CAUTION
● When changing data and operating status, and modifying program of the running programmable 
controller from an external device such as a personal computer connected to an intelligent function 
module, read relevant manuals carefully and ensure the safety before operation. Incorrect change or 
modification may cause system malfunction, damage to the machines, or accidents.
● Do not power off the programmable controller or reset the CPU module while the setting values in the 
buffer memory are being written to the flash ROM in the module. Doing so will make the data in the 
flash ROM and SD memory card undefined. The values need to be set in the buffer memory and 
written to the flash ROM and SD memory card again. Doing so also may cause malfunction or failure 
of the module.
● Note that when the reference axis speed is specified for interpolation operation, the speed of the 
partner axis (2nd, 3rd, or 4th axis) may exceed the speed limit value.
● Do not go near the machine during test operations or during operations such as teaching. Doing so 
may lead to injuries.
CAUTION
● When disposing of this product, treat it as industrial waste.
● When disposing of batteries, separate them from other wastes according to the local regulations. For 
details on battery regulations in EU member states, refer to the MELSEC iQ-R Module Configuration 
Manual.
CAUTION
● When transporting lithium batteries, follow the transportation regulations. For details on the regulated 
models, refer to the MELSEC iQ-R Module Configuration Manual.
● The halogens (such as fluorine, chlorine, bromine, and iodine), which are contained in a fumigant 
used for disinfection and pest control of wood packaging materials, may cause failure of the product. 
Prevent the entry of fumigant residues into the product or consider other methods (such as heat 
treatment) instead of fumigation. The disinfection and pest control measures must be applied to 
unprocessed raw wood.
