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.

PROFINET Operating Instruction
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.
