Figure 4.8: Graphic function visualization example
In the graphic mode, it is possible to pause the sampling and then navigate through the graphic with the help of a
cursor (use arrows
and ). The parameter values corresponding to the cursor location are presented near the
parameter numbers below the graphic.
By means of the parameter P0493 (Sampling time of the online graphic) it is also possible to adjust the horizontal
graphic scale, by adjusting the sampling time between points.
The default full scale of the graphic is always 100 % of the programmed parameter full scale. Through the pa-
rameters P0516 and P0517 it is possible to modify the full scale of the parameters programmed for the graphic
function.

NOTE!
Table 4.4 on page 4-8 presents the full scale for the read-only parameters that can be programmed
for both, monitoring and graphic function.
4.5 ALARMS AND FAULTS
4.5.1 Alarms/Faults Screen
When fault or alarm occurs in the MVW3000, HMI enters the error warning mode ( refer to Figure 4.9 on page 4-10 ).
The HMI stays in this error warning mode until the user selects [Exit]or error [Reset], through the correspondent
softkeys.
The [Exit] option deactivates the notification and allows the user to continue using the HMI; however, the inverter
stays in the fault status and it is not possible to enable it.
The [Reset] option causes a general inverter reset and, if the fault persists (the fault cause has not been solved),
it is indicated again. If the fault cause has been eliminated, the inverter operates normally again and the fault is
stored in the error record.
Alarms are showed in the inverter status field with the Axxx indication. In this case the HMI and the inverter remain
operating normally and the alarm is stored in the error record. If one chooses the alarm reset, the procedure is
similar to the fault reset (corresponding softkey).
