Function of thousands digit of parameter P7.11 is to decide whether the former
running information be stored or not when the power supply is on after off; If the
storage is effective, the hundreds digit of parameter P7.11 will decide whether the first
startup runs from the wobbling presetting frequency or not; If the storage is disabled,
the first startup will run from the wobbling presetting frequency during each running
under power on. In addition, resetting to the wobbling frequency running status can be
realized by the multi-function terminal that is defined as Wobbling freq. status reset.
P7.14 Wobbling frequency width
Setting range
This parameter is the rate of wobbling frequency width.
When the fixed wobbling frequency is selected, the actual wobbling frequency width
is calculated as following:
Wobbling frequency width =P7.14 × upper limit frequency
When the variable wobbling frequency is selected, the actual wobbling frequency
width is calculated as following:
Wobbling frequency width =P7.14× (Wobbling frequency centre frequency basic
P7.18+P0.01 frequency setting)
P7.15 Skip frequency
Setting range
It is the rapidly degressive extent during wobbling frequency running, when the
frequency arrives at the wobbling upper frequency; on the contrary, when it arrives at
the wobbling lower frequency.
Actual skip frequency=P7.15× Wobbling frequency width value
P7.16 Wobbling frequency period
Setting range
This parameter is used for setting one time wobbling frequency period.
