2.1.8 External Positioning (EXM)
! ! ! ! Outline
When executing the positioning command, once the external positioning (EXM) signal is
input, the next block is executed after moving the designated distance.
• The EXM command is only enabled for one axis
• Move the designated distance if the signal is not input.
• The external positioning signal is connected to the external latch input (connector
1CN, Pin 10) on the servo amplifier of the designated axis.
! ! ! ! Detailed Explanation
The designating method of the EXM command is shown as follows:
If a negative value is designated as the moving amount, the axis moves in a negative
direction after decelerating to a stop.
• Only the designated distance amount is executed during machine lock, ignoring the
external input signal.
• Movement continues for the designated distance if the signal is not input.
Important Points
(1) The external positioning signal is 1CN 10pin of the servo amplifier; connect it to the
external latch (/EXT).
(2) The external latch (/EXT) input signal is also used for the zero-point return using the
“Zero-point LS”. Therefore, be careful when using.
