Number of continuous paths
The number of continuous paths varies depending on the operation of the special auxiliary
relay M9015.
When the M9015 is OFF
While an interpolation operation is performed, preparation for interpolation control for the next
process is performed. Accordingly, there is no restriction in the number of continuous paths.
However, if there is a short-time path as follows, the next process cannot be read in advance
and the machine may temporarily stop its operation at this short-time path.
•
Path whose travel time is 50 ms or less.
• Path whose travel time is the interpolation time constant or less.
When the M9015 is ON
For up to 30 continuous paths, preparation for interpolation control is preliminarily performed
before the continuous paths are started. Accordingly, the machine never stops its operation if
any short-time path is present. However, at the 31st path, the machine stops its operation tem-
porarily, then starts the next continuous path.
When the number of continuous paths between the RPT and the RPE is 30 or less, repetitious
operations are also continuously performed. For most operations, setting M9015 OFF is usual.
The flag M9015 is not defined in FX
2N
-10GM. In this case, the actual operation is performed as
if M9015 is turned OFF.
