Monitor display and monitor output signal

Frequency setting to output terminal status on the PU main monitor are selected by "other monitor selection" of the parameter unit (FR-PU04/FR-PU07).

The cumulative energization time and actual operation time are accumulated from 0 to 65535 hours, then cleared, and accumulated again from 0.
When the operation panel is used, the time is displayed up to 65.53 (65530h) in the indication of 1h = 0.001, and thereafter, it is added up from 0.

The actual operation time is not added up unless the inverter is operated one or more hours continuously.

When using the parameter unit (FR-PU04/FR-PU07), "kW" is displayed.

Since the panel display of the operation panel is 4 digits in length, the monitor value of more than "9999" is displayed as "----".

Larger thermal value between the motor thermal and transistor thermal is displayed.
A value other than 0% is displayed if the surrounding air temperature (heatsink temperature) is high even when the inverter is at a stop.

When the output current is less than the specified current level (5% of the rated inverter current), the output current is monitored as 0A. Therefore, the
monitored value of an output current and output power may be displayed as "0" when using a much smaller-capacity motor compared to the inverter or in
other instances that cause the output current to fall below the specified value.

The set frequency displayed indicates the 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
 By setting "0" in Pr. 52 , the monitoring of output speed to fault display can be selected in sequence by .
 When the operation panel is used, the displayed units are Hz and A only, and the others are not displayed.
 The monitor set in Pr. 52 is displayed in the third monitor position. However, change the output current monitor for the motor
load factor.

The monitor displayed at powering 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 "100" is set in Pr. 52 , the set frequency and
output frequency are displayed during stop and
operation respectively. (LED of Hz flickers during
stop and is lit during operation.)

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