7-3 Description of Functions
Auxiliary function
F1301 1st jump bottom frequency
F1302 1st jump top frequency
F1303 2nd jump bottom frequency
F1304 2nd jump top frequency
F1305 3rd jump bottom frequency
F1306 3rd jump top frequency
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.

●
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.
3) If the target frequency is changed to 50Hz from 60Hz: the inverter continues to operate at 52Hz.
Example 2) F1301=39Hz, F1302=43Hz, F1303=41Hz and F1304=46Hz.
Jump frequencies are combined, and the range from 39-46Hz is skipped.
F1301=48Hz F1302=52Hz

●
The 1st, 2nd and 3rd jump frequencies can be set independently, for example, 2nd jump frequency> 1st jump
frequency> 3rd jump frequency.
