If FG2-19 is set to Yes
and VFD is controlled
via terminals and start command is present during
power up, VFD will start after power up sequence
is done. This feature is used for Fan and Pump
applications when the system runs in automatic
mode and there is no operator in the field to restart
VFD.
If VFD control is set to keypad and VFD loses
power, it will not automatically start at power up.

If VFD should start
after power up is done
and FG2-20 is set to 1~9999sec., VFD will start
after FG2-20 delay time is expired. This feature can
be used to protect system from starting during
power fluctuation.

If FG2-21 is set to Yes
and VFD is controlled
via terminals and start signal is present at the
moment of VFD fault reset, VFD will start
automatically after VFD fault is reset.
If VFD control is set to keypad and VFD is tripped
on fault, it will not automatically start at fault reset.

If FG2-22 is set to Yes
and VFD loses power
momentarily, the motor load is still rotating by
inertia. The VFD will start in Flying Start Mode
when power is restored regardless of FG1-20
setting but only when FG2-22 is set to Yes.

The VFD can be programmed to restart
automatically after it has tripped on a fault.
If FG2-24 is set to Yes, the retry mode and
parameters FG2-25 and FG2-26 become enabled.
FG2-25 sets the number of retry attempts. VFD will
try to restart as many times as FG2-25 is set for and
if it still trips after last attempt, it will activate the
fault relay and stay in fault mode.
FG2-26 sets the time delay before retry attempts.
Do not set this number too small because some
faults such as Overheat, Overload, Over current etc
require a long time to cool down the VFD or motor,
otherwise VFD or motor can be damaged. The
Retry Delay starts after VFD trips. The last attempt
will be removed from FG2-25 counter if VFD does
not trip at next restart attempt within 30sec.

The Flying Start feature allows VFD to start with
already rotating motor load without tripping on
fault. The VFD calculates the remaining load speed
based on FG2-46 Load Inertia rate and provides
output based on FG2-27 setting. If load is rotating
in opposite direction, VFD will stop the load first
and then start motor in proper direction.

Rated slip is used by VFD for internal speed control
calculations. In order to determine this value,
subtract the motor nameplate rated speed from
SET-04 Synchronous Speed.
