6. Description of Parameters
- 155 -
Related function parameters are as follows:
Function Code Parameter Name Setting Range Default
Fb-00
Wobble setting mode 0: Relative to the frequency reference
1: Relative to the max. frequency
0
This function parameter selects base value of wobble amplitude.
Function Code Parameter Name Setting Range Default
Fb-01
Wobble amplitude 0.0% to 100.0% 0.0%
Fb-02
Wobble step 0.0% to 50.0% 0.0%
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 Setting Range Default
Fb-03
Wobble cycle 0.0s to 3000.0s 10.0s
Fb-04
Triangular wave rising
time coefcient
0.0% to 100.0% 50.0%
Fb-03: It species 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
coefcient, unit: s)
● Triangular wave falling time = Fb-03 (Wobble cycle) x (1 - Fb-04 Triangular wave rising time
coefcient, unit: s)
6.8.2 Fixed Length Control
The drive has the xed 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 Setting Range Default
Fb-05
Set length 0 to 65535 m 1000 m
Fb-06
Actual length 0 to 65535 m 0 m
Fb-07
Number of pulses per
meter
0.1 to 6553.5 100.0
In the following gure, 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".
