Built-in memory clear
Clears the contents of the standard ROM and backup RAM of the Motion CPU. During built-in memory clear, communication
with MT Developer2, execution of Motion SFC programs, and axis control cannot be performed. The procedure for built-in
memory clear is shown below.
1.
Set the rotary switch to "C".
2.
Turn the Multiple CPU system power supply ON.
3.
The READY LED turns ON, and the dot matrix LED displays "CLR". After 3 seconds, the dot matrix LED display switches
to the target memory.
4.
Pushing the SD memory card access control switch changes the dot matrix display as shown below. Select the memory
for built-in memory clear.
5.
By holding the SD memory card access control switch for longer than 3 seconds, "CLR"

"Memory selected in
procedure 4." is displayed alternately, and clear processing begins.
6.
When built-in memory clear is complete, "FIN" is displayed on the dot matrix LED.
7.
Turn the Multiple CPU system power supply OFF.
8.
Set the rotary switch to "0" to switch to normal mode.
• Do not turn Multiple system power supply OFF while the clear is processing.
• If Multiple CPU system power supply is turned OFF during clearing of standard ROM, accessing the
standard ROM may no longer be possible. Execute a drive format from MT Developer2, or perform a built-in
memory clear again.
• When an error is detected during the processing of a built-in memory clear, "ERR" is displayed on the dot
matrix LED, and the ERROR LED flickers. Perform a built-in memory clear again.
• The contents cleared in the standard ROM are every program, parameter, event history, and data for digital
oscilloscope. Refer to the following for details of each file.
