Yatai Inverter YTB-S-LT User’s Manual
When the 5-00
＝
4, this parameter is valid. The operating velocity of the extra-feeding motor is proportional
to the velocity of the winding motor, so for various yarn the user should set the different and appropriate
proportional coefficient to meet the sufficient extra-feeding amount. For instance, in this mode firstly need
to preset the velocity of the extra-feeding motor, otherwise would cause the yarn broken. If the velocity of
winding is predict 500m/min after completing the start-up process and the Tracking Coefficient 5-13=1.20,
then the setting value of 5-01=500*1.2
＝
600m/min. In order to make the pressure roll reflect the velocity
better, it is needed to begin its control after delay automatically a period of time (about 10 seconds).

This parameter is used to increase the initial operating frequency, convenient for the start-up of the
Extra-feeding motor. It is applicable to the situation with d

When needing the braking, such three parameters are valid. The Braking Voltage and the Braking time are
not suitable too large so as to avoid damaging the extra-feeding motor.
