Using Multi-Step Speed Operation
With Varispeed-G7 series Drives, you can change the speed to a maximum of 17 steps, using 16 frequency ref-
erences, 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 speed references 1 to 3 and the jog reference selection in the
multi-function contact inputs.
Multi-function Contact Inputs (H1-01 to H1-10)
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 references 1 to 3 and the jog frequency selection. The follow-
ing table shows the possible combinations.
* Terminal S8's jog frequency selection is given priority over multi-step speed references.
