*1 Be sure to use the class-D grounding method (grounding resistance: 100  or less).
*2 Near-point signal (DOG)
Any input other than high-speed pulse input/output module can also be used.
*3 To ensure safety, use the forward rotation limit switch and the reverse rotation limit switch on both sides: the CPU module side and the
servo amplifier side.
Note that the limit switches on the CPU module side should be activated slightly earlier than the limit switches on the servo amplifier
side.
*4 To detect absolute positions, connect this line to the CPU module.
*5 I/O module are used in the connection example. Inputs built into the CPU module are available in place of I/O module.
*6 Set the command pulse input form (PA13) of the servo amplifier MR-J4A to "0210" (negative logic, forward rotation pulse train, reverse
rotation pulse train, command input pulse train filter: 500 kpps or less).
*7 Refer to Page 899 FX5U CPU module.
