0.1–5s
Set the waiting time for inverter-trig-
gered restart after an instantaneous
power failure.
9999
No restart
58
Restart cushion time
1s
0–60s
Set a voltage starting time at restart.
96
Auto tuning setting/
status
0
0
Offline auto tuning is not performed
11
For general-purpose magnetic flux vec-
tor control
Offline auto tuning is performed with-
out motor running (motor constants
(R1) only) (Refer to section 6.2.2.)
21
Offline auto tuning (tuning performed
without motor running) for V/f control
and automatic restart after instantane-
ous power failure (with frequency
search)
162
Automatic restart after
instantaneous power
failure selection
0
0
With frequency search
1
No frequency search:
The output voltage is increased until
the preset frequency is reached, irre-
spective of the current motor speed.
10
Frequency search at every start
11
On every start the output voltage is
increased until the preset frequency
reached, irrespective of the current
motor speed.
165
Stall prevention opera-
tion level for restart
150%
0–200%
Consider the rated inverter current
according to the overload capacity as
100% and set the stall prevention oper-
ation level during restart operation.
298
Frequency search gain
9999
0–32767
When offline auto tuning is performed
under V/f control, frequency search
gain necessary for frequency search for
automatic restart after instantaneous
power failure is set as well as the motor
constants (R1).
9999
Uses the Mitsubishi motor (SF-JR, SF-
HR, SF-JRCA, SF-HRCA) constants
299
Rotation direction
detection selection at
restarting
0
0
Without rotation direction detection
1
With rotation direction detection
9999
When Pr. 78 = "0", the rotation direction
is detected.
When Pr. 78 = "1","2", the rotation direc-
tion is not detected.
611
Acceleration time at a
restart
9999
0–3600s
Acceleration time to reach the accelera-
tion time reference frequency at a
restart.
9999
Acceleration time for restart is the nor-
mal acceleration time (e.g. Pr. 7)
