Transmitted by 2-phase stepping motor separately, with the holding force
and 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
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

）
Transmitted by mono-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 mono-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.
