6.2 Checking the direction of rotation

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.

The sewing drives are fitted t o the frames in t wo different positions.

The direction of rotation of the sewing drive depends on which frame is used.

MG 53-3 frame: MG 56-2 frame

left rotation right rotation

frame direction of sewing-drive rotati on

MG 53-3 MG 56-2

In the three-phase sewing drives used it is the rotating field of the supply voltage which determines the direction of rotation.

– Insert the mains plug. – Check the direction of rotation of the motor fan (behind the fan grille 1) by briefly

turning on the main switch. The arrows in the above illustration show the correct direction of rotation for the two frame types.

– If the direction of rotation is wrong, two phases in the mains plug must be swapped

over.

left rotation (anticlockwise) right rotation (clockwise)

CAUTION:

If the direction of rotation has been changed the positions must be reset or re-programm ed.

Caution: danger of injury

Turn off the main switch before adjusting positioning pulleys 1 and 4.

The utmost care must be taken when adjusting the positioning pulleys. The positioning pulleys and the generator (innermost) pul ley must not be damaged.

The position of positioning pulleys 1 and 4 determines the machine positions.

6.4.2 Quick QD554 / A51K01 sewing drive

No mechanical adjustment to the digital proximity switch is required. Only the reference position must be set prior to the machine’s first use.

The machine positions are registered by the proximity switch in steps (increments) and displayed. One revolution of the handwhe el i s equivalent to 480 steps. The display is updated every 2 steps. A change from one displayed value to the next thus corresponds to an angle of rotation of about 1.5°. The angle of positions 1 and 2 to the reference position is defined in each case by a fixed number of increments.

Reference position

The reference position is start i ng point for all pre-set positio ns. In the reference position the needle is just entering the needle plate. The tip of the needle is on a level with the upper side of the needle plate.

Position 1

In the 1st position the needle must be in the loop-stroke position, i.e. 2 mm after bottom dead centre.

On machines with thread clipper s t he severing process is initiated in the 1st position. Subclass eye of the needle and the surf ace of the needle plate are all at the same level.

position 2

In the 2nd position the thread lever must be just behind its upper dead centre.
