Setting Precautions
•
When inputting a current signal to terminal A2, turn ON pin 2 on DIP switch S1 (factory setting: ON).
•
The parameter H3-08 has to be set to 2 (4 - 20 mA input).
•
If using terminal A2 to input the master speed reference and terminal A1 to input the auxiliary frequency
reference, set H3-13 (Terminal A1/A2 Switching) to 1.
Using Multi-Step Speed Operation
With SYSDRIVE PV series Inverters, you can change the speed to a maximum of 5 steps, using 4 frequency
references and one jog frequency reference.
The following example of a multi-function input terminal function shows a 9-step operation using multi-step
references 1 to 3 and jog frequency selection functions.
Related Parameters
To switch frequency references, set multi-step references 1 to 3 and the jog reference selection in the multi-
function contact inputs.
Multi-function Contact Inputs (H1-01 to H1-05)
Combining Multi-Function References and Multi-Function Contact Inputs
You can change the selected frequency reference by combining the ON/OFF status of S4 to S7 (multi-function
contact input terminals) to set multi-step speed commands 1 to 3 and the jog frequency selection. The follow-
ing table shows the possible combinations.
* Terminal S7's jog frequency selection is given priority over multi-step speed commands.
Setting Precautions
When setting analog inputs to step 1 and step 2, 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).
