■ Display readout
Fr
The frequency converter shows the present
output frequency in Hertz [Hz].
Io
The frequency converter shows the present
output current in Amps [A].
Uo
The frequency converter shows the present
output voltage in Volt [V].
Ud
The frequency converter shows the intermediate
circuit voltage in Volt [V].
Po
The frequency converter shows the calculated
output in kilowatt [kW].
notrun
This message is shown if an attempt is made to change
a parameter value while the motor is running. Stop
the motor to change the parameter value.
■ Warnings/alarm messages
A warning or an alarm will appear in the display
as a numerical code Err. xx. A warning will
be shown on the display until the fault has
been corrected, while an alarm will continue to
flash until the [STOP/RESET] key is activated.
The table shows the various warnings and alarms, and
whether the fault locks the frequency converter. After a
Trip locked the mains supply is cut off and the fault is
corrected. The mains supply is reconnected and the
frequency converter is reset. The frequency converter is
now ready. A Trip can be reset manually in three ways:
1. Via the operating key [STOP/RESET].
2. Via a digital input.
3. Via serial communication.
It is also possible to choose an automatic reset in
parameter 405 Reset function. When a cross appears
in both warning and alarm, this can mean that a
warning comes before an alarm. It can also mean
that it is possible for the user to programme whether
a warning or an alarm will appear for a given fault.
For example, this is possible in parameter 128 Motor
thermal protection. After a trip the motor will coast,
and alarm and warning will blink on the frequency
converter, but if the fault disappears only the alarm
will blink. After a reset the frequency converter
will be ready to start operation again.
