• When the setting for (D) or n has been indirectly designated using an index
register (Z, V).
(2) In the following cases, a minor error (error on control change) occurs and the
current value change is not executed.
When this happens, the error detection flag (M1607+20n) is turned ON and the
error code is stored in the minor error code area for the relevant axis.
• When the axis designated in (D) for the current value change is in motion.
(1) The program shown below changes the current value for axis 2 to the value
designated with an 8-digit digital switch.
