The spacing from axle X1+ and X1 to max. coordinate

5V Power positive (output)

The spacing polarity is optional, that is to say, when the motion axle reaches the spacing

position, it will trigger a low-level signal so as to make the corresponding LED (under the cover) light;

when the motion axle leaves the spacing position, it will trigger a high-level signal or disconnect the

spacing signal so as to make the spacing indicator go out, but when it leaves the spacing, the

corresponding indicator will light and the spacing polarity become positive. The mistaken setting of

spacing polarity will result that the spacing can’t be detected when the system is reset so as to lead

to the collision of axles.

Prompt

1.All axis limit input port is compatible with 5V /12V/24V logic level input

2.On the limit signal terminal, the sixth pin of X1/Y1-Lim and the sixth pin of

Z1/U1-Lim are both +5V, while the sixth pin of X2/Y2-Lim and the sixth pin of

Z2/U2-Lim are both +24V
