Changing the direction of rotation with the DC1600/DA82GA direct-current positioning actuator
The direction of rotation of the coupling-positioning actuator
(three-phase motor) depends on its connection to the three-phase
supply. After connecting it to the three-phase supply 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 proximity-switch plug must be plugged in. See figure page 20.
–
Do not plug in the 37-pole plug of the sewing machine.
–
Turn on the main switch (motor-protection switch).
–
Because the 37-pole plug is not plugged in, no valid Autoselect
resistance is recognised and the maximum rotation speed is
limited.
–
Push the pedal slightly forward; the drive rotates; check the
direction of rotation.
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 sewing-drive
mains connection.
–
Insert the mains plug and turn on the main switch.
–
Check the direction of rotation (see section 6.6.3).
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 set-point generator, commutation switch, proximity
switch and operating panel must be plugged in. See figure page 20.
–
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 recognised 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.
If the sewing drive rotates the wrong way, technician-level parameter
F-161 must be set to the value 1.
For the V810 operating panel see section 6.11.4
For the V820 operating panel see section 6.11.5
Caution !
After a change in the direction of rotation the positions must be
reset. See section 6.10.
