Used to set a torque boost level that best fits the load characteristics. A larger value causes a
higher output voltage and stronger boost.

Note
・
If the boost level is too high, an overcurrent fault, overload fault or motor overheating could occur
or the noise could increase.
・
The motor current will increase when the value of boost level is increased. Carefully consider the
settings for "P016: electronic thermal select "and "P017: thermal current setting".
・
Under control of vector (P129= "1"), torque boost level is invalid.
If larger torque is required at low speed, value of torque boost level can be set to larger data.
Increasing output voltage to boost torque.
