*1 For the relationship between the total length, the wire diameter of transmission cables (DP, DN), and the transmission
cable supply current, refer to the following. On some slave modules with cables, the wire diameter of module-integrated
transmission cables (DP, DN) may be 0.75or less. However, they can be used without any problem, provided that the
diameter of the transmission cables (DP, DN) meets the requirement below.
