Description
Set the full-scale value to output the output
frequency monitor value to terminal AM.
Set the full-scale value to output the output
current monitor value to terminal AM.
The coasting time is as follows:
FR-E720S-080SCor less,
FR-E740-040SC or less:. . . . . . . . . . . . . 1s,
FR-E720S-110SC,
FR-E740-060SC to 170SC:. . . . . . . . . . . 2s,
FR-E740-230SC and 300SC: . . . . . . . . . 3s
Set the waiting time for inverter-triggered
restart after an instantaneous power failure.
No restart
Set a voltage starting time at restart.

Consider the rated inverter current as 100%
and set the stall prevention operation level
during restart operation.
When offline auto tuning is performed
under V/F control, frequency search gain
necessary for frequency search for automatic
restart after instantaneous power failure is
set as well as the motor constants (R1).

constants
Without rotation direction detection
With rotation direction detection
When Pr. 78 = "0", the rotation direction is
detected.
When Pr. 78 = "1", "2", the rotation direction
is not detected.
Set the acceleration time to reach the set fre-
quency at a restart.
Acceleration time for restart is the normal
acceleration time (e.g. Pr. 7).
