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.
