Operation
- 3-14 - ULTRAFEEDER
P2.3 = A (Advanced):
[Allowed values 00 ÷ 850] ; in this mode the parameter indicates the speed in
m/min.
Choose the desired value using:
(to increase the value) or (to decrease the value).
to return to the beginning of P2 menu.
to switch to P3 menu.
to return to CONTROL status without programming P3 and P4 menus.
Example of Relax Yarn and Relax Speed Parameters Interaction
(V) = Nominal Yarn Feeding Speed = 100 m/ min
(A) = Main Tension (P1.1) = 2.0 g
(B) = Relax Yarn (P2.2) = 0.8 revs of the wheel at the speed defined in P2.3
(C) = Relax Speed (P2.3) = 03 (10 m/min) (Standard setting)
During the operation with nominal yarn feeding speed (V = 100 m/min), the ULTRAFEEDER
device operates with the tension set in MAIN TENSION (A), after a speed change and/or a
thread guide exit condition, the feeding speed decreases following a deceleration ramp and,
when it reaches the value programmed in RELAX SPEED (03 = 10 m/min in the example
above) the device will carry out a wheel rotation by the number of revolutions set on P2.2,
then it will stop.
