1) No. 35 SAcc.St.Sel
(S-shape acceleration start selection)
2) No. 36 SAcc.End.Sel
(S-shape acceleration end selection)
3) No. 37 SDec.St.Sel
(S-shape deceleration start selection)
4) No. 38 SDec.End.Sel
(S-shape deceleration end selection)
4-2-8 S-shape acceleration/deceleration setting
The output frequency at the time of acceleration/deceleration can be shaped like S. The time for the S-shape
curve can be selected from among the four choices (0, 1, 5, and 10 seconds) according to the load. The accel-
eration/deceleration time is selected separately.
16
Note: When the S-shape acceleration/deceleration is used or when the frequency setting or
acceleration/deceleration time is changed during acceleration, overshoot may occur.
4-2-9 Rotation direction selection
1) No. 39 Rotation.Sel
(rotation direction selection)
[1] For/Rev Both
(Both forward and reverse rotations are allowed.)
[2] For only (Reverse rotation is inhibited.)
[3] Rev only (Forward rotation is inhibited.)
}
The rotation direction can be selected from among the
three choices shown left. The reverse rotation with
"Rev only" selected or forward rotation with "For
only" selected are limited to 0 Hz.
4-2-10 Rotation direction selection
* Insufficient voltage lasting about 10 seconds or less is assumed to be instantaneous power failure.
1) No. 40 IPF.Restart ('restart after instantaneous power failure' selection)
[1] Off: Inhibits restart after instantaneous power failure.
[2] On: Allows restart after instantaneous power failure.
Note: When free start is performed when restarting the inverter after instantaneous power failure, set code No.
14 Start mode to Free Start.
2) No. 41 Restart.Time (restart time)
The restart time can be set according to the residual voltage of the motor.
The restart time is set within the range from 0.1 to 5.0 seconds in the unit of 0.1 second. When free start is
performed, setting below 0.6 second is assumed to be 0.6 second.
