Siemens SINUMERIK 828D Commissioning Manual page 459

You must define user-defined M-commands in the following machine data item:
MD22000 $MC_AUXFU_ASSIGN_GROUP
Bits 9, 10, 11 and 15 have a defined meaning in the following machine data:
MD22035 $MC_AUXFU_ASSIGN_SPEC
MD22080 $MC_AUXFU_PREDEF_SPEC
Bit 9
Bit 10
Bit 11
Bit 15
If a spindle is marked, the M-commands (direction of the spindle rotation, spindle chuck open/
closed, ...) that relate to this spindle should be output. This must be initiated explicitly in the
PLC (e.g. deactivate spindle via DB380x.DBX1.3).
If a channel is marked, M-commands (coolant, ...) that relate to this channel should be output.
To do this, use bit 15. Alternatively, you can also select an initiation in the PLC.
Typical settings for cross-channel M-commands (e.g. M3, M4, M5) are:
Bit 9 = 1, bit 10 = 1, bit 11 = 1, bit 15 = 0
Typical settings for cross-specific M-commands (e.g. M7, M8, M9) are:
Bit 9 = 1, bit 10 = 1, bit 11 = 0, bit 15 = 1
Calculating the program runtime
To calculate the program runtime, you can assign an average time to the M-commands in the
following machine data:
MD22037 $MC_AUXFU_ASSIGN_SIM_TIME
MD22090 $MC_AUXFU_PREDEF_SIM_TIME
You can increase the time with the following commands:
● $AC_PRTIME_M_INC, operating time
● $AC_PRTIME_A_INC, motor stop time
You can consider individually known times.
