Traverse frequency function is suitable to industries such as textile, fiber and so on, and t o applications
which require traversing and winding functions.

the amplitude of traverse is set by F4.07 . When F4.07 is set to be 0, i.e. traverse range is 0, the traverse

Traverse frequency range: traverse operation frequency limits by upper and lower limit frequency.
Traverse range relative to the center frequency: amplitude of traverseAW = CF × AW range F4.07
Kick frequency = amplitude of traverseAW × Kick Frequency Range F4.08. I.e. the kick frequency is
the value relative to amplitude of traverse at traverse-frequency operation.
Traverse frequency rising time: the time required to rise from the lowest traverse frequency to the
highest traverse frequency.
Traverse frequency fall time: the time required to fall from the highest traverse frequency to the lowest
traverse frequency.
