12.6 Special Running Behaviors
12.6.1 Skip Frequency
This function is used to avoid the mechanical resonance of the motor by defini-
tion of skip frequencies.
Code Name Setting range Default Min. Attri.
E0.70 Skip frequency 1 0.00...[E0.09] Hz 0.00 0.01 Stop
E0.71 Skip frequency 2 0.00...[E0.09] Hz 0.00 0.01 Stop
E0.72 Skip frequency 3 0.00...[E0.09] Hz 0.00 0.01 Stop
E0.73 Skip frequency range 0.00...30.00 Hz 0.00 0.01 Stop
E0.74 Skip window acceleration factor 1...100 1 1 Stop
The setting ranges of the three skip frequencies are shown in the figure below:
Fig. 12-32: Skip frequency
Skip frequency points are defined by parameters E0.70...E0.72. Skip frequency
range or boundaries are defined by parameter E0.73 as listed below:
●
[Upper boundary frequency] = [Skip frequency] + [E0.73]/2
●
[Lower boundary frequency] = [Skip frequency] - [E0.73]/2
If the current 'Output frequency' is higher than the 'Upper boundary frequency',
and the target 'Setting frequency' is within the 'Skip frequency range', the actual
output frequency will be limited to 'Lower boundary frequency'.
If the current 'Output frequency' is lower than the 'Lower boundary frequency',
and the target 'Setting frequency' is within the 'Skip frequency range', the actual
output frequency will be limited to 'Upper boundary frequency'.
●
If [E0.73] = 0.00, 'Skip frequency' function is inactive.
●
Do NOT set E0.70, E0.71 and E0.72 overlapping or nesting in each
other.
