micro-puling machine, the impact will lead to wire disconnection. Therefore, the
smoothly start-up disposal is needed. The method is as follows:
Start up acceleration deceleration time (acceleration deceleration time2)and
smoothly switch to normal work acceleration deceleration time (acceleration
deceleration time 1). Start up acceleration deceleration time is:
T

To fine-drawing machine and micro-puling machine:
F2.39=10000ms=10.000s,T
UP2
=150.0s，T
DN2
=150.0s，T
UP1
=2.0s，T
DN1
=2.0s.
To big and medium type drawing machine, we can reduce smoothly start-up
time of wire retracting machine:
F2.39=2000ms=2.000s,T
UP2
=150.0s,T
DN2
=150.0s，T
UP1
=2.0s，T
DN1
=2.0s.
2.1.7 Volume diameter automatically calculate time interval
Along with the growth of wire retracting volume diameter, the output frequency
of its needs to be constantly reduced. EDS1100 Series inverter has special volume
calculation function interiorly, it can calculate present volume diameter
dynamically in real time, in order to reach the best wire retracting effect. The time
interval of automatically calculation is F2.21，and the unit is MS.(millisecond)
To ensure the accuracy of volume diameter calculation and the stability of wire
retracting machine sway bar, we usually set:
F2.21=200~3200ms=0.200~3.200s
2.1.8 Dead zone range when automatically volume calculation
To insure the steady running of wire receiving machine near sway bar zero
position and avoid the influence to sway bar amplitude caused by volume
diameter automatically calculation,EDS1100 Series inverter set a certain dead
zone which near sway bar zero position, and this result in automatically stopping
volume diameter calculation in dead zone. The range of dead zone is:
F2.34=0.00~2.00V.
2.1.9 Automatically volume diameter calculation
When tension balance bar deviates central position, there should be some error
between volume diameter calculation result and its actual value, which needs to
calculate volume diameter. And different balance bar positions adopt different
calculation methods.
0.00V~F2.34: volume diameter calculation 0=dead zone
F2.34~F2.36：volume diameter calculation 1
F2.35~F2.37：volume diameter calculation 2
F2.36~F2.38：volume diameter calculation 3
F2.37~10.0V：volume diameter calculation 4
