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 will not rotate, increase the Pr. 0 value by 1% by 1%
by looking at the motor movement. (The guideline is for about 10%
change at the greatest.

The amount of current flows in the motor may become large according to the conditions such as the motor
characteristics, load, acceleration/deceleration time, wiring length, etc. After overcurrent trip, E.OC1 (overcurrent trip
during acceleration)), overload trip (E.THM (motor overload trip), or E.THT (inverter overload trip) may occur.
(When a fault occurs, release the start command, and decrease the Pr. 0 setting 1% by 1% to reset.) (Refer to page 96.)
If the inverter still does not operate properly after the above measures, set Pr. 80, Pr. 81, and Pr. 800 (Advanced
magnetic flux vector control). The Pr. 0 setting is invalid under Advanced magnetic flux vector control.
