9.15.3.2
Replacement of M40 - M45 (gear stage change)
Function
When a coupling is active, the commands for gear stage change (M40, M41 ... M45) of the leading spindle are
replaced by calling a user-specific subprogram.
Parameterization
Activation
• MD30465 $MA_AXIS_LANG_SUB_MASK, bit 0 = 1
Time that the subprogram is called
•
M40
The time of the call cannot be set. The replacement subprogram is always called at the block start.
•
M41
...
M45
The call time depends on the configured output behavior of the auxiliary function to the PLC (see below
MD22080):
- Output before or during motion: Subprogram call at the start of the block.
- Output after motion: Subprogram call at the end of the block
MD22080 $MC_AUXFU_PREDEF_SPEC[12 ... 16] (output behavior for
M41
...
M45
)
System variable to transfer information
The replacement subroutine is provided with all of the information relevant to the functions programmed in the
block via system variables (see Chapter "System variable [Page 652]"). The data refer exclusively to the block, in
which the function to be replaced has been programmed.
Bit
Value Meaning
5
1
Output of the auxiliary function before the motion
6
1
Output of the auxiliary function during the motion
7
1
Output of the auxiliary function after the motion
