0 Offline auto tuning is not performed
Advanced magnetic flux vector control
Offline auto tuning is performed with-
1
out motor running (all motor con-
stants) (Refer to section 6.3.2.)
For general-purpose magnetic flux vec-
tor control
0
11 Offline auto tuning is performed with-
out motor running (motor constants
(R1) only) (Refer to section 6.3.3.)
Offline auto tuning (tuning performed
without motor running) for V/f control
21 and automatic restart after instantane-
ous power failure (with frequency
search)
0 With frequency search
No frequency search:
The output voltage is increased until
1
the preset frequency is reached, irre-
spective of the current motor speed.
0
10 Frequency search at every start
On every start the output voltage is
increased until the preset frequency
11
reached, irrespective of the current
motor speed.
Consider the rated inverter current
according to the overload capacity as
150% 0–200%
100% and set the stall prevention oper-
ation level during restart operation.

When Pr. 78 = "0", the rotation direction
is detected.

When Pr. 78 = "1","2", the rotation direc-
tion is not detected.
