(M) Monitor display and monitor output signal Parameters
5 - 334
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 SET key.
●
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 the
SET key for 1 s. (To return to the output frequency monitor, display the output frequency monitor
and press SET key 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 fre-
quency, the "Hz" flickers when displaying the set frequency.
