⋅Adjustable 5 points V/F will not function under simple magnetic flux vector control.
⋅When Pr. 19 Base frequency voltage = "8888" or "9999", Pr. 71 cannot be set to "2". To set Pr. 71 to "2", set the rated voltage value to Pr. 19
⋅When the frequency values of the points are the same, a write
inhibit error ( ) occurs.
⋅Set the points (frequencies, voltages) of Pr. 100 to Pr. 109 within the ranges of Pr. 3 Base frequency and Pr. 19 Base frequency voltage .
⋅When “2” is set in Pr. 71, Pr. 47 Second V/F (base frequency) will not function.
⋅When “2” is set in Pr. 71, thermal characteristic of the electronic thermal relay function changes to thermal characteristics of a standard motor.
