following figure illustrates PWM Command signal parameters while the following table lists PWM signal
specifications
Figure 3-3 PWM Command signal waveform
The v30’s PWM input (on either the Interface A or Interface B connector) consists of a high-speed
optoisolator LED with a forward voltage drop (Vf) of 1.5 VDC. The PWM input frequency can range from
DC (0 Hz) to 100 kHz. Table 3-2 provides minimum, maximum, and nominal PWM signal specifications.

Operating modes
External control
In
addition to controlling the OEM v30 laser using a UC-2000 Universal Laser Controller, control of the
v30 externally, without a UC-2000, is also possible. The two primary elements of laser control are gating,
the ability to turn the laser on and off at the appropriate times, and power, the ability to control the
laser’s output energy. Both gating and power can be handled by a device such as a personal computer,
Programmable Logic Controller (PLC), or function generator capable of providing tickle pulses in
addition to sending PWM signals at the proper time (gating) and with the proper duty cycle (power).
Analog voltage or current control
Although OEM v30 lasers cannot be controlled directly by analog voltage or current signals, this type of
control is possible when using the UC-2000 Controller. The Controller is connected normally to the laser
