Items
The currently commanded address can be stored.
When the current value is changed with the current value
change function, the changed value can be stored.
(It returns to the address before change by the system
power supply ON/OFF.)
The command output speed of operating axis can be
stored. The command speed of each axis at the
interpolation operation.
(A feedrate calculated from movement amount for every
axis can be stored. The movement amount might not
steady at the fixed speed either because of the fractions
generated when operating. Therefore, a value different
from the speed set in the positioning might be stored.)
The ON/OFF state of the external input signal can be
stored. The following items can be stored.
b15 to b12
0 0 0
(Note): The state of signal can be stored regardless of a
A positioning data No. currently being executed can be
stored.
"0" can be stored at the except for positioning execution.
An error code corresponding to error content can be
stored at the error detection. Always, a latest error code
can be stored. (If new error will occur, the error code can
be updated. However, a system error cannot be
updated.)
An error code can be cleared by setting "1" in "
error reset".
A number of error details corresponding to error content
can be stored at the error detection. (If new error will
occur, a detail corresponded to new error can be stored.)
An error detail can be cleared by setting "1" in "
Axis error reset".
A warning code corresponding to warning content can be
stored at the warning detection. Always, a latest warning
code can be stored. (If new warning will occur, the
warning code can be updated.)
A warning code can be not automatically cleared even if
the warning can be released on the servo amplifier side
at the warning detection.)
