•Perform adjustment with “HS AB” and “PHS 01234” when dots slippage causing flicker takes place on switching between an MMC page and an NC page. First, change “PHS 01234” and set it so that no flicker takes place. When adjustment cannot be made even through this, change “HS AB”.

•Use “HS 012” to adjust by one dot when an MMC and an NC page are not equal in their horizontal position.

•Adjust luminance blur with “LCD ADJ.” on the main board for the NC page. For the MMC page, make adjustment with “LCD ADJUST” of the MMC-IV board.

On occurrence of flicker on the screen, change setting of the set pin TM1 into the other. Normally, flicker can be eliminated in one of these two ways.

•SW1 (Setting of Horizontal Position)

Use this to shift a display screen horizontally by one dot.

Use this to set position where all displays are available. There is only one place for toral display. As it is normally set prior to shipment, no change is necessary.

Note

Do not change any setting, volume, etc. other than those mentioned above. A change, if made in any setting other than the above, results in incorrect screen display.

2.8.2REPLACEMENT OF FUSE

(1)Check the fuse on the front panel of the data server board for any disconnection. On occurrence of disconnection, a white marker appears in a small window of the fuse.

(2)Remove the cause which has disconnected the fuse.

(3)Pulling out the disconnected fuse, insert a new one of the same specification.

3. TROUBLESHOOTING

When a trouble happened, check “when it happened,” “what you were operating,” “what it was like,” and “how often it happens.”

3.1 Tracking through the ALARM Screen

When an alarm happened during operation, an alarm message appears on the top area of the screen.

For some alarms, the details are displayed on the diagnostic screen. Confirm, then, the description on the diagnostic screen in the following operation:

[Display Operation of Diagnostic Screen]

While NC “General Screen” is displayed, operate as:

2

(OPER./MAINTE) → F4 SYSTEM → 3 0 (F MENU) INPUT → (F_SYSTEM) INPUT → F7 DGNOS

to display the diagnostic screen. Input, then, a number to be referred to and push F6 NO.SRH . Data for the diagnostic number are displayed. (The page key is

useable to make a change.)

(Note 1)

(Note 2)

When the diagnostic function does not appear in F7 following “F SYSTEM” being selected in the above operation, push (RETURN) a few times.

Use	ALTER	, not		(RETURN), for return operation from the
diagnostic screen.

3.2 Tracking through the Controller’s Monitor LEDs

Each unit in the controller has monitor LEDs so that you can check for the status of each unit. For details, see 2. FUNCTIONS AND HANDLING OF CONTROL UNITS.

4. POWER-ON ADJUSTMENT

4.1Power-on Procedure

Enter (set) the PMC ladder and others.

Enter (set) the NC parameters.

Turn off the power and turn it on again.

(Note) When system software has not been entered into the NC internal memory, transfer it into the NC internal memory according to the instructions in [APPENDIX] BOOT SYSTEM, and then, go through the above-mentioned steps.

4.2System Table

This CNC unit sets allocations of the data areas such as machining program, tool offset amount through the "system table."

To display the System Table screen, operate in the following order in the Overall screen:

OPER./MAINTE → F4/SYSTEM → 2 5 (SYSTEM TABLE) → INPUT

	SYSTEM TABLE
	BASIC RAM SIZE			38E40					EXT. RAM SIZE				0
		No.	TABLE	SIZE	OFFSET			No.	TABLE		SIZE		OFFSET
		01	SYSTEM	10000	0			11			0		0
		02	TOOL	5000	0			12			0		0
		03	SPARE	3900	0			13			0		0
		04	MONI	6F00	0			14			0		0
		05	PRGRM	13000	0			15	DUMMY		6600		32800
		06		0	0			16			0		0
		07		0	0			17			0		0
		08		0	0			18			0		0
		09		0	0			19			0		0
		10		0	0			20			0		0
When initially starting up the system, press										to initialize the system.
						F5/SYSTEM CLR

When this is done, the basic RAM capacity and extended RAM capacity are automaticlly set. Pressing F3/TABLE brings the cursor into the table. In accordance with the names versus capacities table provided on the next page, set the table names and capacities, using [Cursor] and [Alphanumeral] plus the INPUT key.

1 - 25

(Note 1) The numbers 01 through 15 are the tables for the basic RAM, and 16 through 20 are those for the extended RAM. When the extended RAM capacity is 0 (zero), do not set for the numbers 16 through 20.

(Note 2) Set the capacity in an increment of 100, suffixing a numeral with “H” (indicates hexadecimal)

(Note 3) If the capacity is entered, the offset for the next table will be automatically set. Different from the S-III, however, the last table capacity is not adjusted. Set a dummy table before the last table capacity so that it will be of specified capacity.

(Note 4) The table number 01 has a fixed table name, “SYSTEM,” and capacity, “1000H.” For the other tables, you can set any table names in any places.

(Note 5) A standard set value varies from one model to another. When actually setting it, follow the materials for each model.

(Note 6) When the system table is changed, be sure to turn off and on the power to make sure that “790 System Table Error” does not occur, and then, start
