Wobble function: the process of forming spindle is superimposed by two independent movements,
including constant-speed rotation movement and reciprocating movement. Superimposed by these two
independent movements, yarn will form a rhombic net track. If speed of these two movements is
constant, bumps will be formed at the intersection of yarns. To disorganize the intersection of each layer,
speed of reciprocating movement shall be changed constantly. Wobble function is specially designed for
winding yarns; it ensures that the yarns are wound around the spindle smoothly and evenly.
Wobble function is only valid for V/F control. It becomes invalid automatically in vector control, jog and
PID closed-loop operation.
The typical wobble operation is shown in the diagram below.

Run command
When F9-00=1, the inverter first accelerates to F9-02, waits for a period of time (F9-03)(or waits until
the digital input 53 becomes valid if F9-00=2), and then reaches the center frequency. After that, it
begins the wobble operation according to the settings of F9-04~F9-08 and keeps running until receiving
the stop command.
The source of the center frequency is the reference frequency for common operation, multi-speed
operation and PLC operation.
F9-04 should not set too high. That will cause motor overheating. F9-04 is normally set to 0.5~2Hz.
F9-05 is use to to overcome the actual speed lag caused by the inertia. It is only used when there is a
relatively large inertia of the grooved drum.
F9-06 sets the time the sudden jump frequency spends.
F9-07 sets the time for a complete wobble cycle.
F9-08 sets the time for the rising edge. Actual rising time=wobble peroid×rising time. Actual falling
time=wobble period×(1-rising time).
