Note 1: You can allocate the momentary power interruption signal (IP: 08) and the undervoltage signal (UV: 09)
to any of multi-function output terminals P1 to P5 selection (C021 to C025) or the relay output terminal
(C026).
Note 2: If power interruption is retained for 1 second or longer, refer to the reset description ("Reset" (page 4-85)).
Restarting Procedure
• Frequency matching restart
This method restarts the Inverter by detecting frequency and rotation direction based on the
motor's residual voltage.
• Frequency pull-in restart
The Inverter starts output at the frequency set in starting frequency selection b030, and searches
for a point where frequency and voltage are balanced to restart the Inverter, while holding current
at the frequency pull-in restart level (b028).
If the Inverter trips with this method, reduce the b028 set value.
