Automatic restart after instantaneous power failure function
• The inverter output is shut off at the activation of the instantaneous power failure protection (E.IPF) or undervoltage
protection (E.UVT). (Refer to
• When E.IPF or E.UVT is activated, the instantaneous power failure (IPF)/undervoltage signal is output.
• The IPF signal is assigned to terminal IPF in the initial setting. To assign the IPF signal to a different terminal, set "2
(positive logic) or 102 (negative logic)" to any of Pr.190 to Pr.196 (Output terminal function selection).
• When the automatic restart after instantaneous power failure function is selected, motor restarts at the power restoration
after an instantaneous power failure or undervoltage. (E.IPF and E.UVT are not activated.)

Only with restart after instantaneous power failure
• When the automatic restart after instantaneous power failure / flying start signal (CS) is assigned to the input terminal by
setting Pr.178 to Pr.189 (Input terminal function selection), restart operation is enabled at turn-ON of the CS signal.
• When the CS signal is assigned to an input terminal and Pr.57 Restart coasting time "9999" (with restart), the inverter
cannot be operated while the CS signal remains OFF.
• Separated converter types detect the instantaneous power failure on the converter unit side. Perform wiring so that the IPF
signal transmitted from the converter unit is input to the terminal to which the X11 signal is assigned. On the converter unit
side, enable the restart operation. (For setting the converter unit, refer to the Instruction Manual of the converter unit.)
• For the terminal to be used for the X10 and X11 signal, set "10" (X10), "11" (X11) in Pr.178 to Pr.189 and assign the
function. (For separated converter types, the X10 signal is assigned to the terminal MRS in the initial setting.)
• For the X10 signal of separated converter types, NC contact input specification is selected in the initial setting. Set Pr.599
= "0" to change the input specification to NO contact.
NOTE
• Changing the terminal assignment using Pr.178 to Pr.189 (Input terminal function selection) may affect other functions.
Set parameters after confirming the function of each terminal.
• If the CS signal is not assigned to any input terminal, solely setting Pr.57 will enable the restart operation at all times.
