Operation selection at power failure
● Restart operation at every start
When Pr. 162 = "10" or "11", automatic restart operation is also performed every start, in addition
to the automatic restart after instantaneous power failure. When Pr. 162 = "0", automatic restart
operation is performed at the first start after power supply-on, but not performed at the second
time or later.
● Automatic restart operation selection of MRS (X10) signal
Restart operation after turning MRS (X10) signal on then off using Pr. 30 can be selected as in the
table below. When automatic restart after instantaneous power failure is selected when using the
high power factor converter (FR-HC), normally set "2" in Pr. 30.
NOTE
When output is shut off using terminal S1 and S2 in the safety stop function model, the inverter
restarts in the same way as when output is shut off by MRS (X10) signal.
Restart coasting time (Pr. 57)
Coasting time is the time from when the motor speed is detected until automatic restart control is
started.
Set Pr. 57 to "0" to perform automatic restart operation.
The coasting time is automatically set to the value below. Generally this setting will pose no problems.
FR-E720S-080SC or less, FR-E740-040SC or less ...................................1s
FR-E720S-100SC, FR-E740-060SC to 170SC.............................................2s
FR-E740-230SC and 300SC ............................................................................3s
Operation may not be performed well depending on the magnitude of the moment of inertia (J) of the
load or running frequency. Adjust the coasting time between 0.1s and 5s according to the load spec-
ifications.
