Description:
Value > 0
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 initiate 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 violation 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.
