Fig. 2-6 PLC/NC channel interface
PLC/axis, spindle, drive signals
The axis-specific and spindle-specific signals are divided into the following groups:
• Shared axis/spindle signals
• Axis signals
• Spindle signals
• Drive signals
The signals are transferred cyclically at the start of OB 1, with the following exceptions:
Exceptions include:
MMC INC mode, axial F value, M/S value
.
An axial F value is entered via the M, S, F distributor of the basic program if it is transferred
to the PLC during the NC machining process.
The M and S value are also entered via the M, S, F distributor of the basic program if an S
value requires processing together with the corresponding M value (M03, M04, M05).
