 Connection (CS signal)
• When the Selection of automatic restart after instantaneous power failure / flying start (CS) signal is assigned to the input
terminal by setting "6" in 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 used for the X10 or X11 signal, set "10" (X10) or "11" (X11) in any parameter from 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 the 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 enables the restart operation at all times.
 Setting for the automatic restart after instantaneous power failure
operation (Pr.162)
The restart operation is as shown in the following table according to the setting in Pr.162 Automatic restart after
instantaneous power failure selection.
