This parameter is used to adjust the Accel and Decel
pattern when ' S-Curve' is selected in FU1-05 and FU1-
06 respectively. To use this function, the Reference
Frequency for Accel and Decel set in FU2-70 should be
set to ' Delta freq' .

Actual Accel Time = DRV-01 + (DRV-01 * FU2-17)/2 +
(DRV-01*FU2-18)/2
Actual Decel Time = DRV-02 + (DRV-02 * FU2-17)/2 +
(DRV-02*FU2-18)/2
Ex) If DRV-10: 1 sec, FU2-17: 40%, FU2-18: 20%,
Actual Accel Time = 1 sec + (1sec*0.4)/2 + (1sec*0.2)/2
= 1.3 sec

FU2?Power-on run
20 --- No ---
Factory Default:
No
If FUN-20 is set to ' No' , restart the inverter by cycling the
FX or RX terminal to CM terminal after power has been
restored.
If FUN-20 is set to ' Yes' , the inverter will restart after
power is restored. If the motor is rotating by inertia at the
time power is restored, the inverter may trip. To avoid
this trip, use ' Speed Search' function by setting FU2-22
to ' 1xxx' .
