1.
Fn_26/27/28/29 will be effective only when Fn_11 = 1 or 2 ( frequency set by digital
operator r terminal analog frequency signal control)
2.
Fn_27 can be set as follows (curve 3) :
a: If signal is 1~ 5 V, Fn_27 will equal to the voltage of 0Hz divided by 5V
b: If signal is 4 ~ 20 mA, Fn_27 will equal to the current of 0Hz divided by 20 mA.
c: If signal is 0~ 10V, same method as above
3.
Setting of Fn_28: If signal is 0~ 20 mA, Fn_28 will equal to the current of Fn_06
divided by 20 mA.
Remark: Signals of VR on TM2 and Digital operator are 0~5V; Analog input terminal of
terminal block can accept 0~5 V / 0~10V/ 0~20 mA signals.
Remark: Fn_28 must be greater than Fn_27
