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 o n 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 drivetothemains. (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 three 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).

6.9.3 Checking the direction of rotation with the direct-current positioning actuator

The direction of rotation of the direct-current positioning actuator is factory-set to right-to-left by entering the value 1 in parameter F-161. Even so, the first commissioning stage must be to check the direction of rotation. Proceed as follows:

–

The proximity switch must be fitted. See section 6.7.

–

The plugs of the s et-point generator, commutation switch, proximity switch and operating panel must be plugged in. See figure page 23.

–

Do not plug in the 37-pole plug of the sewing machine.

–

Turn on the main switch. The operating panel displays “Info A5", which means that no valid Autoselect resistance is recognized and the maximum rotation speed is therefore limited.

–

Push the pedal slightly forward; the drive rotates; check the direction of rotation.

–

Replace the 37-pole plug of the machine head.

6.9.4 Changing the direction of rotation with the direct-current positioning actuator

If the sewing drive rotates the wrong way, technician-level parameter

F-161 must be set to the value 1.

Caution ! After a change in the direction of rotation the positions

must be reset.

6.9.5 Adjusting the positions with the VD552/6F82FA coupling-positioning actuator

General

The proximity switch contains an inner disc (generator disc) with increments for regulating the rotation speed, a center, adjustable disc 1 for position 1 and an outer, adjustable disc 2 for position 2.

Caution ! Exercise extreme care when adjusting the position discs . Caution: danger of injury Please ensure that the position discs and the generator

disc (the innermost disc) are not damaged.

6.10 Setting machine-specific parameters

6.10.1 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 concerned are listed in the table below and in the parameter sheet (in the accessory pack).

6.10.2 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.

See the “EFKA DA82GA” or “EFKA 6F82FA” operating manual.

6.11.1 Attaching and connecting the sewing light transformer (optional equipment)

–

Remove the machine’s mains plug.

–

Pass the mains cable 1 of the sewing-lamp transformer through the cable conduit 2 to the main switch.

–

It is connected to the mains-connection side of the main switch (or motor-protection switch). See connection diagram 9800 169002 B, 9800 129002 B or 9800 139001 B.

–

Stick the adhesive label with the safety instruction on the front of themainswitch .

–

If the sewing-lamp transformer is connected toa3x380-415V 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. The mains plug must be removed before carrying out any work on the sewing-light transformer, e.g. changing the fuse.

6.12.1 Connecting the Hall-effect sensor (Optional Equipment)

Only with DC 1550 drive:

Motor mounted under the table

Gear reduction motor - machine 1,55:1

Attention !

Turn off the main switch. Connect the Hall-effect sensor with the sewing machine switched off.

–

Fit the Hall-effect sensor 1 onto the machine head.

–

Check whether a magnet is fitted into the belt pulley 2 of the machine. The magnet is positioned on the inner side of the belt pulley towards the machine.

–

If no magnet is fitted into the belt pulley 2, it must be exchanged. If the belt pulley is fitted correctly, the magnet must be positioned above the Hall-effect sensor, when the tip of the needle penetrates into the throat plate.

Connect the 9-pole SuB-D plug of the Hall-effect sensor to the bushing “B18" (IPG / HSM / LSM) of the Efka control drive DA321G.

–

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: setto6(selectionaccordingtothepositionsensor) Parameter F-272: canbecalculatedaccordingtotheformulabelow:

Motor pulley diameter (teeth)

x 1000

Machine pulley diameter (teeth)

Inserted needle: up to a thickness of 160. –

The correct machine class must be set with parameter F-290. In order to do so, consult the corresponding parameter sheet 9800 331104 PBXX.

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 c ase, the toothed belt between motor and machine must be tightened.
