Functions
Momentary Power Interruption Non-stop Function
This function decelerates the Inverter by a controlled stop to avoid a trip or free running in case of
power supply disconnection or momentary power interruption during operation.
Operation Description
A If the power is disconnected during operation with the momentary power interruption non-stop
function enabled (b050 = 01) and the voltage falls below the momentary power interruption non-
stop function starting voltage (b051), the output frequency is decelerated with one stroke in
accordance with the momentary power interruption non-stop deceleration starting width (b054)
(Internal DC voltage rises due to the regenerative energy generated at this time.)
B While deceleration continues in accordance with the momentary power interruption non-stop
deceleration time (b053), internal DC voltage increases, and once the voltage reaches the stop
deceleration level of non-stop function (b052), deceleration ceases.
C Internal DC voltage decreases because there is no power supply during this constant speed
operation.
D Deceleration starts again according to b053 after the internal DC voltage decreases to b051.
Then, after a recurrence from B, the operation eventually stops without a trip.
