Basic parameter group 01
PARAMETER DESCRIPTION 83
5.2.5 Starting frequency
When the motor starts up, the instantaneous output frequency of the inverter is called “starting frequency”.
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
In V/F control, you can choose the best output characteristics for different applications and load.
For constant torque loads (conveyor belt,etc.)
For variable torque loads (fans and pumps, etc.)
Special two-point V/F curve
V/F complete detached 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.
If RT is “on”, 01-24
(P.46)
“the second torque boost” is valid.
