„ Connection Example and Time Chart
The following diagram and time chart show how to set up the control circuit terminal for a 9-step speed
sequence.

Setting Precautions
When setting analog inputs to step 1 to step 2, observe the following precautions.
• Step 1
When setting terminal A1’s analog input to step 2, 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 the analog input for terminal A2 to step 2, also set H3-09 to 2 (Auxiliary Frequency Refer-
ence 1). When setting d1-02 (Frequency Reference 2) to step 2, set H3-05 to 1F (do not use analog inputs).
• Step 3
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).
