Range Description
Display whether the control circuit
capacitor, main circuit capacitor, cooling
(0 to 15) fan, and each parts of the inrush current
limit circuit has reached the life alarm
output level or not.
Display the deterioration degree of the
(0 to 100%)
inrush current limit circuit. Reading only
Display the deterioration degree of the
(0 to 100%)
control circuit capacitor. Reading only
Display the deterioration degree of the
main circuit capacitor. Reading only
(0 to 100%)
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.
Coasting to stop
0 When undervoltage or power failure
occurs, the inverter output is shut off.
When undervoltage or a power failure
1 occurs, the inverter can be decelerated to
a stop.
When undervoltage or a power failure occurs,
the inverter can be decelerated to a stop.
2
If power is restored during a power failure, the
inverter accelerates again.
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
0 to 120Hz from output frequency minus Pr.262.
When output frequency < Pr.263
Decelerate from output frequency
Decelerate from the speed obtained from
9999
output frequency minus 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
0 to 400Hz deceleration slope is switched from the
Pr.264 setting to the Pr.265 setting.
