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