can inhibit the drive from continuing with normal
operation. If the cause of the alarm disappears, the alarm will be automatically reset. The fault logger shows
the appearing alarm (A1xx) with a plus sign and the disappearing alarm (A2xx) with a minus sign. An
appearing user defined alarm is indicated as A3xx. A disappearing user defined alarm is indicated as A4xx.
The alarm handling must provides 4 alarm levels.
Alarm level 1:
−
the drive keeps on running and the alarm is indicated
−
after the drive is stopped, the main contactor cannot be switched on again (no re-start possible)
Alarm level 2:
−
the drive keeps on running and the alarm is indicated
−
fan contactor stays on as long as the alarm is pending
−
if the alarm disappears FanDly (21.14) will start
Alarm level 3:
−
AutoReclosing (auto re-start) is [AuxStatWord (8.02) bit 15] active
−
RdyRun [MainStatWord (8.01) bit 1] is disabled, but the drive is automatically restarted when the alarm
condition vanishes
−
± is set to 150°
−
single firing pulses
Alarm level 4:
the drive keeps on running and the alarm is indicated
In case an alarm occurs, it stays active until the cause is eliminated. Then the alarm will automatically
disappear, thus a Reset [UsedMCW (7.04) bit 7] is not needed and will have no effect.
