9 Warnings and Alarms

A warning or an alarm is signalled by the relevant LED on the front of the frequency converter and indicated by a code on the display.
A warning remains active until its cause is no longer present. Under certain circumstances operation of the motor may still be continued. Warning messages may
be critical, but are not necessarily so.
In the event of an alarm, the frequency converter will have tripped. Alarms must be reset to restart operation once their cause has been rectified.
This may be done in four ways:
1.
By using the [RESET] control button on the keypad.
2.
Via a digital input with the "Reset" function.
3.
Via serial communication/optional network.
4.
By resetting automatically using the [Auto Reset] function, which is a default setting for AF-600 FP Drive. see par. H-04 Auto-Reset (Times) in
Programming Guide
NB!
After a manual reset using the [RESET] button on the Keypad, the [AUTO] or [HAND] button must be pressed to restart the motor.
If an alarm cannot be reset, the reason may be that its cause has not been rectified, or the alarm is trip-locked (see also table on following page).
Alarms that are trip-locked offer additional protection, means that the mains supply must be switched off before the alarm can be reset. After being switched
back on, the frequency converter is no longer blocked and may be reset as described above once the cause has been rectified.
Alarms that are not trip-locked can also be reset using the automatic reset function in par. H-04 Auto-Reset (Times) (Warning: automatic wake-up is possible!)
If a warning and alarm is marked against a code in the table on the following page, this means that either a warning occurs before an alarm, or it can be specified
whether it is a warning or an alarm that is to be displayed for a given fault.
This is possible, for instance, in par. F-10 Electronic Overload. After an alarm or trip, the motor carries on coasting, and the alarm and warning flash on the frequency
converter. Once the problem has been rectified, only the alarm continues flashing.
