Submenu
Selecting 2 and subsequent items calls the submenu screen of each
item.
Indication of “–-” in the submenu means the check is not sup-
ported with the model.
For example, if “5. Supply” is selected, the following submenu
will be displayed.
### Syscon Diagnosis ###

Quit the submenu and return to the main menu.
1. All
All submenu items continuous check.
This menu checks 2 and subsequent items successively. At the item
where visual check is required for judgment or an error occurred,
the checking is suspended and the message is output for key entry.
Normally, all items are checked successively one after another au-
tomatically unless an error is found.
Selecting 2 and subsequent items executes respective menus and
outputs the results.
For the contents of each submenu, see “General Description of
Checking Method” and “Check Items List”.
General Description of Checking Method
2. Version
(2-2) Revision
ROM revision number is displayed.
Error: Not detected.
The revision number defined in the source file of ROM
(IC106 or 107) is displayed with four digits.
(2-3) ROM Check Sum
Check sum is calculated.
Error: Not detected.
8-bit data are added up to the ROM (IC106 or 107) address
0x000F0000 to 0x002EFFFF, and the result is displayed
with 4-digit hexadecimal number. Error is not detected.
Compare the result with the specified value.
(2-4) Model Type
Model code is displayed.
Error: Not detected.
The model code read from the EEPROM is displayed with
2-digit hexadecimal number.
(2-5) Region
Region code is displayed.
Error: Not detected.
The region code determined from the model code is dis-
played.
(2-6) M't check
Error 22: region code discord.
Accordance between region codes, one is detected with
model resistance and destination resistance, and the other
is detected with region resistance, is check.
If an error is detected, the region code determined with re-
gion resistance is displayed at “write data” and the region
code determined with model resistance and destination re-
sistance is displayed at “read data”.
3. Peripheral
(3-2) EEPROM Check
Data write
→
read, and accord check
Error 03: EEPROM write/read discord.
0x9249, 0x2942 and 0x4294 are written to the address 0x00
to 0xFF of the EEPROM and then read for checking. Be-
fore writing, the data are saved, then after checking, they
are written to restore the contents of EEPROM.
(3-3) Gate Array Check
Data write
→
read, and accord check
Error 02: Gate Array write/read discord
Data of 0x00 to 0xFF is written sequentialy to the address
0xF and then read for checking.
(3-4) NAND FLASH Check
Data delete
→
write
→
read, and accord check
Error 04: delete error
Error 05: write error
Error 06: read data discord
Error 21: more than ten blocks are defective
Deleting, writing and checking read data are executed to
the zeroth block of Flash memory.
If any detective block is found, the address is displayed.
When more than ten blocks are defective, it is considered
as an error.
(3-5) SACD check
Device reset
→
internal organs RAM check
Error 50: Write and read data discord.
(3-6) VENC Check
Data write
→
read, and accord check
Error 52: Write and read data discord.
Accessing to the SYSCON may be defective.
(3-7) ––––––– (not support)
(3-8) EX RAM Check
Test Data write
→
read, and accord check
Error 02: The external RAM used in the system control is
checked.
4. Servo
(4-2) Servo DSP Check
Data write
→
read, and accord check
Error 12: Read data discord
0x9249, 0x2942 and 0x4294 are written to the RAM ad-
dress 0x602 of the Servo DSP and then read for checking.
Also, OPT type “1 LASER” or “2 LASER” is displayed.
