Parameters
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.

NOTES During acceleration/deceleration, the running 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 fre-
quency 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.)
