How can you limit the output frequency that the ATV18 will run at?

You can first limit the maximum frequency by going into the Level 2 parameter and setting the maximum frequency ( tFr ) down to minimum of 40hz. The high speed will not go above this value.

Then to further limit below this value you can set the HSP value in hertz in Level 1 parameter down to minimum of LSP hz value.
The unit will not try to run above HSP which is what the maximum speed reference corresponds to.
