Automatic restart after instantaneous power failure function
Connection (CS signal)
NOTE
• The CS signal is assigned to terminal CS in the initial setting. By setting "6" to any of
Pr.178 to Pr.189 (Input terminal
function selection)
, the CS signal can be assigned to other terminals. Changing the terminal assignment using
Pr.178 to
Pr.189
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.
• The inverter output is shut off at the activation of the
instantaneous power failure protection (E.IPF) or undervoltage
protection (E.UVT). (Refer to
for E.IPF or E.UVT.)
• 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.)
• Restart is enabled at turn-ON of the automatic restart after
instantaneous power failure/flying start (CS) signal.
• The inverter operation is disabled at turn-OFF of the CS signal
while
Pr.57 Restart coasting time
"9999" (with restart).
• 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.
