Description Of Specific Functions
V800 Series High Performance Closed-Loop Vector Inverter User Manual
F6.2.47 Preset frequency of
traverse
Setting range: 0.00~[F0.1.21]
Factory default:10.00
F6.2.48 Waiting time for preset
frequency
Setting range: 0.0~6000.0Sec.
Factory default: 0.0
Preset frequency is referred to the operation frequency before frequency inverter adopts swing frequency
operation or breaks away from operation frequency of swing frequency operation. Determine the operation
mode of preset frequency according to the instruction of swing frequency function.
When the selected swing frequency function is valid ([F6.2.46]＝_ _ _ 1), frequency inverter starts swing
frequency preset frequency after running, then runs the swing frequency operation status via the process of
preset frequency waiting time.
In case of the selected swing frequency function terminal available ([F6.2.46]＝_ _ _ 2), when swing
frequency operation input terminal is valid, frequency inverter runs the swing frequency operation status;
When it invalidates, frequency converter outputs preset frequency ([F6.2.47]), and the preset frequency
waiting time is unavailable.
F6.2.49 Swing frequency
amplitude
Setting range: 0.0~50.0%
Factory default: 10.0
Swing frequency amplitude is the ratio of swing frequency amplitude.
When it occurs to fixed swing frequency amplitude ([F6.2.46]＝_ 0 _ _), mathematics of practical swing
frequency amplitude is:
Practical swing frequency amplitude= [F6.2.49] × maximum frequency [F0.1.20]
When it occurs to changeable swing frequency amplitude ([F6.2.46]＝_ 1 _ _), mathematics of practical
swing frequency amplitude is:
Practical swing frequency amplitude= [F6.2.49] × (preset frequency of swing frequency center [F6.2.53] +
frequency set value F0.1.16)
F6.2.50 Sudden jump frequency
Setting range: 0.0~50.0%
Factory default: 10.0
Sudden jump frequency is the amplitude of frequency's fast descending after it reaches upper boundary in
swing frequency cycle, that is, the amplitude of frequency's fast ascending after it reaches lower boundary.
See in detail the Reference Diagram 7-50.
Practical sudden jump frequency = [F6.2.50] × practical swing frequency amplitude.
F6.2.51 Rise time of triangular
wave
Setting range: 0.0~1000.0Sec.
Factory default: 10.0
F6.2.52 Fall time of triangular
wave
Setting range: 0.0~1000.0Sec.
Factory default: 10.0
The parameter in this group is referred to acceleration and deceleration slope in the process of swing
frequency.
Triangular wave rising time is referred to the time spent from the lower boundary frequency to the upper
boundary frequency in swing frequency operation, that is, the acceleration time in the cycle of swing
frequency operation.
Triangular wave decreasing time is referred to the time spent from the upper boundary frequency to the lower
boundary frequency in swing frequency operation, that is, the deceleration time in the cycle of swing
frequency operation.
The sum of triangular wave rising time and decreasing time is the swing frequency operation cycle.
F6.2.53 Center frequency
setting of traverse
Setting range: 0.00~[F0.1.21]
Factory default: 10.00
Frequency setting in the center of the swing frequency is referred to the center value of frequency converter
output frequency in the process of swing frequency operation.
Center frequency of practical output = [F6.2.53] + F0.1.16 certain set frequency.
