  • Page 12: Getting Started

    Introduction The v40 laser is a small-footprint laser from NOVANTA featuring high power and excellent beam quality. The circular beam provides more accurate cutting and faster processing speeds than competing technologies. With an integrated RF power supply, meaning no external RF cables, the compact laser housing mounts easily to flatbed cutters, robotic arms, or gantry systems making integration into your production line simple and fast.

    FASTENING FROM ABOVE PAGE Fastening from above To fasten to a mounting surface from above, perform the following steps: Refer to the appropriate outline and mounting drawing for dimensions and then drill and tap three 1/4–20 UNC holes into your mounting surface. These hole locations should correspond to the two slots labeled “A”...

  • Page 17: Connecting

    Control connections Water-cooled connections If your v40 laser is fan-cooled, then skip to the Electrical connections section. Read Guidelines for cutting and installing tubing before installing any cooling tubing and then make sure to connect the cooling system exactly as described for your particular laser.
  • Page 18 Avoid glycol-based additives because they reduce the coolant’s heat capacity and high concentrations may affect power stability. For NOVANTA lasers, the minimum coolant setpoint is 18 °C (64 °F) so glycol is not necessary unless the chiller is subjected to freezing temperatures. In applications where biocides containing chlorides are used, concentrations should not exceed 25 parts per million (PPM).
  • Page 19 WATER-COOLED CONNECTIONS PAGE • Increase coolant flow by an additional 1.0 GPM (3.8 lpm). Do not exceed a coolant pressure of 60 PSI (4.1 bar). • Air-condition the room or the enclosure containing the laser. • Install a dehumidifier to reduce the humidity of the enclosure containing the laser. Table 1-2 provides dew point temperatures for a range of air temperature and relative humidity values.

    Cut and connect a length of tubing to fit between the chiller’s Outlet port and the upper WATER IN port on the rear of the v40 laser. 2. Cut and connect a length of tubing to fit between the lower WATER OUT port on the rear of the laser and the chiller’s Inlet port.

  • Page 21: Oem Air-Cooled Connections (Sab Models)

    Because v40 OEM air-cooled lasers are shipped without cooling fans, customers must provide some type of air cooling to prevent overheating. NOVANTA recommends an airflow of at least 140 cubic feet per minute for each of the two required fans. Figure 1-5 illustrates the fan placement necessary to keep the laser’s heat sink temperature below 45 °C.

  • Page 22: Figure 1-6 Rear-Mounted Cooling

    The cooling fan must supply at least 300 CFM in order to keep laser and RF heat sink temperatures below 45 °C (113 °F). Note that rear-cooled v40 lasers may experience some performance degradation when compared to the typical side-mounted cooling configuration. Because of the heat generated by ’s integrated RF circuitry, establishing significant airflow evenly over the entire surface area of the combined laser/RF chassis is vitally important to the performance and longevity of the laser.

  • Page 23: Electrical Connections

    DC power supply v40 lasers require a DC power supply that provides 30 VDC at 24 A maximum. We recommend the NOVANTA DC-5 DC power supply that supplies 30 VDC at 33 A. AC input requirements for the DC-5 are 90–132 VAC (low range) or 175–264 VAC (high range), single phase (1ø), 15 A max, 47–440 Hz.
  • Page 24 ELECTRICAL CONNECTIONS PAGE Important Note: The negative (–) side of the DC input to the laser is internally connected so that the laser chassis serves as DC power ground. You should isolate the laser’s DC power supply so that the only grounded connection is at the laser. Alternatively, you can mount the laser chassis on an insulating pad or film in order to electrically isolate the laser when other equipment is grounded to the laser’s DC power supply.

  • Page 25: Control Connections

    Control connections All control connections to the v40 laser are made through the 15-pin User I/O connector on v40’s rear panel. The User I/O port receives power commands from the NOVANTA’s UC-2000 Universal Laser Controller and also serves as the connection point for auxiliary signals between the laser and any parts handling, automation, or monitoring equipment.

  • Page 26: Laser Safety Introduction

    Failure to do so may damage the laser. In order for your v40 laser to properly operate, several input signals must be applied to the DB-15 User I/O connector before lasing is enabled. Remote Interlock (Pin 3) and Shutter Open Request (Pin 10) inputs must be powered before the laser will fire.

  • Page 43 Caution: Possible Equipment Damage Inlet cooling water temperature must always be maintained above the dew point to prevent condensation and water damage to your v40 laser. Important Note: If you have not yet operated your UC-2000 Universal Laser Controller, refer to the UC-2000 Laser Controller Operator’s Manual for setup and operation instructions before continuing.
  • Page 44 Important Note: Each time an OEM laser is powered up or a Keyswitch version is cycled OFF/ON, a five-second delay occurs between the time that RDY and/or SHT indicators illuminate and v40 is permitted to lase. Warning: Serious Personal Injury Because of phase differences, external tickle pulses may combine with the internally generated tickle signal causing the LASE LED to flicker during the transition from tickle to lasing.

  • Page 45: Without A Uc-2000 Controller

    WITHOUT A UC-2000 CONTROLLER PAGE Without a UC-2000 Controller If you have chosen not to use a UC-2000 to control the laser, follow the procedure below to verify the laser’s functionality. Although a tickle signal is not required, you will need to provide PWM Command signals to ’s User I/O connector.
  • Page 46 Starting your v40 laser v40 RDY and SHT LEDs denote separate control functions. Although the RDY lamp may light while the SHT LED is Off (Shutter Switch Closed or Shutter Open Request signal missing), no power is applied to the RF boards until both RDY and SHT indicators are illuminated.

  • Page 47: Technical Reference

    The optical resonator, in conjunction with the electrodes and the gas mixture, generates the laser beam. v40 optical resonators are comprised of four optical elements: a rear mirror, two turning mirrors, and an output window. These optical elements are fastened to the tube’s exterior and are exposed to its interior...

  • Page 48: Rf Power Supply

    Because of their smaller beam diameter, v40 lasers have significantly higher power densities than previous NOVANTA lasers. This means that even a small amount of contamination on the laser’s out- put window (or on any optic in the beam path) can absorb enough energy to damage the optic.

  • Page 49: Optical Setup

    OPTICAL SETUP PAGE Optical setup After selecting a laser for a CO2 laser processing system, the two most important elements to consider are: Delivery optics to transmit the beam to the work area; and (2) focusing optics to focus the beam onto the part or material to be processed.

  • Page 50: Controlling Laser Power

    Much of the information provided in this section describes the use of a NOVANTA UC-2000 Universal Laser Controller to provide PWM Command signals to the v40 laser. If using an alternate method of laser control, thoroughly review this section, controlling laser power, as well as the following section, User I/O connections, for an understanding of the signal requirements necessary to control lasers.

  • Page 51: Controlling Laser Power

    Controlling laser power Figure 4-3 Representative v40 waveforms v40 lasers are designed to operate at Command signal base frequencies up to 25 kHz; however, the choice of PWM frequency depends on the user’s specific application. In the majority of laser applications,...

  • Page 52: Figure 4-4 Pwm Command Signal Waveform

    The modulated Command signal applied between Pin 9, PWM Input, and Pin 1, PWM Return, of the User I/O connector on the v40 laser has three basic 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.

  • Page 53: Operating Modes

    PAGE V40’s User I/O PWM input consists of a high-speed PWM input LED with a forward voltage drop (Vf) of 1.5 VDC. The PWM input frequency can range from DC (0 Hz) to 25 kHz. Table 4-2 provides minimum, maximum, and nominal PWM signal specifications.
  • Page 54 To adjust output power, refer back to the Pulse width modulation (PWM) section for information about high frequency operation Important Note: NOVANTA lasers are designed for maximum performance at a 95% duty cycle. Increasing the maximum PWM percentage beyond 95% greatly increases the laser’s heat load with little or no corresponding increase in laser output power.

Important Note: See DB-9 connections later in this section for signal descriptions and pinouts of the SAB model’s side-mounted DB-9 connector.

  • Page 58: Figure 4-6 Auxiliary Power Supply Wiring

    PAGE Auxiliary DC power V40’s User I/O connector provides auxiliary DC power for driving external inputs or outputs connected to the User I/O port. Pin 4, +5 VDC Auxiliary Power, and Pin 5, +24 VDC Auxiliary Power, are protected by self-resetting fuses rated at 0.5 A. Pin 12, Auxiliary DC Power Ground, is connected to chassis ground while all other User I/O pins are floating with respect to chassis ground.
  • Page 59 PAGE Input signals A total of four user inputs allow control of v40 lasers. Remote Interlock, Shutter Open Request, and Remote Reset/Start Request inputs are optoisolated and bi-directional, allowing for positive or negative polarity signal inputs. These three signals also share a common return connection, Input Common, which is separate from chassis ground to completely isolate control signals for optimal EMI performance.

  • Page 69: Integrating Safety Features

    V40’s keyswitch, shutter, and remote interlock functions serve to enable or disable DC power to v40’s RF drive. Without power, the RF driver cannot supply PWM Command or tickle signals to the resonator, causing the CO2 gas to remain in a zero-energy state. V40 status indicators provide users with a quick visual indication of the laser’s operational status.

  • Page 70: Keyswitch Functions

    KEYSWITCH FUNCTIONS PAGE Keyswitch functions Keyswitch lasers After DC power-up or after a remote interlock fault, the Keyswitch must be toggled to reset the laser and enable the RDY LED, signaling that DC power is applied to the RF driver. Over temperature faults are reset by removing, then reapplying DC power after the laser has cooled.

  • Page 71: Shutter Functions

    SHT LED illuminates blue to indicate that DC power is applied to the RF driver. For v40 OEM and Keyswitch-equipped lasers in automated systems, the shutter function is provided by the Shutter Open Request signal via Pin 10 on the User I/O connector. To use this “remote shutter,” first place the Shutter Switch (if equipped) in the ON position.

    Laser faults v40 lasers version D and above (KFD, SAD, etc.) can indicate four specific fault conditions. In the event of a certain faults, the RDY LED on the laser will blink an error code, pause four seconds, and then repeat the error code.
  • Page 89 OEM lasers Warning: Serious Personal Injury On v40 OEM lasers, remote interlock (INT) faults are not latched. Clearing the fault condition re- enables the RDY indicator and the laser will fire after the five-second delay provided that the SHT indicator is lit and a PWM Command signal is applied. Because exposure to 10.6 μm CO2 laser radiation can inflict severe corneal injuries and seriously burn human tissue, the OEM or System Integrator must ensure that appropriate safeguards are in place to prevent unintended lasing.
  • Page 90 °C (air-cooled) and then cycle DC power to the laser. Once the RDY lamp is lit, lasing is possible after the five-second delay. Note: Over temperature faults are not latched on earlier OEM v40 lasers. Cool the laser until the TMP indicator changes from red to green. After the RDY lamp lights, lasing is possible after the five-second delay.
  • Page 91 PAGE Warning: Serious Personal Injury On v40 OEM lasers, remote interlock (INT) faults are not latched. Clearing the fault condition re- enables the RDY indicator and the laser will fire after the five-second delay provided that the SHT indicator is lit and a PWM Command signal is applied. Because exposure to 10.6 μm CO2 laser radiation can inflict severe corneal injuries and seriously burn human tissue, the OEM or System Integrator must ensure that appropriate safeguards are in place to prevent unintended lasing.
  • Page 92 Possible Causes: • The Shutter Switch (if equipped) is Closed. If your v40 laser is equipped with a Shutter Switch, slide the switch to the Open position. The SHT indicator will illuminate blue. • No voltage applied to Pin 10 (Shutter Open Request) on the User I/O connector.

  • Page 93: Beam Delivery Optics

    An over temperature condition has occurred. On earlier OEM lasers (v40 versions B and C), over temperature faults are not latched. This means if an over temperature condition occurs, the TMP indicator will turn red, the Over Temperature output will Close, the RDY light goes out, and lasing is disabled.
  • Page 94 If the focusing optic is pitted, it must be replaced immediately.
