Miscellaneous
Inapplicable interface signals
The following IS signals (PLC → NCK) have no effect for axes at endstop until deselected
(incl. traversing motion):
●
IS "Axis/spindle disable"
●
IS "Controller enable"
Actual position at fixed stop
System variable $AA_IM[x] can determine the actual position of the machine axis, e.g. for
test purposes after successful travel to fixed stop.
Combination with measuring function
"Measure with deletion of distancetogo" ("MEAS" command) and "Travel to fixed stop"
cannot be programmed at the same time in one block.
Contour monitoring
Axis-specific contour monitoring is not performed while "Travel to fixed stop" is active.
Selection for G64
In MD37060 FIXED_STOP_ACKN_MASK, bit 0 must be 0 (do not wait for PLC input signal
"Travel to fixed stop not activated"), since the selection of FXS may not initiate a motion
stop. If this bit is programmed, however, the alarm 20090 "Travel to fixed stop not possible -
check programming and axis data" is output.
