It is used to clear the diaeter calculate error at start. Right setting can prevent the calculate error at beginning of
winding.

traction roller speed by the photoelectric switch frequency, traction roller diameter and pulse per cycle. The formula is:
Traction linear speed=PUL* traction roller diameter

Note: While using linear calculate in winding, it must gain right traction linear speed.The normal way is sending
output frequency of the inverter who drives traction motor to winding inverter to gain run frequency of traction.
F9.26
Max linear speed
Max linear speed of traction. While the linear resource is analog input, the analog input max value and max linear speed
are linear corresponding relationship.

diameter calculate
Set the lowest linear speed where begin to calculate roll diameter. While inverter detect the linear speed is lower than
this value, inverter stop calculate. Right setting can prevent error at low speed. While setting linear calculate, this
parameter and the end frequency both are valid. The bigger value is the lowest value where stop calculate.

While [F9.25] Linear input resource is 0: F9.28/F9.29 terminal selection. It can select linear speed selection terminal
and define any terminals, details see [F2.00-F2.07] . Set traction linear speed by terminal switch can bring two group
