Axis Operating Flag
(n+16 bit 04)
6-5-59 Word n+16 Bit 05: Positioning Completed Flag (X-axis)
This flag is turned ON when the axis reaches its target position in a positioning
operation and the axis is within the in position range specified in the system
parameters. Use this flag as a condition to check when the target position has
been reached and the next function can be executed.
Once the axis enters the in position range of the target position and the Position-
ing Completed Flag is turned ON, the flag will remain ON until the next position-
ing operation is performed, even if the axis leaves the in position range.
The Positioning Completed Flag will be turned ON if the positioning operation is
interrupted before the target position is reached but the axis is within the in posi-
tion range.
In position checks are performed regularly during MPG operation and this flag
will be turned ON when the axis is within the in position range.
When a positioning operation is started, the Positioning Completed Flag will be
turned OFF at the same time that the Axis Operating Flag is turned ON.
The Positioning Completed Flags for the Y axes (bit 05 in words n+19) operate in
the same way.
