0 Offline auto tuning is not performed
Advanced magnetic flux vector control
Offline auto tuning is performed without motor

restart after instantaneous power failure (with
frequency search)
0 With frequency search
No frequency search:
The output voltage is increased until the preset
1
frequency is reached, irrespective of the current
motor speed.
0
10 Frequency search at every start
On every start the output voltage is increased until
11 the preset frequency reached, irrespective of the
current motor speed.
Consider the rated inverter current according to the
overload capacity as 100% and set the stall
150% 0–200%
prevention operation level during restart
operation.
When offline auto tuning is performed under V/F
control, frequency search gain necessary for
0–32767 frequency search for automatic restart after
instantaneous power failure is set as well as the
9999
motor constants (R1).
