1 Important Safety Instructions
When using an EFKA drive and accompanying devices (e g
for sewing machines), basic safety precautions should
always be followed, including the following:
§ Read all instructions thoroughly before using this drive.
§ Drive, its accessories and accompanying devices should
be mounted and put into operation by qualified personnel
in accordance with the guidelines provided in the
instruction manual.
To reduce the risk of burns, fire, electric shock, or
personal injury:
§ Use this drive only for its intended use as described in the
instruction manual.
§ Use only attachments recommended by the manufacturer
or as contained in the instruction manual.
§ Do not operate without corresponding protective devices.
§ Never operate this drive if one or more parts (e. g. cables,
plugs) are damaged, if it is not working properly, if any
damages can be identified or are to be suspected (e. g.
after it has been dropped). Only qualified personnel are
authorized to make adjustments, eliminate faults and
complete repair work.
§ Never operate the drive with the air openings blocked.
Keep ventilation openings of the drive free from the
accumulation of lint, dust and loose cloth.
§ Never drop or insert any object into any opening.
§ Do not use drive outdoors.
§ Do not operate where aerosol (spray) products are being
used or where oxygen is being administered.
§ To disconnect, turn off main switch, then remove plug
from outlet.
§ Do not unplug by pulling on cord. To unplug, grasp the
plug, not the cord.
§ Keep fingers away from all moving machine parts. Special
care is required e. g. around the sewing machine needle
and the V-belt.
§ Before mounting and adjusting accompanying devices, i.e.
position transmitter, reversing device, light barrier, etc.,
disconnect drive from mains (turn off main switch,
remove mains plug from outlet [DIN VDE 0113 part 301;
EN 60204-3-1; IEC 204-3-1]).
§ Always switch off (0) machine and remove plug from
outlet, when removing covers, mounting accompanying
devices, position transmitter especially, light barrier, etc.,
or any other devices mentioned in the instruction manual.
§ Only qualified personnel are authorized to work on the
electrical components.
§ Work on high voltage circuit areas is forbidden, except as
stated in the respective regulations, e.g. DIN VDE 0105
part 1.
§ Only specially trained personnel are authorized to
complete repair work.
§ Cables to be wired must be protected against expectable
strain and fastened adequately.
§ Cables near moving machine parts (e. g. V-belts) must be
wired at a minimum distance of 25 mm (see DIN VDE
0113 part 301; EN 60204-3-1; IEC 204-3-1).
§ For safety it is preferred to wire the cables separately from
each other.
§ Before connecting the mains line make sure that the mains
voltage corresponds to the specifications on the motor
rating plate and on the nameplate of the power pack.
§ Connect this drive to a properly grounded outlet only. See
Grounding Instructions.
§ Electric accompanying devices and accessories must only
be connected to safety low voltage.
§ EFKA DC drives are protected according to overvoltage
class 2 (DIN VDE 0160 § 5.3.1).
§ Observe all safety guidelines before undertaking
conversions or modifications.
§ For repair and maintenance use only original replacement
parts.
Warnings in the instruction manual
which point out particular risks of
personal injury or risk to the machine
are marked with this symbol wherever
applicable.
This symbol is a warning on the control
and in the instruction manual. It
indicates hazardous voltage.
CAUTION – In the case of failure this
area can be current-carrying even after
having turned the power off (non
discharged capacitors).
§ The drive is not an independently operating unit, but is
designed to be incorporated into other machinery. 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.
Save these instructions for future reference.

767, 768, 4180 und 4280
2.1 Use in Accordance with Regulations
The drive is not an independently operating machine, but is designed to be incorporated into other machinery. 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:
EN 60204-3-1:1990 Electrical equipment of industrial machines:
Particular requirements for industrial sewing machines, sewing units and sewing systems.
Operate the drive only in dry areas.

5.5 Keys for Background Information (HIT) with V820
(key assignment see figure on the last page)
For fast operator information, the values of functions switched on using key 1, 2, 3, 4 or 9 are displayed on the control
panel for approx. 3 seconds. During this time, the respective values can be varied directly by pressing the +or -key.
5.5.1 Example of HIT

Function key F
Various parameters, even higher-level parameters, can be switched on or off by pressing the function key (9 key).
The following functions may be assigned to the function key:
1. Softstart ON/OFF
2. Ornamental backtack ON/OFF
3. High lift for walking foot operational mode stored = ON / operational mode not stored = OFF
4. Needle cooling ON/OFF
5. Signals A1 and/or A2 On/Off with slide-in strips 1...4 (lefthand arrow = A1, righthand arrow = A2)

5.5.2 Further Functions of the V810/V820 Control Panels
§ Press the >> key èThe most significant digit blinks.
§ Press the +/- key briefly èThe blinking digit changes by ±1.
§ Keep the +/- pressed down èThe blinking digit keeps changing its value, as long as the key is
pressed down.
§ Press the >> key once more èThe next digit blinks.
§ Press the +/- key as above!
§ Press the Ekey èThe setting is completed.
With the code number and parameter number there is no carry over when changing from 0 to 9or vice versa. Parameter
values are, however, carried over. Therefore, you can use the +/- keys to change the value beween the minimum and
maximum value.
If the value change is significant, it is better to use the >> key. If the value change is insignificant, use the +/- keys.
For setting the minimum or maximum value, select the most significant digit using the >> key. Then keep pressing the –
key for the minimum or the +key for the maximum value.
The above description is applicable to both control panels, V810 and V820. Direct input of values is possible with the V820
using the 0...9 keys.
