Goodrive18 series two-in-one VFD Function parameters and function terminal reuse
-50-
heat-up, thus decreasing the efficiency.
When torque boost is set to 0.0%, the VFD uses
automatic torque boost.
Torque boost cut-off threshold: Below this
frequency threshold, the torque boost is valid,
exceeding this threshold will invalidate torque
boost.

0.1%–10.0%
Setting range of P04.02: 0.0%–50.0%
When P04.00=1 (multi-dot V/F curve), you can
set the V/F curve through P04.03–P04.08.

The V/F curve is generally set according to the
load of the motor.
Note: V1 < V2 < V3, f1 < f2 < f3. Too high
voltage for low frequency will cause motor
overheat or damage and cause VFD overcurrent
stall or overcurrent protection.
Setting range of P04.03: 0.00Hz–P04.05
Setting range of P04.04, P04.06, P04.08: 0.0%–
110.0% (of the motor rated voltage)
Setting range of P04.05: P04.03–P04.07
Setting range of P04.07: P04.05–P02.02 (of the
motor rated frequency)
