Basic parameter group 01
PARAMETER DESCRIPTION 106
Torque boost

If 01-10(P.0)=6% and 01-04(P.4)=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 setting value of 01-10(P.0) is too high, the overcurrent protection function of the inverter will be activated
and the inverter cannot be operated due to the protection.
2. Please refer to Section 5.2.10 Second function.
3. RT mentioned in this section is the function name of the “multi-function digital input terminal”. Please refer to
03-00~03-09(P.80~P.84,P.86,P.126~P.128,P.550),03-25~03-30(P.551~P.556), 03-33~03-38(P.559~P.564);
Please refer to section 3.7 for wiring
5.2.5 Starting frequency

When the motor starts up, the instantaneous output frequency of the inverter is called “starting frequency”.
Parameter Name Default Setting Range Content
01-11
P.13
Starting frequency 0.50Hz 0～60.00Hz Set the frequency when the start signal is ON
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).

5.2.6 Load pattern selection
V/F

In V/F control, you can choose the best output characteristics for different applications and load.
Parameter Name Default Setting Range Content
01-12
P.14
Load pattern selection 0
0 For constant torque loads (conveyor belt,etc.)
1 For variable torque loads (fans and pumps, etc.)
2～3 For Lifting loads
4 Multipoint V/F curve
5～13 Special two-point V/F curve
14 V/F complete detached mode
15 V/F semidetached mode
Load pattern selection

When 01-12(P.14)＝4, suppose that 01-04(P.19)=220V, 01-26(P.98)=5Hz, 01-27(P.99)=10%, when the inverter is
running at 5Hz, the output voltage equals to 01-04(P.19)×01-27(P.99)＝220V×10%＝22V.
