7.1 Motor QE3760
The motor is a synchronous motor. It has a permanent-magnetic rotor, a stator with three-phase winding
and an optoelectronic increment encoder for commutation and positioning.
The rated capacity of the motor (shaft capacity) is 370 W in S5 mode. The rated speed of the motor is
6000 rpm, the maximum speed is 9000 rpm.
The motor has two mains leads:
a) four-wire with special quadripolar AMP plug (X1) for connecting the stator coil to the control
system
b) six-wire shielded with nine-pole D-sub plug (X2) for connecting the increment encoder to the
control system.

7.2 Control system
Fig. 7.5 Fig 7.6
The control box is attached to the underside of the machine table by means of the four enclosed screws.
The mains connection is single-phase, using the three-wire cord protruding from the rear and a standard
safety plug.
The control system has peripheral functions

7.3 Speed control unit SWG2
The SWG2 is attached to the underside of the machine table with the enclosed brackets and connected
mechanically to the machine’s pedal by means of the enclosed rod assembly.
The mains connection of the SWG2 is by means of a nine-pole connector on plug X3 on the rear
control panel.
The SWG2 is an analogous mechanoelectronic converter, which converts the pedal path into analog
voltage. This analog output voltage of the SWG2 is digitized in the control system so that the pedal path
can be divided into 16 steps (positions).

8. Application
The MINI-TOP Type Q41MS is specially designed for overlock machines and is mainly conceived for
light-barrier control.
The connection of the light-barrier is possible either via the the external operators control panel OC-TOP
or directly at the socket X5 at the control box (Input E6).
The drive system includes three different functional sequences.
Selection of the functional sequences is made via parameter <799>.
Sewing work can be manual or programmed. Programmed sewing is only possible in conjunction with
the external oparator panel QC-TOP/DQ
Extent and contents of sewing programs
a) Number of sewing programs: 5
b) To each sewing program can be assigned the following functions
function: adjustment via:
rated stitchcount S1.x via keys A+/A-/B+/B-
rated stitchcount S2.x via keys C+/C-/D+/D-
rated stitchcount S3.x via keys L+/L-
chain vacuuming at start via key T6
chain vacuuming at end via key T7
chopper at start via key T11
chopper at end via key T12
presser foot position at sewing stop via key T13
presser foot position at program end via key T14
light-barrier via key T15
c) Sewing speed (rated speed) for seam sections S1.x and S2.x can be selected via keys A+/A-.
d) Sewing speed can be changed over between constant (automatic) and variable (treadle-controlled)
via key T2.
e) There is the possibility of running various sewing programs consecutively. During programming, the
subsequent sewing program is shown in digits 6 and 7 of the display and is entered via keys D+ or
D-.
00 means that only the current program is run. At the end of the program concerned, return is made
to its beginning.
