Using Multi-Step Speed Operation - YASKAWA Varispeed G7 Series Instruction Manual



Using Multi-Step Speed Operation

With Varispeed-G7 series Inverters, you can change the speed to a maximum of 17 steps, using 16 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 Constants
To switch frequency references, set multi-step speed references 1 to 3 and the jog reference selection in the
multi-function contact inputs. Setting examples are shown below.

Combination of Multi-Function References and Multi-Function Contact Inputs
You can change the selected frequency reference by combining the ON/OFF status of S5 to S9 (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.
