Description
Default
Modify
add the temperature of the inverter and decrease
the efficiency.
When the torque boost is set to 0.0%, the
inverter is automatic torque boost.
Torque boost threshold: below this frequency
point, the torque boost is valid, but over this
frequency point, the torque boost is invalid.

When P04.00 =1, the user can set V//F curve
through P04.03–P04.08.
V/F is generally set according to the load of the
motor.
Note: V1<V2<V3, f1<f2<f3. Too high low
frequency voltage will heat the motor excessively
or damage. Overcurrent stall or overcurrent
protection may occur.
Setting range of P04.03: 0.00Hz–P04.05
Setting range of P04.04, P04.06 and P04.08:
0.0%–110.0% (rated motor voltage)
Setting range of P04.05: P04.03–P04.07
Setting range of P04.07: P04.05–P02.02 (rated
