:Selection of flying restart
Adjustment range : 0 to 3
Factory setting : 0
If this parameter is enabled (3
3
3
3
= 1 to 3),
when there is a run command or after a
mains supply break, the drive executes a
procedure to calculate the motor frequency
and direction of rotation. It will automatically
recalibrate the output frequency to the
measured value and reaccelerate the
motor up to the reference frequency.
0 : disable flying restart on a motor
which is rotating.
1: enable flying restart on a motor rotating
clockwise or anti-clockwise.
2: enable flying restart on a motor rotating
clockwise only.
3: enable flying restart on a motor rotating
anti-clockwise only.
CAUTION:
If the drive control mode corresponds to
"Voltage-frequency ratio"
(4
4
8
8
= 2), and if a flying restart is
required, autocalibration should be
performed (see 3
3
8

) before configuring
the drive in voltage-frequency mode.
• If the load is stationary at the
time of the run command or when
the mains supply returns, this
operation may cause the machine to
rotate in both directions before the
motor accelerates.
• Before enabling this function,
check that there is no danger to
equipment and personnel.
:Control logic polarity
Adjustment range : OFF or On
Factory setting : On
OFF: negative logic, the input is activated
when the terminal is at low level (< 9.5 V).
On: positive logic, the input is activated
when the terminal is at high level
(> 10.5 V).
After the control logic has been changed,
confirm by pressing the key for 1
second (the drive should be locked and the
"run" terminals should be open).

:Assignment of the analogue
output
Adjustment range : Fr, Ld, AdV
Factory setting : Fr
This parameter is used to modify the
analogue output source, as follows:
Fr: Motor frequency
Eg: 0V --> 0Hz, 10V -->

AdV: User parameters set via serial link.
(See section 7.5.2 or 7.5.3).
Press for 1 second to confirm the
setting.
