(2)
Frequency lower limit: set the lower frequency limit for output in [Hz] unit. Limiting frequency
value should be in between starting frequency and maximum frequency.
(3)
Frequency jump 1~3: Set the center frequency values of jumping frequencies 1~3 in [
㎐
] unit.
(4) frequency jump width 1~3: Set the 1/2 widths of jumping frequencies in [
㎐
] unit.
[Reference 5]
Equipments themselves have the specific resonance frequencies. If inverter chooses
resonance frequency of installed motor as the rotating frequency of motor, the motor can
severely be damaged. So N5000 prevents the resonating phenomenon by jumping the
resonance frequency of the motor.
☞
Frequency jump: Center frequency for jumping (=resonance frequency)
☞
Frequency jump width: 1/2 frequency width of jumping width.
Relationship between frequency jump and output frequency
4.3.13 Group A Screen 5
‘Group A Screen 5’ screen panel comes out when DOWN (
) button in ‘Group A Screen 4’ screen
panel or UP (
) button in ‘Group A Screen 6’ screen panel is touched. PID(proportional–Integral–
Derivative) controlling functions are set in this panel.
