Description:
With gantry axes, the difference between the position actual values of the
leading and synchronized axes is continuously monitored. MD37120
$MA_GANTRY_POS_TOL_ERROR defines the maximum permissible deviation in posi-
tion actual value between the synchronized axis and the leading axis in the
gantry axis grouping. Violation of this limit value is monitored only if the
gantry axis grouping is already synchronized (NC/PLC interface signal DB390x
DBX5005.5 (Gantry grouping is synchronized) = 1); otherwise the value set in
MD37130 $MA_GANTRY_POS_TOL_REF is used.
When this limit value is exceeded, alarm 10653 "Error limit exceeded" is out-
put. The gantry axes are immediately stopped internally in the control to
prevent any damage to the machine.
In addition, the NC/PLC interface signal DB390x DBX5005.2 (Gantry trip limit
exceeded) to the PLC is set to "1".
Special cases:
Alarm 10653 "Error limit exceeded" in response to violation of the gantry
trip limit.
