6-10-6 Frequency Jump Function (n083 to n086)
• The frequency jump function prevents the Inverter from generating frequencies that make the
mechanical system resonate.
• The frequency jump function can be used effectively to set three dead bands of a frequency reference.

Set Values
• Set n083 through n085 for jump frequencies 1 through 3 to the central values of jumping frequencies.
• Values will be set in 0.01-Hz increments if the frequency is less than 100 Hz and 0.1-Hz increments if
the frequency is 100 Hz or over.
• These values must satisfy the following condition.
n083 y n084 y n085
• The value in n086 must be set for the jump width.
• This function is disabled with n086 set to 0.0.
• The operation of the Inverter within the dead bands is prohibited. While the Inverter is in acceleration
or deceleration control, however, the Inverter does not jump the bands but changes the frequency
smoothly.
