Tab. 6-19: Monitor description list (2)
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) on the assumption that 1h = 0.001, and thereafter,
it is added up from 0.
Actual operation time is not accumulated when the cumulative operation time is less than
1h until turning off of the power supply.
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 "----".
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.

Description
Adds up and displays the
inverter operation time.
You can check the numbers of
the monitor value exceeded
65535h with Pr. 564. Can be
cleared by Pr. 171. (Refer to
page 6-116.)
Displays the output current
value on the assumption that
the inverter rated current value
is 100%.
Monitor value = output power
monitor value/rated inverter cur-
rent × 100 [%]
Adds up and displays the power
amount based on the output
power monitor.
Can be cleared by Pr. 170.
(Refer to page 6-116.)
Display the set point, measured
value and deviation during PID
control. (Refer to page 6-242 for
details.)
Displays the ON/OFF status of
the inverter input terminal and
output terminal on the PU (Refer
to page 6-116 for display on the
operation panel.)
Motor thermal heat cumulative
value is displayed.
(Motor overload trip (E.THM) at
100%)
Transistor thermal heat cumula-
tive value is displayed.
(Inverter overload trip (E.THT) at
100%)
Displays the PTC thermistor
resistance at terminal 2 when
PTC thermistor protection is
active. (0.10kΩ to 31.5kΩ) (refer
to page 6-71)
