The cable that connects the controller and the panel is supplied as an accessory to customer.
Please connect the controller and the panel correctly with this cable.
4.3 U-disk Port
There is a USB port named U-disk on the controller. It is compatible with U stick and can read
and write the U stick.
4.4 PC-USB interface
PC-USB is a communication port that can build up the communication between the controller
and the computer. It supports USB2.0 protocol.

Aux.Air
Dedicated output. When auxiliary air control is enabled, this
port outputs a control signal to control the valve or other
relay to release auxiliary air. This port is multiplexed with
pen control signal. When auxiliary air control is disabled, this
port is assigned as pen control.
The output type is open collector.
The output can be set to be synchronized with laser or
synchronized with work.

Caution
This control system uses a single 24V power supply. In order to leave a
certain margin, it is recommended to choose a power supply of 24V / 2A
or more. At the same time, the control system is compatible with 36V
power supply, that is, the driver's 36V power can be directly connected to
the main power interface of the control system, but this is not
recommended

IntLock
Dedicated input, protection signal input. If the machine needs
to be protected in a specific state (such as cover open), the
alarm signal is input to this port. This port can be enabled
and disabled. When this port is disabled, this signal is
neglected by the controller. If this port is enabled, the
machine is protected when the input is in high voltage or the
port is float. Once the alarm triggered, motion will be stopped
and the laser is switched off synchronously.

Ex-Run
Dedicated input. Extern start input. Usually for foot control
switch start the machine. Low level is valid.
When system is idle, if a low level signal is sent to this port,
machine will be start. If the machine is working, a low level
signal is sent to this port, machine will be stopped. Send
again, machine will go on working.

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.

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

Water protection input must use 24V voltage input
5
L-AN
Laser power analog signal output. For glass tube laser power
supply, it is recommended to use this pin for power signal.
Prompt
Please select the correct laser type in the factory parameter settings.
When a glass laser tube is used, and the control signal cable is very long
from the controller to the laser power, if L-AN is for the power control, the
long cable will cause interference and make the laser power unstable. So
for this situation, PWM signal can replace the L-AN to control the glass
tube’s power. And decrease the interference.
