5.2.4 Torque boost V/F

For an inverter controlled by V/F mode, when the motor starts up, the starting torque is usually insufficient since
the output voltage of the inverter is low. In this case, the output voltage can be elevated by setting the torque boost
(01-10) properly, and thus getting a better starting torque.

If 01-10(P.0)=6% and 01-04(P.19)=220V,and when output frequency of the inverter is 0.2Hz, the output voltage is:

If RT is “on,” “the second torque boost” on 01-24(P.46) is valid (Note 2).
Note: 1. If the set value of 01-10(P.0) is too high, it will activate over current protection or fail to start.
2. Please refer to Section 5.2.10 for the second torque boost.
3. RT mentioned in this section is the function name of the “multi-function digital input terminal”. Please refer to
03-00(P.83), 03-01(P.84), 03-03(P.80), 03-04(P.81)；for function selection of the multi-function digital input
terminal. For related wiring, please refer to Section 3.7.
5.2.5 Starting frequency

When the motor starts up, the instantaneous output frequency of the inverter is called “starting frequency”.


If target frequency of inverter is lower than 01-11(P.13) value, the motor will not run. When given the start signal to
motor, the output frequency will go up from the value of 01-11(P.13).
