Description
The filter time constant is selectable
for monitoring of the motor
excitation current. A larger setting
results in slower response.

Description
display
Displays the inverter output

frequency.
Displays the inverter output
current effective value.
Displays the inverter output
voltage.
Displays 8 past faults
individually.
Displays the set frequency
Displays the motor speed (by the
Pr. 37, Pr. 144 settings).
(Refer to page 5-341)

The actual motor speed by
encoder signal is used during
encoder feedback control and
vector control.
Displays motor torque as a
percentage (0% under V/F

control), considering the rated
torque as 100%.
Displays the DC bus voltage
value.
Brake duty set in Pr. 30 and Pr. 70
Displays the motor thermal
cumulative value, considering
the thermal operation level as
100%.
Saves and displays the output
current monitor peak value.
(Cleared with each start.)
Saves and displays the DC bus
voltage peak value.
(Cleared with each start.)
Displays the power at the
inverter input side.
Displays the power at the
inverter output side.
