Workpiece counting with user-defined M command
If the corresponding bit is set in MD27880, then the count pulse can be triggered via a user-
defined M command parameterized via the following machine data instead of via the end of
program M2/M30.
MD27882 $MC_PART_COUNTER_MCODE[<n>] (workpiece counting with user-defined M
command)
<n>
0
1
2
The respective workpiece counter is incremented by "1", when a user-defined M command is
called.
Supplementary conditions
● Mode change / NC RESET
The counters are not affected by a mode change or NC RESET.
● $AC_REQUIRED_PARTS ≤ 0
Where $AC_REQUIRED_PARTS ≤ 0 and MD27880 $MC_PART_COUNTER, bit 0 = 1, the
counting procedure and the identity comparison set with MD27880 are not conducted for
all the active counters.

Value Meaning
0 $AC_ACTUAL_PARTS is incremented by the value "1" through M02/M30.
1 $AC_ACTUAL_PARTS is incremented by the value "1" through the M command de‐
fined with MD27882[1].
0 $AC_ACTUAL_PARTS is also active for program test / block search.
1 $AC_ACTUAL_PARTS is incremented by the value "1" upon a jump back with GOTOS.
1 $AC_SPECIAL_PARTS is active.
0 $AC_SPECIAL_PARTS is incremented by the value "1" through M02/M30.
1 $AC_SPECIAL_PARTS is incremented by the value 1 through the M command defined
with MD27882[2].
0 $AC_SPECIAL_PARTS is also active for program test / block search.
1 $AC_SPECIAL_PARTS is incremented by the value "1" upon a jump back with
GOTOS.
Meaning
MD27882[0] defines the M command in which $AC_TOTAL_PARTS is incremented.
MD27882[1] defines the M command in which $AC_ACTUAL_PARTS is incremented.
MD27882[2] defines the M command in which $AC_SPECIAL_PARTS is incremented.
