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:
– Interpolation point coordinates (I1, J1, K1)
– Interpolation parameters (I, J, K)
– Circle radius (CR)
● Pitch (G34, G35)
● Programmable work 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).
Note
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 is always read in the parameterized basic system.
