Description:
With gantry axes, the difference between the position actual values of the
leading and synchronized axes is constantly monitored.
MD37110 $MA_GANTRY_POS_TOL_WARNING is used to define a limit value for the
position actual value difference; when the limit is exceeded, warning 10652
"Warning limit exceeded" is output. However, the gantry axes are not stopped
internally in the control. The warning threshold must therefore be selected
so that the machine can withstand the position actual value deviation between
the gantry axes without sustaining mechanical damage.
Furthermore, the NC/PLC interface signal DB390x DBX5005.3 (Gantry warning
limit exceeded) to the PLC is set to "1". The PLC user program can thus ini-
tiate the necessary measures (e.g. program interruption at block end) when
the warning limit is exceeded.
As soon as the current position actual value difference has dropped below the
warning limit again, the message is canceled and the interface signal "Gantry
warning limit exceeded" is reset.
Effect of the gantry warning limit on the gantry synchronization process:
The position actual value difference between the leading and synchronized
axes is determined during gantry synchronization. If the deviation is less
than the gantry warning limit, the synchronizing motion of the gantry axes is
automatically started internally in the control.
Otherwise the synchronizing motion has to be initiated via the PLC interface
(interface signal DB380x DBX5005.4 (Start gantry synchronization process))
Value = 0
The setting MD37110 $MA_GANTRY_POS_TOL_WARNING = 0 is the monitoring for vio-
lation of the warning limit deactivated.
The gantry synchronization is not initiated internally in the control.
Special cases:
Alarm 10652 "Warning limit exceeded" in response to violation of the gantry
warning limit.
