NOTE: Setting conditions
0 Hz or upper limit ≥ lower limit
When 0 Hz is set, the limiters will not operate.
Set the limits of frequency setting within the start frequency adjustment range and
maximum frequency setting range. When a value beyond the limits is inputted from the operator,
it will not be stored. Even if a value beyond the limits is inputted as external analog input, the set
value will not be changed.

frequency
setting 1
To avoid a resonance with the load, the frequencies at up to 3 points can be jumped. The setting
order and the execution order may be changed.
The frequency equivalent to the jump frequency setting width (± 0.5 Hz) (Note 1) cannot be set as
a jump frequency.
