*1. The performance improvement applies only to an NJ301-[][][][] CPU Unit.
       The maximum number of variables with a Retain attributes for the NJ501-[][][][] is 10,000.
*2. This is the total for all axis types.
*3. The performance improvement applies only to an NJ301-[][][][] CPU Unit.
       The maximum numbers of controlled axes for the NJ501-[][][][] are as follows:
       NJ501-1500: 64 axes, NJ501-1400: 32 axes, and NJ501-1300: 16 axes
*4. There is no change in the maximum number of used real axes.
*5. The performance improvement applies only to an NJ301-[][][][] CPU Unit.
       The maximum numbers of axes for single-axis control for the
       NJ501-[][][][] are as follows:
       NJ501-1500: 64 axes, NJ501-1400: 32 axes, and NJ501-1300: 16 axes
*6. Here, pps means “packets per second” and indicates the number of packets that can be processed in one second.
*7. The performance improvement applies only to an NJ301-[][][][] CPU Unit.
       You can use 500, 1,000, 2,000 or 4,000 μs communications cycle with an NJ501-[][][][] CPU Unit, and
       1,000, 2,000 or 4,000 μs communications cycle with an NJ101-[][][][] CPU Unit.
