# Consider the master position in the slave

## Calculate the current master position at activation

The current position of the master can be considered in the tracking function in the slave. When the tracking function is activated, you can specify whether the current master position is transferred to the slave channel decoder (option SET_ZERO). If this option is selected, the master positions are saved in channel-specific variables. This can only be done when the slave channel is at standstill, i.e. not on the fly.

V.G.TRACK_CS.X/Y/Z/A/B/C

The master position in the slave can then be calculated individually by various NC commands (#TRACK CS ABS, G92, #CS, etc.).
