Wobble operation can be used in V/F and V/F+PG control mode to modulate the output frequency around the
reference frequency for use in winding application to create an evenly wound roll.
Refer to the figure 4.4.104 for the wobble operation and the related parameter settings.
Figure 4.4.104 Wobble operation and the related parameter setting
In wobble operation, one of multifunction digital inputs (03-00 to 03-07) is set to 37 (wobble operation) and the run
command is active. When the wobble operation is ready, the inverter output frequency reaches the center
frequency (19-00). The acceleration time to the center frequency is the original pre-set acceleration time (Tacc 1
to Tacc 4). When the wobble operation is closed or the run command is removed, the deceleration time used is
the original pre-set deceleration time (Tdec 1 to Tdec4).
