Amplitude of swing frequency
Amplitude of the jump frequency
This parameter is used to determine the amplitude of the swing frequency and the jump
frequency.
The swing frequency is limited by the upper frequency limit and the lower frequency limit.
Concerning the middle frequency (Pb.00 = 0), the actual AW amplitude of the swing is the
result of the calculation the value of P0.03 (frequency source selection) multiplied by
Pb.01. Compared to the maximum frequency (Pb.00 = 1), the actual AW amplitude of the
swing is the result of P0.12 (maximum frequency) multiplied by Pb.01. Jump Frequency =
Swing amplitude AW x Pb.02 (Jump frequency amplitude). With respect to the mean
frequency (Pb.00 = 0), the jump frequency is a variable value. As for the maximum
frequency (Pb.00 = 1), the jump frequency is a fixed value.
Frequency of the swing is limited by the upper and lower frequency limits.
Time coefficient of triangle wave rise
Swing frequency cycle: the time of a complete swing frequency cycle.
Pb.04 specifies the time percentage of triangular wave rising time to Pb.03 (Swing
frequency cycle).
Triangular wave rising time = Pb.03 (Swing frequency cycle) x Pb.04 (Triangular wave rising
time coefficient, unit: s).
Triangular wave falling time = Pb.03 (Swing frequency cycle) x (1- Pb.04 Triangular wave
rising time coefficient. unit: s).
Number of pulses per meter
Previous parameters are used to control fixed lengths. Length information is gathered
through multifunctional digital inputs. The actual length Pb.06 is calculated by dividing the
number of pulses registered via input S by Pb.07 (pulse per meter).
