Inverter Status; Read-Only Variables - WEG CFW08 Vector inverter User Manual

5.2.2 Inverter Status

5.2.3 Read-Only Variables

Reference Backup
The last frequency reference set by the keys the
is stored when inverter is stopped or the AC power is removed, provided
P120 = 1 (reference backup active is the factory default). To change the
frequency reference before starting the inverter, the value of the parameter
P121, must be changed.
Inverter is READY to be started.
Line voltage is too low for inverter operation
(undervoltage condition).
Inverter is in a Fault condition. Fault code is flashing
on the display. In our example we have the fault
code E02 (refer to chaper Maintenance).
Inverter is applying a DC current on the motor (DC
braking) according to the values programmed at
P300, P301 and P302 (refer to Chapter 6).
Inverter is running self-tuning routine to identify motor
parameters automatically. This operation is controlled
by P408 (refer to Chapter 6).
NOTE!
The display also flashes in the following conditions, besides the fault
conditions:
trying to change a parameter value when it is not allowed.
inverter in overload condition (refer to Chapter Maintenance).
Parameters P002 to P099 are reserved for the display of read-only values.
The factory default display when power is applied to the inverter is P002
(frequency proportional value in V/F control mode and motor speed in rpm
in vector control mode). Parameter P205 defines the initial monitoring
parameter, i.e., defines the read-only variable that will be displayed when
the inverter is powered up. For further information refer to P205 description
in Chapter 6.
