» FOOT PRESSURE CONTROL
ADVICE!
Automatic foot pressure control
On conventional machines the foot pressure is generated by a spring and will be adjusted seldom. The VETRON also
generates the foot pressure with a spring, but the spring is pre-stressed by a step motor with gear (parameter 050 ). In
different programs can different foot pressure be applied. You have the choice between three operation modes (parameter 054 ).
Operation mode: 1 = OFF Foot pressure is generated like on a conventional machine.
Can be different depending on the program.
2 =
CONSTANT
The foot pressure will be constant on all material thicknesses. The material thickness recog-
nition will make sure that the foot pressure control that you have a constant foot pressure.
3 = 1-100 % The foot pressure will be increased with increased sewing speed. Low percentage will
increase the pressure only weak. High percentage will increase the pressure stronger.
ADVICE!
When sewing operations are done where the foot pressure is used to keep the material in position (e.g. piping), it is
advisable to use operation mode 1 ( OFF ). Operation mode 2 ( CONSTANT ) will lead to a negativ result. The material
thickness recognition will prevent positioning the piping.
050 Foot pressure
You can set the foot pressure for the program here. Comparable to a conventional
machine.
054
Dynamic foot pressure
The following functions are available:
Function 1 =
OFF
Function 2 = CONST
Function 3 = %
