On the controller, only one limit switch is needed. The limit is installed on the negative direction of
the axis. The protection of motion is by the soft limit.
The polarity can be set according to the limit switch type, such as PNP or NPN. And there is a led
indicator on the controller can show the limit is triggered or not.
This port is compatible with 5V, 12V or 24V.
4.8 X, Y, U axis interface AXIS_X, AXIS_Y, AXIS_U
The four motion axis interfaces are the same, taking the X axis interface AXIS_X as an example:

PUL
Pulse signal terminal (TTL)

+5V
5V power supply (output, only for driver common
positive connection)
Prompt
The pulse signal and direction signal are both OC output, so the
controller and motor driver must use the common anode connection
method. Common cathode and differential connection methods are not
supported.

LPWM
Laser machine/laser tube power control interface
1. If it is the RF laser, this pin is connected to the laser
RF-PWM to control laser power.
2.If it is the glass tube
，
this pin is connected to the PWM of
laser power to control laser power.

WP
It is the first laser power supply water protection status input
port. When water protection 1 is enabled, the controller will
detect the water protection 1 input port, if the port is in low
voltage, it is normal. If it is in high voltage, the controller will
forcibly turn off the laser, and the processing work will Pause
and the system will alarm. If the water protection 1 is not
enabled, the controller does not detect the water protection 1
input port. The user doesn’t need to connect the water
