Explanation 

A memory data display format can be selected from the following four 
options: 
 
Byte display (1 byte in hexadecimal) 
Word display (2 bytes in hexadecimal) 
Long display (4 bytes in hexadecimal) 
Double display (8 bytes in decimal: Double precision floating-point 
display)  
 
One screen displays 256-byte memory data. 
 

NOTE 

1  When an address is input, "H" for representing 

"hexadecimal" need not be specified at the end of 
the address. If H is added, a warning is displayed to 
indicate that the format is invalid. 

2  When word display is selected as the display 

format, an input address is rounded to a multiple of 
2 bytes. When long display or double display is 
selected, an input address is rounded to a multiple 
of 4 bytes. 

 

 WARNING 

1  If a memory address that must not be accessed in 

address search is input, a system alarm is issued. 
When making an address search, check that the 
address is accessible and that the address is input 
correctly. 

2  This function is designed for maintenance, and must 

not be used by general users.

Parameter tuning screen (system setting) (15-inch display 

unit) 

 
This screen enables the parameters related to the entire system 
configuration to be displayed and modified. The parameters can be 
initialized to the standard values (recommended by FANUC). 
 

Display and setting 

Procedure

 or 

  on the parameter tuning menu screen described 

in Subsection III-12.4.27.1. 

2 

Press horizontal soft key [SELECT]. The screen display switches 
to the screen and horizontal soft keys shown below.

3 

Move the cursor to a parameter number to be set or displayed, 
according to one of the methods below. 

•

 

Input the desired parameter number, then press horizontal 
soft key [NO.SRH]. 

•

  Move the cursor to the desired parameter number by 

pressing page key 

 or 

, and cursor keys 

,

5  Press horizontal soft key [INIT]. The standard value 

(recommended by FANUC) for the item selected by the cursor is 
displayed in the key input buffer. Pressing horizontal soft key 
[EXEC] in this state initializes the item to the standard value. 

6  Press horizontal soft key [GROUP INIT]. A message asking 

whether to set the group standard values is displayed on the 
screen. Pressing horizontal soft key [EXEC] in this state inputs 
all of the standard values of the group. 

 

NOTE 

1  If the cursor is placed on a parameter that has no 

standard value assigned, no standard value is input 
even when [INIT] is pressed. 

2  When the cursor is placed on multiple bits for bit 

parameters, the multiple bits can be input 
simultaneously. When [INIT] is pressed in this state, 
the key input buffer displays the standard values for 
the bits where the cursor is placed. If a bit has no 
standard value assigned, "*" is displayed for the bit, 
and no value is input for the bit. 

3  When [GROUP INIT] is pressed, those parameters 

that have no standard values assigned are not 
initialized.
