Automatic Status Monitoring
Automatic status monitoring displays abnormal status conditions that can occur during
normal inverter operation. These conditions will cause warnings and error messages
to be displayed but will not cause the inverter to trip. The table below shows these
abnormal conditions and the associated display that will appear. These displays usually
appear during the time that the abnormal condition is occurring and will go away when it
is corrected. The abnormal condition should be corrected as soon as possible.

ST-CC terminal connector is open (must be connected to run).
The main AC supply power is low.
The inverter's DC bus voltage is low.
Stall prevention is activated when flashing "C" appears in
front of output frequency.
Overvoltage limitation is activated when flashing "P" appears
in front of output frequency.
Overload detection is activated when flashing "L" appears in
front of output frequency.
This error occurs while trying to switch from manual to
automatic mode or automatic mode to manual while inverter
is outputting a frequency.
This is a frequency setting signal error. Points 1 and 2 of a
frequency setting signal are to close together. Correct the
setting of points 1 and 2 by providing an adequate distance
between them.
This error can be seen when attempting to set any of the
parameters with incorrect data values.
