II] Outline

The MD600 Series AC servomotor is a substitute for the MDBOO Series DC servomotor, incorporating an induction motor. This motor is maintenance-free and has less noise. Improvements have been made in the vibration and heating, and the operability and reliability have been further improved with an all-digital control.

The model configuration follows the conventional MDBOO Series.

II] Features

<D Incorporation of induction motor

By incorporating an induction motor instead of the conventional DC motor, a stout motor without brushes, mechanical brake and magnet has been achieved.

®Maintenance-free

By using electric brake instead of the conventional mechanical brake, and by eliminating the brushes and mechanical brake, a completely maintenance-free motor with no wear parts has been realized.

®Quiet operation

Motor noise has been eliminated with the sine wave control without strain.

By using electric brake instead of mechanical brake, the sound of the mechanical brake conventionally heard when decelerating and stopping has been reduced.

By using an integrated structure for the box and motor, the vibration conveyed to the pedal has been made creating a user-friendly quiet environment.

@Lightweight

By using an induction motor, integrated box and motor structure, and resin case, the weight has been reduced to 15kg from the 21kg for the conventional DC motor. This lighter weight also makes setting up easier.

Furthermore, by using a cooling structure, the temperature rise of the motor'souter frame has been dropped by approx. 1ODC according to Brother comparisons.

@Strengthened functions

Ample memory switches and parameter settings that allow the functions and characteristics to be changed and an extensive self-diagnosis function are provided.

®All-digital control

With the all-digital control, the stitching speed can be input with numerical inputs from the operation panel instead of the conventional volume knobs settings, allowing accurate and swift settings.

<V Others

•A commercial tapered pulley (;so or ;106) can be used.

•The installation pitch onto the table is the same as the conventional clutch motor, etc.

C-1 Setting of maximum speed

1)When the stitching speed key [ G) 1is pressed once, the [ G) 1LED will light, and the maximum speed will display on the No. of stitches display section.

2)The No. of stitches can be set with the [ v 1and [ ~ 1keys.

3)When the single needle model is set, the speed can be set between 215spm and the DIP switch setting speed (max. 4700spm).

4)When the twin needle model is set, the speed can be set between 250spm and the DIP switch setting speed (max. 4000spm).

5)During stitching, the [ G) 1LED will go out, and the display will return to the backtacking display, etc.

C-2 Setting of start backtack stitching speed

1) When the stitching speed key [ G) 1is pressed twice, [ G) 1and [ 111 1 will light, and the start backtack stitching speed will display on the No. of stitches display section.

2)The No. of stitches can be set with the [ v 1and [ ~ 1keys.

3)When the single needle model is set, the speed can be set between 215spm and 1800spm.

4)When the twin needle model is set, the speed can be set between 250spm and 1000spm.

5) During stitching, the [ G) 1LED will go out, and the display will return to the backtacking display, etc.

00 Explanation of each mode

Besides the normal stitching mode_, the head setting mode, initialization mode, and memory switch setting mode, etc., can be entered using the operation panel and various settings can be made. (If the power switch is turned ON while holding down the designated key, the initialization and head setting modes 9an be entered. If the designated key is pressed while the thread trimming needle is stopped at the UP position in the stitching mode, the memory switch setting mode, etc., can be entered.)

(Note) This function can be used only when the F-40 or F-100 operation panel is connected. This cannot be used with the F-20 panel. Once the settings are made with the F-40 or F-1 00 operation panel connected, the set details will be registered even if the panel is disconnected.

8-2 Head setting mode

Before the motor is shipped from the factory, the motor product code is determined for each head and is set to match the specifications of the head. If the motor is to be used for another head, replace the pulley with an appropriate one (according to maximum speed), and select the head No. with this mode. The specifications will then match the head.

The heads that can be set are determined by the DIP switch 5 setting.

Always set the DIP switch (pulley size, single needle/twin needle, maximum speed) before making this setting.

The backtack stitching timing, etc., differs slightly according to the head. Thus, setting this mode accurately is recommended.

8-4. Stitching speed setting mode

Each speed can be changed as described below by using the stitching speed setting mode.

<D Setting of each stitching speed.

Normally, each speed determined by the product code corresponding to the head is set at the factory. To change the speeds, use the following procedures.

<D-1	Press the [ X		1key while holding down the [	AUTo	1key, and enter the mode setting menu 1.
<D-2	Press the [ _,!.!.		1+ [ AUTo 1keys, and enter the mode setting menu 2.
<D-3	Press the [	X	1key, and enter the stitching speed setting mode.
<D-4	Select the speed type to be changed with the 8 [A] key.
<D-5	When the [	X	] key is pressed, the display will change to the setting speed (numerical value).
	If [ .,!.!. ] is pressed at this time, the sewing machine will rotate at that speed. The display will monitor the ac-
	tual speed, and display it. If [ .,!.!. ] is pressed again, the sewing machine will stop.
<D-6	Set with the [A] and [ v] keys.
<D-7	If the [ X	1key is pressed, the display will return to the setting speed type.
(i)-8	Press the 8 [A] key several times, and display [			E n	1.
(i)-9	When the [	X	] key is pressed, the mode setting menu 1 will be returned to.
<D-10	Press the 8 [A] key several times, and display [			E n	1.
<D-11	When the [	X	] key is pressed, the stitching mode will be returned to.

The display and order of each speed type are as follows.

Speed type		Display	Setting unit	Setting range	Remarks

Inching speed		L o	1spm unit	150-280spm	Speed for low-speed stitching and correc-
					tion setting.

Thread trimming speed		1: r	1spm unit	150spm-inching speed	Speed for thread trimming

Slow start speed		5 L	100spm unit	Inching speed-1 OOOspm	Speed for slow starting
Start backtack stitching limit		I	100spm unit	Inching speed-3000spm	Limit speed for start backtack stitching
Start backtack stitching limit		1.. I	100spm unit	Inching speed-3000spm	Limit speed for start backtack stitching
speed

End backtack stitching limit		E b	100spm unit	Inching speed-3000spm	Limit speed for end backtack stitching
speed

High-speed stitching limit		H.	50spm unit	Inching speed-DIP switch-	Limit value for maximum stitching speed
speed	(Note 1)			setting

Automatic stitching speed		AU	100spm unit	Inching speed-High speed	High speed for automatic stitching
				stitching limit speed

Stop improvement speed		p 0	100spm unit	500-2500spm	Middle speed for stop time improvement

(Note 1) The upper limit of the maximum stitching speed limit value is limited by the DIP switches 6, 7 and 8 shown in

	Table [1]-8.
	If 5000spm is set with DIP switches 6, 7 and 8, (when ¢105 pulley, single needle are designated), the speed can
	be set to a maximum of 5000spm.
(Note 2)	If the DIP switch 2 or 5 setting is changed, all these speed settings will be initialized.
	The 1!1 8-2 head settings will also be initialized (*).		l 3 l 3 ] )
	a) When DIP switch is set to OFF (Initialized to head setting [		l 3 l 3 ] )
		Thread trimming speed = 215spm
	(	Inching speed= 215spm
		Start/end backtack stitching speed= 1800spm, etc.	8 Y 2 3 ] )
	b) When DIP switch is set to ON (Initialized to head setting [		8 Y 2 3 ] )
		Thread trimming speed = 185spm
	(	Inching speed= 250spm
		Start/end backtack stitching speed= 1000spm, etc.
(Note 3)	The setting range A U on the old CPU version (J02781-A) is as follows.
