Parameter
Automatic restart after instantaneous power failure operation
When Instantaneous power failure protection (E.IPF) and undervoltage protection (E.UVT) are
activated, the inverter output is shut off. (Refer to section 7.2 for E.IPF and E.UVT.) When auto-
matic restart after instantaneous power failure operation is set, the motor can be restarted if
power is restored after an instantaneous power failure and under voltage. (E.IPF and E.UVT are
not activated.) When E.IPF and E.UVT are activated, instantaneous power failure/undervoltage
signal (IPF) is output.
NOTE
The IPF signal is assigned to the terminal IPF in the initial setting. The IPF signal can also
be assigned to the other terminal by setting "2 (source logic) or 102 (sink logic)" to any of Pr.
190 to Pr. 196 "Output terminal function selection".
.
Connection (CS signal)
When the automatic restart after instantaneous power failure selection signal (CS) is turned on,
automatic restart operation is enabled.
When Pr. 57 is set to other than "9999" (automatic restart operation enabled), the inverter will
not operate if used with the CS signal remained off).
Fig. 6-156: Connection example
NOTE
The CS signal is assigned to the terminal CS in the initial setting. By setting "6" in any of Pr.
178 to Pr. 189 (input terminal function selection), you can assign the CS signal to the other
terminal.
