CONTROL SIGNALS

Command signal

The modulated Command signal applied to Series 48 lasers has three parameters: signal amplitude, base

frequency, and PWM duty cycle. By changing these parameters, you can command the beam to perform

a variety of marking, cutting, welding, or drilling operations.
The first Command signal parameter, signal amplitude, is either logic low—corresponding to laser beam

off, or logic high—corresponding to beam on. The laser off voltage, typically 0 V, can range from 0.0 V to

+0.5 VDC while the laser on voltage, typically 5 V, can range from +3.5 V to 10.0 VDC.
Base frequency, the second parameter, is the rate at which the amplitude is switched between its low and

high logic states. The standard base frequency is 5 kHz, which has a period of 200

μ

s. Maximum PWM

frequency is 20 kHz.
The third Command signal parameter, PWM duty cycle, is the percentage of the period that the Command

signal is high. If the Command signal’s amplitude (at 5 kHz) is high for 100

μ

s and low for 100

μ

s, it has a

50% duty cycle; if the amplitude is high for 190

μ

s and low for 10

μ

s, it has a 95% duty cycle. The following

figure illustrates Command signal parameters while the following table lists PWM Command signal

specifications.

Table 4-5 PWM Command signal specifications.

Figure 4-6 PWM Command signal waveform.

Warning: Serious Personal Injury

Always use shielded cable when connecting your PWM Command signal source to PWM Input / PWM

Return inputs. In electrically noisy environments, long lengths of unshielded wire act like an antenna

and may generate enough voltage to trigger uncommanded lasing.
