Using Multi-Step Speed Operation

With SYSDRIVE RV series Inverters, you can change the speed to a maximum of 17 steps, using 16 fre-
quency 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.
nRelated Parameters
To switch frequency references, set multi-step references 1 to 3 and the jog reference selection in the multi-
function contact inputs.
