 3-point frequency jump (Pr.31 to Pr.36)
• Up to three areas may be set, with the jump frequencies set to either the top or bottom point of each area.
• The settings of frequency jumps 1A, 2A, 3A are jump points, and operation is performed at these frequencies in the jump
areas.

Example 1) To fix the frequency to 30 Hz in the range of 30 Hz to 35 Hz, set 35 Hz in Pr.34 and 30 Hz in Pr.33.
Pr.34: 35 Hz
Pr.33: 30 Hz
Example 2) To jump the frequency to 35 Hz in the range of 30 Hz to 35 Hz, set 35 Hz in Pr.33 and 30 Hz in Pr.34.
Pr.33: 35 Hz
Pr.34: 30 Hz
 6-point frequency jump (Pr.552)
• A total of six jump areas can be set by setting the common jump range for the frequencies set in Pr.31 to Pr.36.
• When frequency jump ranges overlap, the lower limit of the lower jump range and the upper limit of the upper jump range
are used.
