5.1 Torque Boost (P.0, P.46) V/F
P.0 “Torque boost”
P.46 “The second torque boost”
● For an inverter controlled by the V/F mode, the starting torque is usually inadequate when starting
the motor because the output voltage of the inverter is inadequate. In this case, improve the output
voltage by setting up a proper torque boost (P.0) to obtain a better starting torque.

<Setting>
• If P.0=6% and P.19=220V, and output frequency of the inverter is 0.2Hz, the output voltage will be:
• If RT is ‘ON’, P.46 The Second Torque Boost will be valid.
Note: 1. A too large set value of P.0 may cause actions of the current protection of the inverter or the inverter will be
disabled for a smooth start.
2. The second function is valid only when P.44 is not equal to 9999.
3. RT in this paragraph is referred to as the multi-function control terminals. For selecting the function and
using the multi-function control terminal, please refer to P.80~P.84, P.86. For the wiring, please refer to
Section 3.5.6.
