4.11 Laser Power Control Interface LP1~LP6
This control system has six independent and adjustable digital laser power control
interfaces. Signals of the six interfaces are similar and the first digital interface (LP1) is
hereby exampled:
Pin
Symbols
Definitions
1
GND
Power ground (output)
2
L-ON1
Laser-enabled control interface
1. When the laser is the RF laser, this pin will not be used;
2. When the laser is a glass tube, if the used laser is outputted in
the low-level form, this pin will be connected with the laser power
enable end and used to control the ON/Off of laser.
3
LPWM1
Power control interface of laser/laser tube
1. When the laser is the RF laser, this pin will be connected with
the laser RF-PWM end;
2. When the laser is a glass tube, this pin will be connected with
the laser power PWM end and used to control the power of the
laser.
4
WP1
The input port of water protector for the first laser power source.
When the water protector 1 is enabled, the mainboard will detect
the input port of water protector 1. If this port is of low level, it will
be deemed normal; if this port is of high level, the mainboard will
forcibly close the laser to suspend the work in progress and the
system will warn. If the water protector 1 is not enabled, the
mainboard will not detect the input port of water protector 1 and so
the water protector 1 can be unconnected.
Water protection input must be 24V logic level.
5
L-AN1
The analog signals for Laser Power. If Glass Tube is used, this pin
is recommended to control the power of the Laser.
Please correctly select the laser type in the factory parameters.
