Default
value
frequency reaches upper/lower limit
Tens:
0: The same with the main reference
direction
1: Contrary to the main reference
direction
Hundreds:
0: Limit as per the max. frequency
1: Limit as per A frequency
Thousands:
0: A+B frequency, acceleration
/deceleration of main reference A
frequency source buffering is invalid
1: A+B frequency, acceleration/
deceleration of main reference A
frequency source buffering is valid,
acceleration/deceleration is determined
by P08.04 (acceleration time 4).

5.5.16 Run at wobbling frequency
Wobbling frequency is mainly applied in cases where transverse movement and winding functions are
needed like textile and chemical fiber industries. The typical working process is shown as below.
