172 Chapter 6 Parameter description
FA.02 Jitter Time Range: 550ms5ms
FA.03 Wobble freq. rising time Range: 0.1999.9s5.0s
FA.04 Wobble freq. dropping time Range: 0.1999.9s5.0s
Wobble frequency amplitude: The running amplitude around setup
frequency.
Wobble frequency rising time: The time takes from the peak base
(lowest frequency in the swing) to the peak height (highest frequency in the
swing).
Wobble frequency dropping time: The time takes from the peak height
(highest frequency in the swing) to peak base (lowest frequency in the
swing).
FA.05 Amplitude setting mode Range: 010
This parameter is used to select the benchmark quantity of the swing
amplitude.
0: Relative to the central frequency
It is variable swing amplitude system. The swing amplitude varies with
the change of central frequency (setup frequency).
1: Relative to the maximum frequency
It is fixed swing amplitude system. The swing amplitude is fixed.

FB.00 Preset length Range: 0~65530 0
FB.01 Actual length Range: 0~65530 0
FB.02 Pulse number per unit Range: 0.1~6553.0100.0
The preset length (PB.00), actual length (PB.01) and number of pulse
per-unit (FB.02) are mainly used for fixed-length control. The length is
calculated via the pulse signal input by the discrete input terminal, which
