11 Warnings and Alarms
11.1 Status Messages
11.1.1 Warnings/Alarm Messages
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 trip.
Alarms must be reset to restart operation once their cause
has been rectified.
This may be done in three ways:
• By using the [RESET] control button on the
keypad control panel
• Via a digital input with the “Reset” function
• Via serial communication/optional network
NOTE
After a manual reset using the [RESET] button on the
keypad, the [AUTO] 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 11.1).
Alarms that are trip-locked offer additional protection,
meaning 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 H-04 Auto-Reset (Times)
(Warning: automatic wake-up is possible!)
If a warning and alarm is marked against a code in
Table 11.1, this means that either a warning occurs before
an alarm, or that you can specify whether it is a warning
or an alarm that will be displayed for a given fault.
This is possible, for instance, in F-10 Electronic Overload.
After an alarm or trip, the motor carries on coasting, and
the alarm and warning flash. Once the problem has been
rectified, only the alarm continues flashing until the
frequency converter is reset.
