Main axes

Significance
A main axis is an axis that is interpolated by the main run.
This interpolation can be started as follows:
• From synchronized actions
(as command axes due to an event via block-related, modal or static synchronized actions)
• From the PLC via special function blocks in the PLC basic program
(named as a concurrent positioning axis or a PLC axis)
• Via the setting data or from the part program
(as an asynchronous or block-synchronous oscillating axis)
Channel control
An axis interpolated by the main axis reacts in terms of:
• NC STOP
• Alarm handling
• Program control
• End of program
• RESET
Note
The response at the end of the program varies. The axis movement need not always be
completed and, therefore, may carry on beyond the end of the program.
