Selection of interpolation type
The interpolation type that should effective for G0 is adjusted with the following machine
data:
MD20730 $MC_G0_LINEAR_MODE (interpolation response in G0)
Value
0
1
The desired interpolation response in G0 can also be programmed via the two following part
program commands, independently of the default:
RTLIOF
RTLION
The currently set interpolation response of the path axes with G0 can be queried with system
variable $AA_G0MODE.
Note
In both interpolation types, rapid override is channel-specific.
11.3.3 Autonomous single-axis operations
Functionality
Single PLC axes, command axes started via static synchronized actions or asynchronous
reciprocating axes can be interpolated independently of the NCK. An axis/spindle
interpolated by the main run then reacts independently of the NC program with respect to:
● NC STOP
● Alarm handling
● Program control
● End of program
● RESET
