Setting Precautions
When setting analog inputs to speed 1 and speed 2, observe the following precautions.
• When setting terminal A1's analog input to speed 1, set b1-01 to 1, and when setting d1-01 (Frequency
Reference 1) to speed 1, set b1-01 to 0.
When setting terminal A2's analog input to speed 2, set H3-09 to 2 (auxiliary frequency reference). When
•
setting d1-02 (Frequency Reference 2) to speed 2, set H3-09 to 1F (do not use analog inputs).
