Wobble Frequency Function Parameters - Savch S900 Series User Manual

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.
Pattern operation shall run simultaneously with wobble frequency, and wobble frequency shall be unavailable in
switching of pattern operation period. Wobble frequency shall start after pattern operation setting is reached in
accordance with accel/decel setting in pattern operation period; and decelerating to machine stop shall be according
to deceleration time in pattern operation step.
