• Use this function to add or subtract the value set in the Frequency Addition Amount Setting (A145) to
the selected frequency reference value.

The value set in A145 will be added or subtracted when the ADD terminal is ON.
• If the +/– sign in front of the frequency reference changes (from “–” to “+” or “+” to “–”) as a
result of operation, the rotation direction of the motor will be reversed.
• When the PID function is used, this function is enabled for the PID target value. (Note that
A145 is displayed in % (in increments of 0.01%).)
