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.
When the 5-00=6, it is similar to decrease progressively frequency control mode in the main winding that in
the range of the setting length the extra-feeding frequency decreases progressively with a constant speed.
In the function of the progressive decrease of the extra-feeding frequency the parameter 5-09 is the
Stopping Frequency and the 5-10 is the Starting Frequency. The Extra-feeding frequency will decrease
progressively from 5-10 to 5-09. When the winding adopts the constant velocity, and extra-feeding adopts
the frequency increase or decrease progressively, must pay attention to that the double-length coefficient
should be consistent with the unit of 1-05 (namely the representative units of length should be same each
other).

2, the setting parameters of the 5-11 and 5-12 are valid. After the winding and the
extra-feeding come into stable operation, when the winding length increases the setting value of 5-11 once,
the extra-feeding will base on the setting value of 5-01, to increase the setting value of 5-12. As an example,
if 5-01=500m/min, 5-11=80m and 5-12=4 m/min, then in operation, when the velocity of the extra-feeding
achieves 500m/min, then to begin the accumulation of the winding length and the extra-feeding velocity
will increase 4m/min while the actual value of winding length increase 80m once.
