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 return to the beginning of P2 menu.
to switch to P3 menu.
to return to CONTROL status without programming P3 and P4 menus.
(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)

FEEDER Operating Tension
Yarn Guide Entry
During the operation with nominal yarn feeding speed (V = 100 m/min), the MULTIFEEDER
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.
