Speed search disabled: Motor starts from minimum output frequency.
1
Speed search enabled: Speed search is performed from maximum output frequency and
motor is started. (In control modes with PG, i.e., V/f with PG and flux vector, motor starts
from the motor speed.)
Set “1” to use the speed search function. To use speed search freely in control modes without PG, i.e.,
V/f control and open-loop vector control, set the multi-function contact input selection (H1-01 to H1-06)
to 61 or 62 (external search command).

These parameters cannot be changed during operation.
Note The factory-set default varies depending on the Inverter capacity. The values shown in the table
are for 200-V class, 0.4-kW.
•
For the speed search operating current (b3-02), set the operating current for the speed search. If re-
starting is not possible with the set value, then lower the set value. Set the speed search operating
current as a percentage of the Inverter’s rated output current, with the Inverter’s rated output current
taken as 100%.
•
For the speed search deceleration time (b3-03), set the output frequency deceleration time for while
the speed search is being performed.
•
When the speed search and DC injection braking are set, set the minimum baseblock time (L2-03).
For the minimum baseblock time, set the time to wait for the motor’s residual voltage to dissipate. If an
overcurrent is detected when starting a speed search or DC injection braking, raise the set value to
prevent a fault from occurring.
