• The software stroke limit can be activated by
parameter setting.
• If the current value has been changed by the
current value change function, the new value is
stored.
[Range: -2147483648 to 2147483647 pulse]

At axis error occurrence, the error code
corresponding to the error definition is stored.
• If another error occurs during axis error
occurrence, the latest error code is ignored.
However, if a system-affecting error (error code:
800 to 840) has occurred, the old error code is
overwritten by the newest error code, which is
Md. 5 Axis error
stored.
code • The error codes 800 to 840 are stored into Md. 5
for all axes.
• When " Cd. 1 Axis error reset" (axis control data)
of the corresponding axis is turned ON, the axis
error code is cleared (to zero).
(Refer to "Section 13.2" for details of the error
codes.)
