4. REPLACEMENT FROM A-MOTION TO QN-MOTION
6.2.2 Restrictions on the number of blocks and total points in the refresh setting
In Q-Motion, an automatic refresh function is one of the specifications added from A-Motion.
The number of blocks for the automatic refresh is limited to 4 blocks in Q173CPUN/Q172CPUN.
6.2.3 Timer counter
T (Timer device) and C (Counter device) can be used in A-Motion, but they cannot be used in Q-Motion.
When T and C are used on the motion SFC side, use the TIME instruction as an alternative method.
6.2.4 Parameter block
Since the error check function is improved in Q-Motion, errors and warnings will be displayed in the
parameter in which errors and warnings were not displayed in A-Motion after the replacement. Correct the
errors according to the content of the errors and warnings.
Example) A-Motion
• CPU module is changed from A-Motion to Q-Motion using MT2
• Error contents and measures
In the above case, set the sudden stop deceleration time to be equal to the deceleration time setting
value (500ms or shorter).
Note that the error check becomes stricter than before the replacement as the above case.
