Deceleration Time for Speed Search Factory setting 3.00
Settings 0.50~600.00 s
1
This parameter determines the rate at which the drive will decelerate the output frequency
to find the motor speed, during the momentary speed search method “begins from
command frequency”.
1
If the speed search or momentary power loss is set for “begin from minimum output
frequency”, then this parameter is not used.
1
When speed search is executed, the Auto Deceleration and the S curve deceleration will
not be conducted.

Auto Restart after Fault Factory setting 0
Settings 0~10
1
This parameter determines the number of restarts after the following faults, “OC, GFF and
OV”.
1
The “Auto Restart after Fault” begins with the “Maximum Output Frequency Speed Search”
method.
1
If this parameter is set to 10 and 3 faults occur, the remaining number of faults for auto
restart is 7. If there are no more faults within 10 minutes, the drive will reset this
parameter to 10.

Speed Search Type
Factory setting
0
Settings 0 speed search disabled
1 speed search through the frequency command
2 FWD-speed search only (motor only runs in FWD direction)
3 REV-speed search only (motor only runs in REV direction)
4 FWD/REV speed search enabled in both directions (fwd first)
5 REV/FWD speed search enabled in both directions (rev first)
1
This parameter selects the method for speed search. Settings 2 and 3 are used when
the motor direction is always guaranteed. If it is possible the motor direction may be
either REV or FWD upon a speed search, then selection 4 or 5 should be used.
1
The speed search function is most applicable to a large Punch Press machine, blower,
or other high inertia application. While these applications normally stop, using the
“Coast to Stop” method, this may take 2~5 minutes or the application comes to a
complete stop. However, with the speed search function enabled, users could instantly
start the drive without waiting for the flywheel to come to a stop and the drive would
quickly find the speed and bring the motor to speed.
