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 with the following exceptions. The exceptions include axial F value, M and S
value.
An axial F value is entered via the M, S, F distributor 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 if one or both values requires processing.
