6.1 Schedule of Function Parameters
whether to save previous operation info for wobble start or not when the power is
switched on after power failure. If the store is valid, then the hundreds digit of
parameter F7.11 decides whether the first start will be started at the wobble preset
frequency. If there is a decision not to save the info, then the first operation will be
started at the wobble preset frequency once the power is switched on. Besides, the
wobble status will be reset by multi-function terminals defined with wobble operation
status reset.
F7.14 Wobble amplitude range Setting range: 0.0~50.0% Default value: 10.0%
This parameter refers to the percentage of wobble range. If fixed wobble range is
selected, then the actual wobble value will follow the formula below:
Wobble range=F7.14
upper limit frequency
If variable wobble range is selected, then the actual wobble range will follow the
formula below:
Wobble range=F7.14
defined frequency setting (wobble center frequency reference
F7.18 + F0.01)
F7.15 Kick frequency Setting range: 0.0~50.0% Default value: 0.0%
This parameter refers to the range of quick fall after the frequency reaches the upper
limit during the course of wobbulation, or the range of quick rise after the frequency
reached the lower limit. The formula is shown below:
Actual trip frequency = F7.15
wobble range
F7.16 Wobble period Setting range: 0.1~3600.0s Default value: 10.0s
This parameter is used to set the period for wobble operation.
F7.17 Time for triangle wave rise Setting range: 0.0~100.0% Default value: 50.0%
This parameter defines the operation time for wobbulation from the lower limit to the
upper limit, which is also the acceleration time in a period of wobble operation. Its
formula is shown below:
Actual time for triangle wave rise =F7.17
wobble period
It is sure that the difference of time between wobble period and triangle wave rise is
the time of fall for triangle wave.
F7.18 Wobble center frequency reference Setting range: 0.00~upper limit frequency
Default value: 10.00Hz
This parameter refers to the reference value of wobble center for inverter's output
frequency when there is a wobble operation.
The actual wobble center is accumulated value of this parameter value and the
setting frequency decided by external frequency setting path F0.01. Its formula is
shown below:
Wobble center frequency=F7.18+F0.01 (given path setting frequency)
TIP
Wobble operation frequency is limited by the upper or lower
limit frequency. Improper setting may cause abnormal wobble
operation.
