Transmitted by 2-phase stepping motor separately, with the holding force and without
proximity switch
It uses a small 2-phase stepping motor for lifting presser at every special embroidery head
and controlling its working height and limited height. At power-off, there is the holding force
when the clamp foot stays at the upper point, but not at the bottom point. No proximity switch is
taken for positioning. As default setting, the controller sets the foot at the bottom position when
user turns on the machine.
(4)
Transmitted by single-phase AC motor, 2 proximity switches
In this mode, the clamp foot working height relies on the rotation of the cam and the clamp
foot is raised to the limited height by one single-phase AC motor driving the clamp axis. At both
the upper and bottom points, a proximity switch is installed to adjust the clamp foot rising
height. Neither the upper nor bottom point has the holding force.
(5)
Transmitted by stepping motor(2-phase or 3-phase), 1 proximity switch
In this mode, the clamp foot working height relies on the rotation of the cam and the clamp
foot is raised to the limited height by the stepping motor that drives the clamp axis. At the upper
point, a proximity switch is installed for positioning. The bottom point is controlled by
parameters. Both the upper and bottom points have the holding force.
(6)
Transmitted by air valve separately, without proximity switch.
In this mode, the clamp foot working height relies on the rotation of the cam and the clamp
foot is raised to the limited height by air valve that acts at the heads separately.
