The value measured by Pr. 259 is displayed.
Setting "1" and turning the power supply off
starts the measurement of the main circuit
capacitor life.
1 0 0, 1
When the Pr.259 value is "3" after powering
on again, the measuring is completed.
Read the deterioration degree in Pr.258.

Normally operation can be performed with
the initial value unchanged. But adjust the
0.01Hz 3Hz 0 to 20Hz frequency according to the magnitude of
the load specifications (moment of inertia,
torque).

Decelerate from the speed obtained from

Set the frequency at which the
0.01Hz 60Hz 0 to 400Hz deceleration slope is switched from the Pr.
264 setting to the Pr. 265 setting.
Adjust response level at UV avoidance
operation. A larger setting will improve
responsiveness to the bus voltage change.
0.1% 100% 0 to 200%
Since the regeneration amount is large
when the inertia is large, decrease the
setting value.
Description
or a power failure
occurs, the inverter
can be decelerated
to a stop.
or a power failure
occurs, the inverter
can be decelerated
to a stop.
If power is restored
during a power
failure, the inverter
accelerates again.
Decelerate from the speed obtained
from output frequency minus Pr. 262.
Decelerate from output frequency
