Monitor display and monitor output signal
∗1
Frequency setting to output terminal status on the PU main monitor are selected by "other monitor selection" of the parameter unit (FR-PU04V/FR-PU07).
∗2
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) on the assumption that 1h = 0.001, and thereafter, it is added up from 0.
∗3
Actual operation time is not accumulated when the cumulative operation time is less than 1h until turning off of the power supply.
∗4
When using the parameter unit (FR-PU04/FR-PU07), "kW" is displayed.
∗5
Since the panel display of the operation panel is 4 digits in length, the monitor value of more than "9999" is displayed "----".
∗6
Larger thermal value between the motor thermal and transistor thermal is displayed.
A value other than 0% is displayed if the ambient temperature (heatsink temperature) is high even when the inverter is at a stop.
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.
Initial Value
∗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
monitor.)
Power-on monitor (first monitor)
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.
