Precautions
• When changing the device assignment method, the changes are enabled by power ON of the Multiple CPU system, or by
reset.
• When using R64MTCPU in Q series Motion compatible device assignment, the devices for axis 33 to 64 use MELSEC iQ-
R Motion device assignment. Bear in mind that the regularity of MELSEC iQ-R Motion device assignment differs to that of Q
series Motion compatible device assignment.
• Performing "Motion CPU memory clear" from MT Developer2, or clearing "Backup RAM" with the "built-in memory clear" by
rotary switch returns the device assignment "Q series Motion compatible device assignment".
• When loading backup data to the Motion CPU with MT Developer2, the device assignment method of the Motion CPU
where backup data is being loaded and the backup data must be the same. If the device assignments methods are different
an error occurs and loading is not possible. Also, when the backup data does not support the device assignment method of
the Motion CPU, set the device assignment method of the Motion CPU to "Q series Motion compatible device assignment".
• Communication between MT Developer2 and the Motion CPU is not possible when the device assignment methods differ.
