Function
Contains the total time that the power has
been ON.
Contains the total time that the CPU Unit has
been ON in 1-hour increments.
To reset this value, overwrite the current value
with 0.
The value is not updated after it reaches
4294967295.
This variable is not initialized at startup.
Contains the number of times that the power
supply has been interrupted. The value is
incremented by 1 each time the power supply
is interrupted after the first time that the power
was turned ON.
To reset this value, overwrite the current value
with 0.
The value is not updated after it reaches
4294967295.
This variable is not initialized at startup.
TRUE at the following time (failure of retention
during power interruptions).
• When an error is detected in the battery-
backup memory check at startup.
FALSE at the following times (no failure of
retention during power interruptions).
• When no error is detected in the battery-
backup memory check at startup.
• When the user program is downloaded.
• When the Clear All Memory operation is
performed.
Note When the encoder home offset data is
not retained, the status is given in the
error status of the axis variable, and not
in this flag.
Meaning
The unit version of the CPU Unit is stored.
The integer part of the unit version is stored in
element number 0.
The fractional part of the unit version is stored
in element number 1.
Example 1) If the unit version is 1.08, "1" is
stored in element number 0 and "8" is stored
in element number 1.
Example 2) If the unit version is 1.10, "1" is
stored in element number 0 and "10" is stored
in element number 1.
