1 Range of Applications
The drive is suitable for lockstitch, chainstitch and overlock machines of various manufacturers.
It can be operated with or without control panel.
The easy-to use V810 or V820 control panels extend the range of functions.
With the help of adapter cords (adapter cords see Special Accessories), the drive can be used in replacement of
the controls listed in the table below, as long as backtacking, stitch condensing, and chain suction are not used.

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!

3 Putting into Service
Before putting the control into service, the following must be ensured, checked and/or adjusted:
Selection of motor type using parameter 467
The correct installation of the drive, position transmitter and accompanying devices, if necessary
The correct selection of the trimming operation using parameter 290
If necessary, the correct adjustment of the direction of motor rotation using parameter 161
The correct selection of the functions of keys (inputs) using parameters 240...246
The setting of the transmission ratio between motor shaft and machine shaft using parameter 272
The setting of the type of position sensor using parameter 270
If necessary, the adjustment of the positions using parameter 171
if necessary, the setting of the positions using parameter 171 (possible with all settings of parameter 270)
The correct positioning speed using parameter 110
The correct maximum speed compatible with the sewing machine using parameter 111
The setting of the remaining relevant parameters
Begin sewing in order to save the set values

500
The Fast Installation Routine (SIR) passes through all parameters necessary for programming the functional
sequence and the positions.
With SIR you can do the most important settings for initial operation with menu prompting.
For safety reasons, the menu must be executed point by point. This ensures correct setting of all important
parameters.

5.3 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 with or without control panel
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.

5.4 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.
5.5 Functions of the Keys Inputs in1...in7
The function that is started when a button or switch connected to one of the inputs in1 to in7 is actuated can be
selected using parameters 240...246.

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.

transmitter information and actual mechanical position.
The reference position must be set:
