This function is used to permit automatic restarting after
Power ON, Fault Reset, and Instant Power Failure
without waiting for the motor to stop.
The speed search gain should be set after considering
the inertia moment (GD
) and magnitude of torque of the
2
load. FU2-37 [Load Inertia] must be set at the correct
value to make this function operate correctly.

When FU2-22 is set to ' 1111' , Speed Search works for all
conditions.
FU2-22 [Speed Search Selection] selects the speed
search function.
FU2-23 [Current Limit Level] is the current that the
inverter limits its current rise during speed searching.
(The set value is the percentage of FU2-33 [Rated Motor
Current])
FU2-24 [P Gain] is the proportional gain used for speed
search. Set this value according to load inertia set in
FU2-37.
FU2-25 [I Gain] is the Integral gain used for speed
search. Set this value according to load inertia set in
FU2-37.

This function is used to allow the inverter to reset itself
for a selected number of times after a fault has occurred.
The inverter can restart itself automatically when a fault
occurs. To use the speed search function during auto
restarting set FU2-22 to ' xx1x' . See FU2-22 ~ FU2-25.
