Monitor display for operation panel (Pr.52, Pr.774 to Pr.776)
• When Pr.52 = "0" (initial value), the monitoring of output frequency, output current, output voltage and fault display can be
selected in sequence by pressing .
• The Load meter, Motor excitation current and Motor load factor are displayed on the second monitor (output current)
position, among the monitors set in Pr.52. Other monitors are displayed in the third monitor (output voltage) position.
• The monitor displayed at power ON is the first monitor (the output frequency monitor, according to the initial value). Display
the monitor that will be the first monitor, and continue pressing for 1 s. (To return to the output frequency monitor,
display the output frequency monitor and press for 1 s.)
• For example, when Pr.52 = "20" (cumulative energization time), the monitor is displayed on the operation panel as shown
below.
• Pr.774 sets the output frequency monitor, Pr.775 sets the output current monitor, and Pr.776 sets the monitor
description to be displayed at the output voltage monitor position. When Pr.774 to Pr.776 = "9999" (initial value), the Pr.52
setting value is used.
NOTE
• On the operation panel (FR-DU08), the "Hz" unit indicator is lit while displaying the output frequency, the "Hz" flickers when
displaying the set frequency.
Displaying the set frequency during stop (Pr.52)
• When Pr.52 = "100", the set frequency is displayed during stop, and output frequency is displayed during running. (LED of
Hz flickers during stop and is lit during operation.)
 Displays the frequency that is output when the start command is ON. The value considers the maximum/minimum frequency and frequency
jumps. It is different from the frequency setting displayed when Pr.52 = "5".
NOTE
• During an error, the output frequency at error occurrence appears.
• During output shutoff by the MRS signal, the values displayed are the same as during a stop.
• During offline auto tuning, the tuning state monitor takes priority.
