WORKING MECHANISM
The YDLIDAR G4 (hereafter referred to as G4) system has 3 working modes: idle mode, scan mode,
stop mode.
Idle mode: When G4 is powered on, the default mode is idle mode. In idle mode, the G4's
ranging unit does not work and the laser is not lit.
Scan mode: When G4 is in scanning mode, the ranging unit turns on the laser. When the G4
starts to work, it continuously samples the external environment and outputs it in real time after
background processing.
Stop mode: When G4 runs with an error, such as turning on the scanner, the laser is off, the
motor does not rotate, etc., G4 will automatically turn off the distance measuring unit and
feedback the error code.
