The coasting time when Pr.57 = "0" is as shown below. (When Pr.162 and Pr.570 are set to the initial value.)
FR-F820-00077(1.5K) or lower and FR-F840-00038(1.5K) or lower: 0.5 s

• The inverter output is shut off at the activation of the Instantaneous power failure (E.IPF) or Undervoltage (E.UVT). (Refer
to
page 577
for E.IPF or E.UVT.)
• When E.IPF or E.UVT is activated, the Instantaneous power failure/undervoltage (IPF) signal is output.
• The IPF signal is assigned to terminal IPF in the initial status. By setting "2 (positive logic) or 102 (negative logic)" in any
of Pr.190 to Pr.196 (Output terminal function selection), the IPF signal can be assigned to another terminal.
• When the automatic restart after instantaneous power failure function is selected, motor driving is resumed at the power
restoration after an instantaneous power failure or undervoltage. (E.IPF and E.UVT are not activated.)
 Connection (CS signal)
• When the automatic restart after instantaneous power failure / flying start signal (CS) 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.
