Range Description
Displays whether the control circuit capacitor,
main circuit capacitor, cooling fan, and each
(0 to 15)
parts of the inrush current limit circuit has
reached the life alarm output level or not.
Displays the deterioration degree of the
(0 to 100%)
inrush current limit circuit. Reading only
Displays the deterioration degree of the
(0 to 100%)
control circuit capacitor. Reading only
Displays the deterioration degree of the
(0 to 100%) 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
0, 1 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
0 to 20Hz
frequency according to the magnitude of the
load specifications (moment of inertia, torque).
When output frequency ≥ Pr.263
Decelerate from the speed obtained from
0 to 120Hz (output frequency - Pr.262).
When output frequency < Pr.263
Decelerate from output frequency
Decelerate from the speed obtained from
9999
(output frequency - Pr.262).
0 to 3600/ Set a deceleration slope down to the
360s frequency set in Pr.266.
0 to 3600/ Set a deceleration slope below the
360s frequency set in Pr.266.
9999 Same slope as in Pr.264
Set the frequency at which the deceleration
0 to 400Hz slope is switched from the Pr.264 setting to
the Pr.265 setting.
