Considers the rated inverter current as
100% and sets the stall prevention
operation level during restart operation.
When offline auto tuning is performed
under V/F control, frequency search gain

0 to 32767
automatic restart after instantaneous
power failure is set as well as the motor
constants (R1).
Uses the Mitsubishi motor (SF-JR, SF-
9999
HRCA) constants
0 Without rotation direction detection
1 With rotation direction detection
When Pr. 78 =0, the rotation direction is
detected.
9999
When Pr. 78 =1, 2, the rotation direction is
not detected.
Acceleration time to reach Pr.20
0 to 3600s Acceleration/deceleration reference frequency
at a restart.
Acceleration time for restart is the normal
9999
acceleration time (e.g. Pr. 7).
When using the
frequency search,
consider the wiring
length limit.
