specification parameter "#1170 M2name" A, B or C address that is not being used for
"#1013 axname" or "#1014 incax".
[Operation]
"2nd M function data" are updated when:
(1) "B (A, C)**" is specified in automatic operation (memory or MDI).
(2) "B (A, C)**" is executed by manual numerical command input.
Data remain unchanged even after "M function finish" signal (FIN1 or FIN2) is sent back. Data
cannot be cleared by "Reset" or "Emergency stop".
