Description
Displays whether the control circuit capacitor, main
circuit capacitor, cooling fan, and each parts of the
inrush current limit circuit has reached the life alarm
output level or not.
Displays the deterioration degree of the inrush
current limit circuit. Reading only
Displays the deterioration degree of the control
circuit capacitor. Reading only
Displays the deterioration degree of the main
circuit capacitor. Reading only
The value measured by Pr. 259 is displayed.
Start measuring the main circuit capacitor life.
Switch the power supply ON again and check
the Pr. 259 setting. Measurement is complete if
the setting is "3". Set the deterioration degree
in Pr.258.

Normally operation can be performed with the
initial value unchanged. But adjust the frequency
according to the magnitude of the load
specifications (moment of inertia, torque).
When output frequency ≥ Pr.263
Decelerate from the speed obtained from
(output frequency - Pr.262).
When output frequency < Pr.263
Decelerate from output frequency
Decelerate from the speed obtained from
(output frequency - Pr.262).
Set a deceleration slope down to the frequency
set in Pr.266.
Set a deceleration slope below the frequency
set in Pr.266.
Same slope as in Pr.264
