Cont. Signal name
High-speed simple program check: Enable coordinate posi-
A
tion check
[Function]
This signal enables the following check when NC reset is input during high-speed simple program check: difference check
for the workpiece coordinate position and command machine coordinate position at the beginning of the machining
program and at NC reset input.
[Operation]
If the following conditions are met, the workpiece coordinate position and command machine coordinate position at the
beginning of the machining program are compared with these positions at NC reset input: this signal is turned ON during
high-speed simple program check and NC reset is input while the "High-speed simple program check: Coordinate position
check ON" signal (X713) is ON.
If any difference is detected, an operation error occurs.
This check is performed only for the following axes: the axes for which workpiece coordinate position/command machine
coordinate position checks are enabled with parameters "#8226 work position check" and "#8227 machine position
check".
