• 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.

① Use this to shift a display screen horizontally by one dot.
② 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.

2.8.2 REPLACEMENT 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 T racking 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:
(OPER./MAINTE) → F4 SYSTEM →3 0 (F MENU) INPUT →

△

2 (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) When the diagnostic function does not appear in F7 following “F SYSTEM”

being selected in the above operation, push (RETURN) a few times.

(Note 2) 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.

4.1 Power-on Procedure

①Enter (set) the PMC ladder and others.
②Enter (set) the NC parameters.
③Turn 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.

4.2 System 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

When initially starting up the system, press F5/SYSTEM CLR to initialize the system.
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
