Reference position
The reference position is the starting position for all other positions. It
is defined as the position of the needle tip, with the needle descending
in the normal direction of rotation, at the level of the upper side of the
needle plate. With the control correctly set only the reference position
needs to be reset after the removal of the proximity switch: all other
positions are then automatically correct.
Position 1
In position 1, in the normal direction of rotation, the needle bar is
about 5 mm before bottom dead centre.
CAUTION !
The raised sewing feet must not come into contact with the needle bar.
Position 1A
This position is only required for internal functions of the DA82GA
control.
Position 2
In position 2 the thread lever is shortly after top dead centre. (The
thread must be cut.)
Position 2A
This position is only required for internal functions of the DA82GA
control.
Position 3
This position is not required for class 367
Position 3A
This position is not required for class 367
Once every rotation the digital proximity switch sends 512 pulses
(increments) and one extra pulse to the control. All needle positions
are determined by these pulses and the values of parameters F-170
and F-171.
The proximity switch requires no mechanical adjustment.
Caution !
All positions must be reset after:
1. the sewing drive has been operated for the first time
2. the sewing drive, drive control or drive control plate
have been replaced
3. the EPROM in the drive control has been replaced.
After the proximity switch has been removed and refitted or replaced
only the reference position must be reset.
