■ Setting method
Set a frequency command for an analog input amount at two points.
For the corresponding parameters of each terminal and the setting method, refer to the following.
As default setting, the range between the minimum and maximum input amounts is set to 0 to 50.0/
60.0 Hz for main analog signal of the terminals. For example, the terminal [RR] is set to 0 to 50.0/
60.0 Hz at 0-10 V.
• For the terminal [RX], select the voltage for <F107: Terminal RX input voltage select>.
• For the terminal [AI4], select the analog signal for <F148: Terminal AI4 input select>. For the
terminal [AI5], select the analog signal for <F149: Terminal AI5 input select>. The terminals [AI4]
and [AI5] are optional.
• If noise disturbs stable operation, increase the value for <F209: Analog input filter>. Doing so
eliminates the noise of the frequency setting circuit.
• Do not set the same value for point 1 and point 2. Failure to do so displays "Err1".
For details on the analog signal setting, refer to [7. 3].
1) For setting the voltage input of 0-10 V (terminals [RR]), refer to the following
figure.
2) For setting current input of 4-20 mA (terminal [II]), refer to the following figure.
