Parameter

Variabel und per Kanalparametersatz zuweisbar sind die Adressbuchstaben zur Bezeichnung der numerischen Achsen. Normally the letters X, Y, Z are used to designate the 3 linear axes of a Cartesian spatial coordinate system. A, B, C are used to designate rotary axes (case-sensitive). According to DIN 66025, the second motion in parallel to the spatial coordinate system is specified by U, V, W.

Besides this simple option, axis designations may also consist of several characters (strings) (X_ACHSE, Y22, ZA3). To distinguish between an axis designation and a coordinate value, the "=" character is used, i.e. X1=120.345

The following sections in this programming manual mainly use the first case mentioned and often use address letters.
