1 Range of Applications
The drive is suitable for lockstitch, chainstitch and overlock machines of various manufacturers.
The functions backtacking and stitch compression, are unsupported.
1.1 Use in Accordance with Regulations
The drive is not an independent functional machine. It has been designed for integration into other machines by
trained specialists.
It must not be put into service until the machinery into which it is to be incorporated has been declared in
conformity with the provisions of the EC Directive (Appendix II, paragraph B of the Directive 89/392/EEC and
supplement 91/368/EEC).
The drive has been developed and manufactured in accordance with the relevant EC standards:
IEC/EN 60204-31 Electrical equipment of industrial machines:
Particular requirements for industrial sewing machines, sewing units and sewing systems.
Operate the drive only in dry areas.
ATTENTION
When selecting the installation site and the layout of the connecting cable, the Safety
Instructions must be followed with no exceptions.
Particular attention should be paid to maintaining the proper distance from moving parts!

6.3 Transmission Ratio
NOTE
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.
ATTENTION
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

6.7 Maximum Speed Compatible with the Sewing Machine
The maximum speed of the machine is determined by the selected pulley and by the following settings:

A sensor can be used as a position sensor, e.g. Efka Hall sensor module (HSM1) or pulse generator (IPG) with
either NC or NO functionality.
It is connected to socket B18/7.
Parameter 270 is used to select the mode to be selected depending on the type and mounting of the sensor
used (see section Parameter List under parameter 270 for a description and flow chart).
After configuration of parameter 270 to "1, 2, 3 o 4", parameter 171 must be used to set the angle for positions 1
and/or 2, incoming and outgoing.
Alternatively, the positions can be configured using the fast-installation routine.
The transmission ratio must already have been input using parameter 272.

6.9.1 Setting the reference position (Parameter 170)
The angular positions necessary on the machine e.g. “needle down position“ or “thread lever up position“ are
stored in the control. A reference position is needed in order to establish a relationship between position
transmitter information and actual mechanical position.
The reference position must be set:
For initial operation
After replacing the motor

6.9.2 Setting the positions
This is an explanation of terms for the following descriptions:
Position 1 means "Needle lower position"
Position 2 means "Thread lever up" or "Needle rod TDC"
Each position has a starting angle (start) and ending angle (end). The needle stop position always refers to the
starting angle.

The position window 1 and position window 2 must not overlap. Consider that the width of the position window is
at least 30° (difference between start and end of the position)!
If positions are set via the Setting and Putting into Service with the Aid of the Fast Installation Routine (SIR),
then only the starting angle must be set. The end angles are automatically set to 60° after the starting angle.
The needle positions should in principle only be set via the quick installation routine (SIR) to prevent erroneous
inputs. You are guided through the required parameters with it.
See Section Fehler! Verweisquelle konnte nicht gefunden werden. Setting and Putting into Service with the
Aid of the Fast Installation Routine (SIR)
It is only important to set the position window including end angle for specific cutting systems. For these
systems, the cutting duration is controlled via the end angle of the position.

269
Determine by means of parameter 269 whether the drive is to stop exactly on the position (Parameter 269 =0)
or some increments after the position.

Parameter 207 regulates the braking effect between speed stages
Parameter 208 influences the braking effect for the stop
Parameter 219 influences the braking effect before the stop
The following applies to all setting values: the higher the value, the stronger the braking reaction!
6.13 Braking Power at Standstill
Function
Parameters
Braking Power at Standstill
(brt)
153
This function prevents unintentional "wandering" of the needle at standstill.
The effect can be checked by turning the hand wheel.
The braking power is effective at standstill
- at stop in the seam
- after the seam end
The effect can be set
The higher the set value, the stronger the braking power

6.14 Starting Characteristics
Function
Parameters
Starting edge
(ALF)
220
The drive acceleration dynamics can be adapted to the sewing machine characteristic (light/heavy).
High setting value = high acceleration
With a high starting edge setting and, in addition, possibly high braking parameter values on a light machine, the
characteristic may appear coarse. In this case, one should try to optimize the settings.

The integrated operating hours counter records the time of motor operation. Downtimes are not recorded. Time
recording accuracy is 1ms. There are two ways of operating hours counting.
1. Basic operating hours counting:
217 =0
Operational mode: Operating hours counting
2. Service Hours Monitoring:
217 =>0
Operational mode: Number of operating hours before the next service.
Input of operating hours before the next service.
This value is compared to the operating hours counter.
The input of hours is done in steps of 10. i. e. the lowest display of 001 corresponds to 10 hours
(e. g. 055 = 550 hours).
When the set number of operating hours are reached, the message "C1" will show on the display
after each trimming operation. In addition, the speed indicator blinks on the during operation or
after drive standstill..
176
In this service routine, the total operating hours can be read out according to the procedure
example described below for parameter 177.

6.15.1Set and Reset Operating Hours Counter
The number of hours has been reached (service necessary):
Press the >> key once

The operating hours counter is set to "0" and restarted.
The number of hours has not yet been reached:
Press the >> key three times

The operating hours counter is set also to "0" and
restarted.
A value in parameter 177 has been changed:
After displaying rES ..., when the Ekey is pressed again, SEt will then be displayed.
If the changed value is to be saved, press the >> key 3 times.
6.15.2Total Operating Hours Display
In this service routine enabled using parameter 176, the total number of operating hours is displayed.
The sequence of displayed values is as with parameter 177.
The values can only be displayed, not varied. Therefore, letter symbols "rES" for "reset" and "SEt" for "set"
will not appear.
