# Classification of clamp position offset data

Clamp position offsets can be defined in different groups in the clamp position offset data list. The required clamp position offset group can be loaded by selecting the clamp position offset index before program start-up. Each clamp position offset group contains the clamp position offset data for all path axes and is generally referred to below as clamp position offset.

The clamp position offset data is included in the coordinates of all path axes at program start-up. The axis index corresponds to the channel-internal axis index. The initial axis configuration of the NC channel is defines in the channel parameters
[CHAN// Section: Configuration of path axes].

Value ranges of parameters may also be defined by stating a limit resulting from data width, e.g. MAX(UNS32), etc.
