Appendix 9 Connection Example of Servo Amplifier
*1 Be sure to use the class-D grounding method (grounding resistance: 100 or less).
*2 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.
*3 To detect absolute positions, connect this line to the CPU module.
*4 Set the command pulse input form (PA13) of the servo amplifier MR-J3A to "0010" (negative logic, forward rotation pulse train, reverse
rotation pulse train).
*5 Refer to Page 918 FX5S CPU module.
