Set tool offset to active immediately

You can specify that the tool offset is to take effect immediately in display machine data

The part program is in the "Reset" or "Stop" state.
To ensure that the tool offset is not reset on "Reset", the channel-specific machine data
MD20110 $MC_RESET_MODE_MASK bit 0 = reset mode must be appropriately set.

more than one offset data set.
