Setting Precautions
When setting analog inputs to step 1 to step 3, observe the following precautions.
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.
When setting terminal A2's analog input to step 2, set H3-09 to 2 (auxiliary frequency reference). When
•
setting d1-02 (Frequency Reference 2) to step 2, set H3-09 to 1F (do not use analog inputs).
When setting terminal A3's analog input to step 3, set H3-05 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).
