15.3 TOP MENU is not Displayed
The menu key should be operated to access the Top Menu. Push the keys “OK” and “ESC” at
the same time. If the menu call key is not set, use either the programming software to the Stop
mode or do the forced stop operation.
The Top Menu cannot be accessed from the keys. However, by cycling the power supply and
pressing the “OK + ESC” keys simultaneously during the power up, the Top Menu will appear.
Caution
Perform the forced stop operation only after thoroughly checking that it is safe to do so.
Damage to the machine or controller or a safety issue could arise if the forced ON/OFF is
performed inappropriately.
If proper precautions are not taken, damage to the equipment or machine failure may occur.
Forced Stop Operation
1) Turn the α2 series power supply off.
2) Turn the power ON again while pushing the “OK” and
“ESC” keys simultaneously.
The screen at right is displayed.
The option to place the controller in Stop mode will be
available for approximately five seconds. Press the
“OK” key to enter the Stop Mode. If no key is pressed,
the controller will default back into the Run mode.
3) Push “ESC” key.
The “Top Menu” shown at right is displayed.
