10.1.4 Actions

Function
In each synchronized action, you can program one or
more actions. All actions programmed in a block are
started in the same interpolation cycle.
In SW 5 and higher, actions can be used with a G
code for the action/technology cycle. This G code
specifies another G code from the one set for the
condition for all actions in the block and technology
cycles if necessary. If there are technology cycles in
the action part, then after completion of the
technology cycle the G code continues to apply
modally for all subsequent actions until the next G
code.
Only a G code from the G code group (G70, G71,
G700, G710) may be programmed.
Possible actions:
• Assign variables
• Write setting data
• Set control parameters
• DELDTG: Delete fast distance-to-go
• RDISABLE: Set read-in disable
• Output M, S and H auxiliary functions
• STOPREOF: Cancel preprocessing stop
• FTOC: Online tool offset
• Definition of evaluation functions (polynomials)
• SYNFCT: Activate evaluation functions: AC
control
• Switchover between several feedrates in a
programmed block depending on binary and
analog signals
• Feedrate overrides
• Start/position/stop positioning axes (POS) and
spindles (SPOS)
• PRESETON: Set actual value
• Activate or deactivate coupled-axis
motion/leading value coupling
