Speed search
selection (current
detection or
speed calcula-
tion)
Enables/disables the speed search
function and sets the speed search
method.
0:Disabled, speed calculation
1: Enabled, speed calculation
2: Disabled, current detection
3: Enabled, current detection
Speed Calculation:
When the search is started, the
motor speed is calculated and
acceleration/deceleration is per-
formed from the calculated speed
to the specified frequency (motor
direction is also searched).
Current Detection:
The speed search is started from
the frequency when power was
momentarily lost and the maxi-
mum frequency, and the speed is
detected at the search current level.

Speed search
operating current
(current detec-
tion)
Sets the speed search operation
current as a percentage, taking the
Inverter rated current as 100%.
Usually not necessary to set. When
restarting is not possible with the
factory settings, reduce the value.

Speed search
deceleration time
(current detec-
tion)
Sets the output frequency decelera-
tion time during speed search in 1-
second units.
Sets the time for deceleration from
the maximum output frequency to
the minimum output frequency.

Speed search wait
time (current
detection or
speed calcula-
tion)
When a speed search is performed
after recovering from a momen-
tary power loss, the search opera-
tion is delayed for the time set here.
If e.g. a contactor is used at the out-
put side of the inverter set this
parameter to the contactor delay
time or more.
