• When RUN Command Selection (A002) is set to 02 (Digital Operator)
Use the frequency jump function to avoid the resonant point of the load machine during operation.
• In the Jump Frequency 1 to 3 (A063/A065/A067), set the center of the jump-target frequency range.
• In the Jump Frequency Width 1 to 3 (A064/A066/A068) set 1/2 of the width of the jump-target
frequency range.
• When a jump frequency is set, the output frequency is the upper/lower-limit frequency of the set jump
frequency range, avoiding frequencies within that range.
• The output frequency changes continuously according to the acceleration/deceleration time settings
during acceleration/deceleration.
• You can set up to three jump frequency ranges.
