System Commissioning Manual
2.3.7 PWM Interface
There are 2 PWM pulse width modulation signals, which can be used to control the average power of the
fiber laser. The PWM signal supports 24V or 5V (manually adjusting), and the duty cycle is adjustable
from 0% to 100%.

2.3.8 Sensor Interface
There is a sensor interface circuit for laser head height adjustment. The output signal from the receiving
capacitor amplifier circuit is fed to the CPU through the conditioning circuit, and the interface is defined
as follows:
