For the inverter-driven motor, resonance generated in the co-ordination between output frequency (speed) and the mechanical system
produce larger vibration and noise, and the power frequency hopping sometimes cause the change in output voltage. In this case, the
frequency which generates mechanical vibration and voltage change will be jumped during operation.

F1306 3rd jump top frequency
● Three different frequencies to skip can be specified.
● The frequency jumps between the top frequency and bottom frequency set by F1301-F1306. However, no jump occurs during
acceleration/deceleration.
Example 1) F1301=48Hz and F1302=52Hz.
1) If the target frequency is set to 51Hz: the inverter continues to operate at 48Hz.
2) If the target frequency is set to 53Hz: normal acceleration skips 48-52Hz and reaches 53Hz at which the inverter continues to
operate.
Example 2) F1301=39Hz, F1302=43Hz, F1303=41Hz and F1304=46Hz.
Jump frequencies are combined, and the range from 39-46Hz is skipped.

● The 1st, 2nd and 3rd jump frequencies can be set independently, for example, 2nd jump frequency> 1st jump frequency> 3rd
jump frequency.
● The top value and the bottom value of a jump frequency can not be reversely set. Therefore, when setting the top value or the
bottom value, set the values in the correct order so that the top and bottom values are not reversed. (Because in the initial settings,
both the top and bottom values are specified as 0, setting the bottom value first will cause an error, such setting is prohibited.)
● When the upper frequency limit (F1007) or the lower frequency limit (F1008) is set within the jump frequency band, the
frequency will jump within the range of the upper frequency limit and lower frequency limit.
● Setting a jump frequency band that includes both the upper frequency limit (F1007) or highest frequency and the lower frequency
limit (F1008) is prohibited for safety reasons.
