Related function parameters are as follows:
Function Code Parameter Name
Fb-00 Wobble setting mode
This function parameter selects base value of wobble amplitude.
Function Code Parameter Name
Fb-01 Wobble amplitude
Fb-02 Wobble step
Fb-01 and Fb-02: These function parameters set wobble amplitude and wobble step.
●
When Fb-00 = 0, Aw (wobble amplitude) = F0-07 (Frequency source superposition selection)
x Fb-01.
●
When Fb-00 = 1, Aw (wobble amplitude) = F0-10 (Max. frequency) x Fb-01.
Wobble step frequency = Aw (wobble amplitude) x Fb-02 (Wobble step). The wobble running
frequency must be within frequency upper limit and frequency lower limit.
Function Code Parameter Name
Fb-03 Wobble cycle
Fb-04 Triangular wave rising
time coefficient
Fb-03: It specifies time of a complete wobble cycle.
Fb-04: It is percentage of triangular wave rising time to Fb-03 (Wobble cycle).
●
Triangular wave rising time = Fb-03 (Wobble cycle) x FB-04 (Triangular wave rising time
coefficient, unit: s)
●
Triangular wave falling time = Fb-03 (Wobble cycle) x (1 - Fb-04 Triangular wave rising time
coefficient, unit: s)
6.8.2 Fixed Length Control
The drive has the fixed length control function. The length pulses can only be sampled by DI5.
Set DI5 for function 27 "Length signal pulses count".
Function Code Parameter Name
Fb-05 Set length
Actual length
Fb-06
Fb-07 Number of pulses per
meter
In the following figure, actual length is a monitored value.
Actual length (Fb-06) = Number of pulses sampled by DI is divided by Fb-07 (Number of pulses
each meter).
When actual length reaches the value set in Fb-05, digital output terminal set for function 10
"Length reached" becomes on. Length reset can be implemented via DI terminal set for function
28 "Length reset".
Setting Range
0: Relative to the frequency reference
1: Relative to the max. frequency
