6.9 Direction of rotation of sewing drive
Caution:
Before the special sewing machine is started it is essential to
check the direction of rotation of the motor.
Switching it on can cause damage if the direction of rotation is
incorrect.
6.9.1 Checking the direction of rotation of the clutch motors (mounted under the table)
The direction of rotation of the clutch motor (three-phase motor)
depends on its connection to the three-phase supply. The direction of
rotation must be checked before use. Proceed as follows:
–
Connect the clutch motor and earthing and connect the sewing
drive to the mains.
(see sections 6.3.1, 6.4 and 6.5).
–
Turn on the main switch.
–
Operate the pedal (or the motor’s clutch lever) until the belt pulley
turns.
–
The belt pulley must turn anti-clockwise (looking at the belt
pulley).
6.9.2 Changing the direction of rotation of the clutch motors (mounted under the table)
If the sewing drive rotates the wrong way, the phases on the terminals
of the mains connection of the sewing drive 2 must be reversed. This
is done as follows:
–
Turn off the main switch and remove the mains plug.
–
Reverse two of the t hree phase conductors in the mains plug.
–
Insert the mains plug and turn on the main switch.
–
Check the direction of rotation (see section 6.9.1).

9800 129002 B or 9800 139001 B.
–
Stick the adhesive label with the safety instruction on the front of
the main switch .
–
If the sewing-lamp transformer is connected to a 3 x 380 - 415V
three-phase supply it must have a neutral conductor.
Caution !
The sewing-light transformer is directly connected to the mains.
It is therefore live even when the main switch is switched off.

–
Set the correct machine class with parameter F-290 according to
the corresponding parameter sheet 9800 331104 PBXX.
–
In order to position the machine correctly and to optimize all
functions the following parameters must still be set:
Parameter F-111: set to 3.000 rpm or less.
Parameter F-270: set to 6 (selection according to the position sensor)
Parameter F-272: can be calculated according to the formula below:
Motor pulley diameter (teeth)
x 1000
Machine pulley diameter (teeth)
Inserted needle: up to a thickness of 160.
Due to the gear reduction of 1,55:1 the maximum possible speed
is 3.000 rpm.
Due to the new transmission ratio of 1,55:1 a higher torque and a
higher penetration force of the needle of about 30% above a
transmission rate of 1:1 is achieved.
In order to achieve an even higher penetration force, the parameter
F-225 can be set from value “0" to value ”1".
It may happen, that the motor produces a snarling noise.
If this is the case, the toothed belt between motor and machine must
be tightened.

6.15 Setting machine-specific parameters
6.15.1 General
The functions of the sewing-drive control are determined by the
program and the parameter settings.
All parameter values for the relevant machine class and subclass are
pre-set by Efka prior to delivery of the sewing drives. For each class
and subclass some parameters at technician and manufacturer level
must be changed so that the control is perfectly coordinated with the
machine. The parameters concer ned are listed in the parameter sheet
(in the accessory pack).
6.15.2 Autoselect
The control “recognizes” which machine series is connected by
measuring the Autoselect resistance in the machine. Autoselect
selects control functions and the pre-set parameter values. If the
control fails to recognize a valid Autoselect resistance (or any at all),
the drive runs only with the so-called emergency operating functions
to prevent machine damage.
