Working method of the MC signals (MC_A and MC_B)
For each program (A or B), a separate MC signal is generated
internally in the SPC200 for each axis addressed. The MC
output for the relevant program supplies a 1−signal if all relĆ
evant internal MC signals supply a 1−signal (AND linking).

Please note
If an NC record is processed with the following NC comĆ
mands, the status of the MC signal will be undefined:
Ĉ M10, nominal value mode 1
(Activate nominal value input)
Ĉ M39 (Start valve variable output)
Ĉ M12 (Stop axis)
When nominal value mode 1 is started or after direct outĆ
put of a valve variable, the MC signal of the relevant axis is
constantly 1.
Axis status flags F72...75 can be used to poll the MC signals
of each axis, and to use them in programs, see chapter 7.2.
