8.2 Basic operating procedures
8.2.1 Common items
• When the power is turned on, the following initial screen is displayed on the data setting
panel.
< When the PRG mode is selected >
*1: When an angle is already set to the output Y0, that ON angle is displayed.
< When the RUN mode is selected >
The display mode just before the power is turned off or just before the mode is changed over
to the PRG mode is displayed. (Refer to Paragraph 9.1.)
• When setting the ON/OFF angle of an output or the angle advance quantity of the automatic
angle advance function from the data setting panel, use the [
⋅
] key to enter "0.5 degree".
(For setting from the buffer memory, refer to Paragraph 6.2.)
Example: When setting "90.5 degree"
Press the [9], [0] and [
⋅
] keys. A decimal point is also displayed on the DEG display.
(Refer to Paragraph 8.3.5.)
• In the FX
2N
-1RM, modification of a program can be prohibited by registering a keyword or
setting the write-protect function of the built-in EEPROM.
When "Prt" is displayed while a program is modified, delete the registered keyword or reset
the write-protect function of the built-in EEPROM, then modify the program again.
• Handling of the [CLR] key
1 ) After having performed an erroneous operation or erroneous input, the last operation can
be undone by pressing the [CLR] key.
2 ) The error indication can be cleared by pressing the [CLR] key. When the [CLR] key is
pressed, the error indication currently displayed is cleared, and "STEP0" is displayed.
3 ) When the [CLR] key is pressed after a read operation was performed and while an angle
is displayed on the DEG display, the insertion mode is selected and the DEG display
becomes blank.
• Timing to save a program to the EEPROM
While the data setting panel is manipulated, data is written to both the buffer memory and the
EEPROM when the [GO] key is pressed.
8.2.2 Read
Read the specified program bank, the specified output and the specified step No.
When the [-] key is pressed, the item is moved in the order of "OFF angle of the previous step"
and "ON angle of the previous step" (, then stops at the step No. 0).
When the [+] key is pressed, the item is moved in the order of "OFF angle of the same step" and
"ON angle of the next step" (, then stops at the step No. 7).
When the [+] key is pressed and held for 0.3 sec or more, the next item is displayed in turn.
