PWM input signals if the “On” pulse is less than 100 μs in duration. At a constant 50% duty cycle, vi30/40 lasers typically reach 90–100% of full optical output when operated at a frequency of 5 kHz and reach 65–80% optical output at 7 kHz. The percentage of optical output increases as duty cycle increases (at a constant PWM frequency) or as PWM frequency decreases (at a constant duty cycle).

OPERATING MODES PAGE Continuous wave (CW) In some applications, such as high-speed marking or cutting, the time constant of the laser and the PWM modulation causes a series of dots that may be visible on the marking surface instead of a “clean” line. Operating the laser in CW mode will prevent this behavior from occurring.
User outputs indicate vi30/40 ready, lase, overtempt, and input voltage status. The OEM vi30/40’s PWM inputs are optoisolated; however, all other inputs and outputs operate using standard 5V logic levels (0V – logic low; 5V – logic high). Both inputs and outputs are ESD protected but are not optoisolated;...

COOLING PAGE Table 5-1 Required cleaning materials. Caution: Possible Equipment Damage Do not allow the nozzle of the air bulb to touch the optical surface. Any contact may damage the optic by scratching coatings on the optical surface. Do not use compressed shop air to blow contamination from the optic. Compressed air contains significant amounts of water and oil that form adsorbing films on the optical surface.
Status LEDs Three status LEDs on the rear of the OEM vi30 laser provide a visual indication of operating status. A green PWR LED illuminates when DC power is applied to the laser. The yellow RDY LED indicates that a Laser Enable signal has been applied and that, after a five-second delay, lasing will begin once a PWM Command signal is received.
Laser fault indications OEM vi30/40 lasers can indicate five specific fault conditions. In the event of certain faults, the RDY LED, PWR LED or both will blink an error code, pause 1/2 second, and then repeat the code. This sequence continues until the fault is corrected and the laser is reset by cycling DC power to the laser.
