*1 Be sure to use the class-D grounding method (grounding resistance: 100 Ω 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 I/O module are used in the connection example.
Inputs and outputs built into the CPU module are available in place of I/O module.
*5 Set the command pulse input form of the servo amplifier (PA13) MR-JNA to "211" (negative logic, signed pulse train, command input
pulse train filter: 200 Kpps or less).
