Monitor display and monitor output signal
REMARKS
⋅ By setting "0" in Pr. 52, the monitoring of output frequency to fault display can be selected in sequence by .
⋅ When the operation panel (FR-DU07) is used, the displayed units are Hz, V and A only and the others are not displayed.
⋅ The monitor set in Pr. 52 is displayed in the third monitor position (The output voltage monitor is changed).
Note that load meter, motor excitation current, and motor load factor are displayed in the second monitor (output current).
* The monitor displayed at power-ON is the first monitor. Display the monitor you want to display on the first monitor and hold down
for 1s. (To return to the output frequency monitor, hold down for 1s after displaying the output frequency monitor.)
Example)
When
Pr. 52
is set to "20" (cumulative energization time), the monitor is displayed on the operation panel as described below.
(2) Display set frequency during stop (Pr. 52)
⋅ When Pr. 52 is set to "100", the set frequency monitor
is displayed during a stop and the output frequency
monitor is displayed during operation. (LED of Hz
flickers during stop and is lit during running.)
⋅ When Pr. 52 = "100", the set frequency displayed at a
stop indicates frequency to be output when the start
command is ON.
Different from the frequency setting displayed when
Pr. 52 = "5", the value based on maximum/minimum
frequency and frequency jump is displayed.

REMARKS
⋅ During an error, the output frequency at error occurrence appears.
⋅ During MRS, the values displayed are the same as during a stop.
⋅ During offline auto tuning, the tuning status monitor has priority.
