Setting Precautions
Refer to the following to set step 1 to step 3 to analog inputs.
• Step 1
When setting terminal A1's analog input to step 1, set b1-01 to 1, and when setting d1-01 (Frequency Ref-
erence 1) to step 1, set b1-01 to 0.
• Step 2
When setting terminal A3's analog input to step 2, set H3-05 to 2 (auxiliary frequency reference 1). When
setting d1-02 (Frequency Reference 2) to step 2, set H3-05 to 1F (Analog input not used).
• Step 3
When setting terminal A2's analog input to step 3, set H3-09 to 3 (auxiliary frequency reference 2). When
setting d1-03(Frequency Reference 3) to step 3, set H3-05 to 1F (Analog input not used).
When inputting 0 to 10 V to terminal A2’s analog input, set H3-08 to 0, and turn OFF DIP switch pin S1-2
on the control circuit terminal board. (Refer to page 2-33.)
