6.2.2
Setting the machine positioning for DC1600/DA82GA motor drive and DC1550/DA321G
Position 1
The needle is down at the stopping in the seam. The angle 225° is on
the hand wheel scale.
Position 2
The needle is up after trimming. The angle 55° is on the hand wheel
scale using the VD552KV drive, and 45° using the DC1600 and
DC1550 motor drives.
The 1A and 2A positions are important only for the internal functions of
the DA82GA and DA321G controls.
For the needle and other elements positioning the incremental sensor
located on the hand wheel is applied which gives 512 impulses
(increments) and one additional impulse per rotation. In general, the
particular position is defined by the number of increments between this
position and the reference position. The increment number is set by
the corresponding parameter value (it is not, however, identical with
the parameter value). The position parameter values have already
been set - see chapter 6.1.3.1. The reference position still remains to
be set.
The reference position is defined by the angle 105° on the hand wheel
scale.
After dismantling, mounting, or replacement of the synchronizer a new
reference position must be set.
See the "Efka DA82GA" or "Efka DA321G" operating manual.
