7. 3. 3
Input the current signal of 4(0) - 20 mAdc between the terminals [II]-[CC].
■ Setting example
The following shows an example of how to externally input the run commands to the digital input
terminals with a current input of 4 - 20 mAdc.
The frequency shall be 0 Hz for the minimum input of 4 mA, and 60 Hz for the maximum input of 20
mA.
• <CMOd: Run command select> = "0: Terminal"
• <FMOd: Frequency command select 1> = "3: Terminal II"
• <F216: II point 1 input value> = "20" (%)
• <F217: II point 1 frequency> = "0" (Hz)
4
• <F218: II point 2 input value> = "100" (%)
• <F219: II point 2 frequency> = "60" (Hz)
4
For the characteristics of input currents and output frequencies, set at two points of <F216> and
<F217>, and <F218> and <F219>. The reference for 100% of the input value is 20mA.
