Further information
G70/G71
With G70/G71 active, only the following geometric data is interpreted in the relevant
measuring system:
• Position data (X, Y, Z, ...)
• Circular-path programming:
-
-
-
• Pitch (G34, G35)
• Programmable zero offset (TRANS)
• Polar radius (RP)
Synchronized actions
If, in a synchronized action (condition component and/or action component) no explicit
measuring system is programmed (G70/G71/G700/G710), the measuring system which was
active in the channel at the point of execution will be applied to the synchronized action
(condition component and/or action component).
NOTICE
Read position data in synchronized actions
If a measuring system has not been explicitly programmed in the synchronized action
(condition component and/or action component) position data specified in units of length in
the synchronized action are always read in the parameterized basic system.
