Values, that is to say, if choosing its value as 1, then pushing the setting key can make all the parameters
restore to their Factory Values. During the process of restoring the Factory Values, the “dT...” is displayed
to express the data are in transferring: “data transferring”.

Parameter 1-02 is used to set the target velocity, namely the reference velocity of PI control; the parameters
1-00 and 1-01 are mainly used to control the response speed and control amplitude. If the user requires the
rapid response for the change, he can set the parameter 1-01 to a smaller value; otherwise he should set it
larger. If the user requires the extent by control every time with larger than the last one, he can set the
parameter 1-00 as a slight large value (but inappropriate too large, if that it is easy to produce oscillation),
else should set it smaller. Users can set these two parameters according to the actual situation, until to its
suitable state.
1-03 Roller Diameter
Setting Range:10.0
～
50.0 mm
Factory Value:22.0
This parameter is used to count the length of the spinning yarn and the velocity. By the sensor mounted on
the converter, sampling the pulses which are passing through the OP2 Port on the terminal and sending to
the CPU, then make the count of the length. As an instance: if 1-03 is set to 22.0 mm, 10 pulses every
minute then the velocity is 22.0*3.14*60*10/1000=41.1 m/min. Every 14.5 pulses (1000
／
22.0/3.14=14.5)
the length is increased by 1m.

This parameter is valid only for the empty spindle. It is mainly set up for estimating the operating velocity
in the empty spindle state to make it convenient to operate immediately with near the setting velocity at the
