Increase the starting torque (Pr. 0)
Set this parameter when "the motor with a load will not rotate", "an alarm [OL] is output, resulting in an inverter
trip due to [OC1], etc.
When the motor with a load will not rotate,
increase the Pr. 0 value 1% by 1% unit by looking at
the motor movement. (The guideline is for about 10%
change at the greatest.)

· A too large setting may cause the motor to overheat, resulting in an overcurrent trip (OL (overcurrent alarm) then E.OC1
(overcurrent trip during acceleration)), overload trip (E.THM (motor overload trip), and E.THT (inverter overload trip)).
(When a fault occurs, release the start command, and decrease the Pr. 0 setting 1% by 1% to reset.)
If the inverter still does not operate properly after the above measures, adjust Pr. 80, Pr. 81 (Advanced magnetic flux
vector control), Pr.800 (Real sensorless vector control). The Pr.0 setting is invalid under advanced magnetic flux
vector control, real sensorless vector control and vector control. (Refer to chapter 4 of
