final specified value of VFD frequency.
2: A-K*B
Principle frequency A minus auxiliary frequency B multiplied by weight coefficient K, the result is the final specified value
of VFD frequency.
3: |A-K*B|
Principle frequency A, auxiliary frequency B multiplied by weight coefficient K, the absolute value of their difference is
the final specified value of VFD frequency.
4: MAX (A, K*B)
Principle frequency A, auxiliary frequency B multiplied by weight coefficient K, the higher value of these two is the final
specified value of VFD frequency.
5: MIN (A, K*B)
Principle frequency A, auxiliary frequency B multiplied by weight coefficient K, the lower value of these two is the final
specified value of VFD frequency.
6: switch from A to K*B
This function is used together with number 29 item of F7 group parameter X1~X8. When F0.09=6, and X terminal
function is 29, the X terminal is valid, frequency given source switch from A to K*B; if X terminal is invalid, the frequency
source returns to A.
7: switch between A and (A+K*B)
This function is used together with number 30 item of F7 group parameter X1~X8. When F0.09=7, and X terminal
function is 30, the X terminal is valid, frequency given source switch from A to (A+K*B); if X terminal is invalid, the
frequency source returns to A.
8: switch between A and (A-K*B)
This function is used together with number 31 item of F7 group parameter X1~X8. When F0.09=8, and X terminal is 31, X
terminal is valid, frequency given source switch from A to (A-K*B); if X terminal is invalid, the frequency source returns to
A.
Notice
:
The given value of frequency is still restricted by start frequency and higher and lower limit frequency, and being
