Figure 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 transmitted cyclically at the start of OB1 with the following exceptions:
Exceptions include:
INC-Mode of HMI, 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).
