A Wobble Frequency Function Parameters
Wobble function shall be applicable to industries such as textile and chemical fiber, and circumstances
which needs traversing or coiling. Diagram below shows typical work diagram:

Wobble process shall be following for general: Firstly accelerate in accordance with acceleration time to
preset frequency A-02, and wait for a time of A3, then wobble centering frequency (A-04, A-05)
according to accel/decel time shall be realized. After that, it shall run in cycle in set wobble amplitude
(A-06, A-07), wobble frequency hopping A-08, wobble cycle A-09 and triangle wave rising frequency
A-10. It shall stop in accordance with deceleration time when a STOP command is received.
Also attention shall be paid that, wobble frequency shall be cancelled automatically in jog running or
closed loop running.
PLC shall run simultaneously with wobble frequency, and wobble frequency shall be unavailable in
switching of Plc period. Wobble frequency shall start after PLC setting is reached in accordance with
accel/decel setting in Plc period; and decelerating to machine stop shall be according to deceleration
time in PLC step.

Wobble Frequency Function selection
Factory setting
d 0
Setting range
d 0
Not using wobble function
d 1
Using wobble function
This parameter is to determine using wobble frequency function or not.
A-01
Wobble Frequency input mode
Factory setting
d 0
Setting range
d 0
Input automatically (A-03)
d 1
Manually controlled by external terminals.
This parameter is to set input mode of wobble frequency:
When it is set to 0, it shall be input automatically. In this case, it shall firstly run for a period (A-03) in
wobble frequency preset frequency (A-02) after starting, and then wobble frequency shall be
realized automatically.
When it is set to 1, it shall be controlled manually by external terminals. Which means that wobble
frequency shall be realized when multifunction terminal (Function 27 is for wobble frequency input)
available; while wobble frequency shall not exist when terminal unavailable, with running frequency
kept at wobble frequency preset frequency A-02.
