Note:
1.(Fn_26) (Fn_27) (Fn_28) and (Fn_29) will only work with (Fn_11) set at 1 or 2 (Speed
Controlled by Keypad or TM 2)
2. (Fn_27) can be set as follows for (curve 3)
a: If the signal is 1~ 5 V, (Fn_27) will equal the voltage of 0 Hz divided by 5V,
i.e. 1/5*100%=20%
b: If the signal is 4 ~ 20 mA, (Fn_27) will equal the current of 0 Hz divided by 20 mA.
i.e. 4/20*100%=20%
c: If the signal is 0~ 10V, use the same method as above, i.e. 0/10*100%=0%
3. Setting up (Fn_28) If the signal is a 0~ 20 mA, (Fn_28) will equal to the current of (Fn_06)
divided by 20 mA. The (Fn_28) must be greater than (Fn_27)
Remarks:
Signals from a VR on TM2 or the Keypad are a 0~5V signal. The Analog input
terminal of the terminal block can accept a (0~5 V) (0~10V) (0~20 mA) signal.
