POLFMASK / POLFMLIN interactions
The last data entered for a specific axis in one of the two instructions applies. For example:
N200 POLFLIN(X, Y, Z)
...
N300 POLFMASK(Z)
N500 POLFMLIN(X, Z)
Part program start
The positions programmed with POLF and the activation by POLFMASK or POLFMLIN are
deleted when the parts program is started. This means that the user
values for POLF and the selected axes (POLFMASK, POLFMLIN) in each parts program.
Examples
Application examples for parameterizing with several axes and incremental programming
can be found in Chapter "Examples", "ESR".
2.7.6 Possible trigger sources
The trigger sources must be distinguished by evaluating the specified system variables. Any
system variables that can be read in synchronized actions are available as error sources.
For example:
• Digital inputs/outputs ($A_IN, $A_OUT)
• Synchronous traverse deviations ($VA_EG_SYNCDIFF)
• Channel status ($AC_STAT) ...
The drive states can be read in $AA_ESR_STAT:
Bit 0: Generator operation initiated
Bit 1: Retraction initiated
Bit 2: Extended stop is triggered

The following error sources are possible for starting "Extended stop and retract":
