9 OPERATION FOR MOTION SFC AND PARAMETER
However, when the timing of axis 1 moving from 359.99999[degree] to 0[degree]
coincides with the timing of the interrupt execution processing in the middle of
[G1] processing in Motion SFC normal task processing, an unintended operation
may occur.

When using the device whose value changes by the Motion operation cycle in a
conditional expression, store the value to a device and make the program
compare values as shown below.
