6.3 Transmission Ratio
N
OTE
The transmission ratio must always be input if no transmission ratio of 1:1 exists, because only motors with
integrated incremental transmitters will be used.
The transmission ratio should be determined and set as
precisely as possible!
The transmission ratio between motor shaft and shaft of the sewing machine head must be input, so that the set
speeds of parameters
110...117
correspond to the sewing speeds.
Function
Parameters
Transmission ratio between motor shaft and machine shaft
(trr)
272
The transmission ratio can be selected within a range of 150...40000 using parameter
272
.
Example:
With a motor pulley diameter of 40 mm and a sewing machine head pulley diameter of
80
mm
the
value
500
can
be
calculated
using
the
formula
below.
If the value 2000 has been selected in parameter 272, it follows that the motor pulley is
double the size of the sewing machine head pulley.

6.4 Selection of Functional Sequences (Thread Trimming Operations)
This drive is suitable for different lockstitch, chainstitch and overlock machines. The mode for the functional
sequence required on the respective machine can be selected using parameter
290
.
A
TTENTION
Before switching the functional sequences, you must disconnect input and output plug-and-
socket connections between control and machine. Please ensure that the functional sequence
(mode) suitable for the respective machine is selected.
Settings with parameter 290 are possible only after the power is turned On.
You will find a summary of the modes that can be set and the corresponding machines and adapter cords, to
include available output signals in the List of Parameters chapter: Table of adapter cords.
Further information see chapter "Timing Diagrams" for the various modes.
The possible functions are listed in the section "Parameter list".
6.5 Key functions of the input in1
The function which is triggered by pressing a button or switch connected to input in1 can be selected with
parameter 240.
The possible functions are listed in the section "Parameter list"
6.6 Positioning speed
Function
with
or
without
control panel
Parameters
Positioning speed
(n1)
110
The positioning speed can be set using parameter
110
on the control within a range of 70...390 RPM.
