ADJUSTMENT
Useful functions — To display life of inverter parts (Pr.255 to Pr.259)
255
Life alarm status
display
1 0 (0 to 15)
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.
×××
256
Inrush current limit
circuit life display
1% 100% (0 to 100%)
Displays the deterioration degree of the inrush
current limit circuit. Reading only

257
Control circuit
capacitor life display
1% 100% (0 to 100%)
Displays the deterioration degree of the control
circuit capacitor. Reading only
×××
258
Main circuit capacitor
life display
1% 100% (0 to 100%)
Displays the deterioration degree of the main
circuit capacitor. Reading only
The value measured by Pr. 259 is displayed.

Main circuit capacitor
life measuring
100, 1
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.

Refer to Pr.72.
Motor brake and stop operation — Decelerate the motor to a stop at instantaneous
power failure (Pr.261 to Pr.266)
Operation selection at power failure and instantaneous power failure — Decelerate the
motor to a stop at instantaneous power failure (Pr.261 to Pr.266)

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).
