During the process of restoring the Factory Values, the “dT...” is displayed to express the data are in transferring: “data transferring”.
  • Page 27 Yatai Inverter YTB-S-LT User’s Manual beginning time, and then PI control the velocity. For instance: if 1-04 is set up to 40.0 mm，1-02 is set up to 300m/min, then if 1 Hz is estimated according to 30 R/min, the target frequency for beginning operating is 300*1000／40.0／30／3.14＝79.62Hz.
  • Page 28 Yatai Inverter YTB-S-LT User’s Manual of the converter at the beginning of spinning (Spindle Empty). Along with the changing of the spinning length, the frequency is also decreasing as well. If the machine halts without full yarn, then the target frequency at operation of the next time is just the frequency at the time of machine halt.
  • Page 29 Yatai Inverter YTB-S-LT User’s Manual operating will be according to a general constant frequency and together with the diameter increasing of yarn bobbin, the velocity of the yarn also gradually increases as well. However the Figure B adopts the operating mode of increasing progressively from the Stopping Frequency to the Starting Frequency, it can increase the velocity of the yarn effectively and make the efficiency of spinning able to be improved obviously.
  • Page 30 Yatai Inverter YTB-S-LT User’s Manual frequency, the operation process is shown in the Figure below. Setting up the 2-03 and 2-04 must ensure (2-03)－(2-04)>0.50Hz, otherwise the lowest operating frequency is 0.50Hz and bring about the cycle period inaccurate. While setting up the parameters, the acceleration and deceleration time are easy to be too long.
  • Page 31 Yatai Inverter YTB-S-LT User’s Manual Function Code 4 District 4-00 Delay Detect the Yarn Factory Value：3.0 broken Time Setting Range：1.0～20.0 S Because at the beginning of the converter’s operation the yarn is still up on the spindle, the sensor for yarn broken would account the yarn has been break, this parameter must be set up to make the converter not treat the signal of yarn broken in this period of time.
  • Page 32 Yatai Inverter YTB-S-LT User’s Manual 4-03 is set up to “0”, then when machine halt or yarn broken, between OUT1 and 12V there are several seconds output; if 4-03 is set up to “1”, there are several seconds output when yarn is full. The output time is set up by 4-04.
  • Page 33 Yatai Inverter YTB-S-LT User’s Manual can adjust it according to his requirements. 4-11 Protection Value of PI Setting Range：20～100 m/min Factory Value：50 Control The Function Code 4-11 means that when the difference between the target velocity and the actual velocity exceeds the setting value of 4-11, the converter will jump to the protection of Err2.

  • Page 37 Yatai Inverter YTB-S-LT User’s Manual increasing frequency. It is commonly applicable to the situation of smaller textile yarn bobbin and then able to increase the spinning velocity in the allowable range of the extra-feeding velocity. As an example, if the setting length is 1000 m, 5-09=50Hz and 5-10=60Hz, then while the winding length increases from 0m to 1000m the operating frequency of the extra-feeding increases from 5-09 to 5-10.
  • Page 38 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.
