 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.
• When the set frequency decreases and falls within the jump range, the upper limit of the jump range is the set frequency.
When the set frequency increases and falls within the jump range, the lower limit of the jump range is the set frequency.

NOTE
• During acceleration/deceleration, the frequency within the set area is valid.
• If the setting ranges of individual groups (1A and 1B, 2A and 2B, 3A and 3B) overlap, write disable error (Er1) will occur.
• Setting Pr.552 = "0" disables frequency jumps.
• If a jump frequency that exceeds Pr.1 (Pr.18) Maximum frequency is set for the 3-point jump, the maximum frequency
setting is the set frequency. If the set frequency is less than the jump frequency Pr.2 Minimum frequency, the jump
frequency is the set frequency. (The set frequency can be equal to or lower than the frequency lower limit.) Example with
