■ Setting example of <F302: Regenerative power ride-through> = "1"
1) When the power supply is shut off
4
* Available time to continue the operation varies by the mechanical inertia or load condition.
4
Perform verification test when using this function.
* Using retry function at the same time enables to automatically restart without failure stop.
6 When the power supply is shut off during deceleration stop, deceleration stop corresponding to
F302=2 is operated instead of regenerative power ride through.
This function does not work well at high speed in PM control.
Do not set this function in case of PM high speed drive.
2) When a momentary power failure occurs
9
When a momentary power failure occurs during deceleration stop, the regenerative power ride-
through does not function.
