MP_syncGear
Synchronization of function with the NC if the gear speed
changes
Format: Selection menu
Selection: SYNC_EXEC
The function is synchronized with program run. The output of
movement by the interpolator is stopped; then the function is
executed.
Please note:
After this function has been executed, the look-ahead
calculation continues using the position values that were active
before execution of the function. This setting is not suitable for
M functions executing PLC positioning movements, for
example.
SYNC_CALC
The function is synchronized with program calculation. The
interpretation of the NC program is stopped and the path is
calculated internally; then the function is executed. The M
function is completely executed. After successful execution has
been acknowledged, calculation continues with new position
values.
ASYNC
The function is output without synchronization.
If the parameter is missing, synchronization is as given by the
parameter MP_sync.
Default: No value, parameter optional
Access: LEVEL3
Reaction: RESET
