A warning or an alarm appears in the display as a
numerical code
Err. xx
. A warning shows in the display
until the fault has been corrected, while an alarm
continues to flash until the [STOP/RESET] key is pressed.
Table 6.1
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 3 ways:
1.
Via the operating key [STOP/RESET].
2.
Via a digital input.
3.
Via serial communication.
It is also possible to select an automatic reset in parameter
405 Reset function
. When a cross appears in both warning
and alarm, this means either of the following:
•
A warning occurs before an alarm
•
A warning or an alarm can be programmed for a
given fault.
For example, this is possible in parameter
128 Motor
thermal protection
. After a trip, the motor coasts, and both
alarm and warning flash on the frequency converter. If the
fault disappears, only the alarm flashes. After a reset the
frequency converter is ready to start operation again.
