◎ The main power supply (24VDC) must be able to provide continuous

operating current (see detailed specifications in Chapter 4) and

Peak current higher than 50% in 250us short cycle. Most types of lasers have a current loss of less than 10A, so their peak current loss is less than 14A.

◎ The power supply should maintain a stable voltage and be within the specified

range (see Chapter 4 for detailed specifications). If the up and down fluctuations of the power supply voltage exceed the specification range, the laser operation will be unstable. Please pay attention to the transient load variation rate of the power supply and choose an appropriate power supply type.

◎ When the main power of the laser is connected, the voltage drop (especially

the peak current loss) caused by the length and cross section of the laser’s own power cord can be ignored.

◎ The 24VDC main power supply must have a floating output, and its return line

can only be connected to the laser power line (blue). Incorrect connection may cause current loops to fail.

◎ The laser ground (DB25 Pin10-15,24) and the laser 24VDC power return

line (blue line) are connected to the inside of the laser module, and the external interface of the laser module is not allowed to be connected.

◎ The common ground inside the module is connected to the laser case through

a 470 ohm resistor and a 47nF capacitor in parallel. This network is used to balance the voltage difference between the ground and the laser case.

◎ According to the design, the ground of the control card may be connected to

the ground; otherwise, the ground of the control circuit is floating, indicating that the blue and yellow-green wires of the 24VDC power cable of the laser are not connected (see the red dotted line in the electrical connection diagram in this chapter for details) .

LHNormal Operation
HHMO Alarm
  1. Pin 18 is the Master Oscillator (MO) signal. The MO should be switched ON at least 5ms earlier than the Booster (BS) is switched ON. Once the MO is

switched ON, the laser starts to consume more electrical power.

  1. Pin 19 is the Booster control input. HIGH means switching the BS on and

LOW means switching it OFF. The laser starts to emit light within specified delay

time after the pin 19 is set HIGH and stops emitting when the pin 19 is set LOW.

Q-SWITCHED PULSED FIBER LASERS (MFP 5W-70W)

CAUTION :

◎ The MO should be switched ON at least 5ms earlier than the BS is switched ON. The laser does not start to emit if you switch the BS ON while the MO is LOW/OFF.

◎ If the MO is switched ON later than the BS is switched ON, the laser will emit about 1ms later than the switching of the MO. It is abnormal operation which should be avoid and not listed in the user guide. The BS switches ON simultaneously with the rising edge of the signal applied to the pin 19.

(6)Pin 20 is the Synchronization input. Pulse train with a repetition rate (PRR)

within specified operating range should be applied to the pin 20 (refer to the optical specification for PRR limits). The laser emits pulses simultaneously with the rising edge of the signal.

CAUTION:

◎ If the PRR is out of the specified range (or no PRR signal is supplied) the

laser safety circuit will substitute the missing pulses or limit the PRR.

◎ The laser emission is not allowed simultaneously with the guide laser. The BS is blocked internally during the guide laser operation. If pin 19 is set HIGH but the guide laser is on, the laser will not emit light, unless the guide laser is switched OFF. The MO is able to be switched ON or OFF during the guide laser is ON.

(7)Pin 23 is the “Emergency stop” input. It should be set to HIGH for normal operation. In case of dropping this pin to LOW state (even for a short period of

time), the laser automatically switches OFF (similar to the state when both MO and BS are OFF). It is necessary to drop both MO and BS to LOW (if they were HIGH) before restarting the laser.

Laser Operation

1. Steps

All control pins are TTL compatible, unless otherwise noted in the pin description. For the interface designs level ranges of the TTL standard should be taken into consideration.

  1. Remove the protective cap from the laser output head;
  2. Connect the control system with the laser DB25 pin interface. For the pins to be used, refer to 5.2.2 Digital Control Interface (DB-25) Function Description;
  3. Recommended initial state of control needle:

Pin18,19, pin is low

Pin20 repetition frequency is within the specified range

  1. Connect the 24VDC power supply to the laser power cable (+ 24V corresponds to red, the ground wire is connected to yellow, and the negative pole is connected to the black wire);
  2. After the laser is powered by 24VDC, it can be operated.

CAUTION:

◎ Please allow 24VDC main power before initializing the control signal.

  1. Set the emergency stop input (Pin23) to H level;
  2. Set the desired power from Pin1 ~ 8;
  3. Set Pin18 to H level and turn on MO;
  4. Wait for 5ms;
  5. Fast modulation of the laser by Pin19. Enter the H / L level to control the laser on and off. The rise / fall time of the laser switch has been limited (see Chapter 4 for detailed specifications). The speed of modulation cannot be faster than the sum of rise and fall times. Typical rise / fall time is 250us, and its modulation period should be greater than 500us (corresponding frequency is 2kHz);
  6. After completing the operation of the laser switch and waiting for the next task, if the time exceeds 20ms, it is recommended to turn off the MO, which will reduce power consumption, extend the life of the MO, and avoid the residual power output of the MO;
  7. Turn off BS and MO after completing a task (Pin18 and Pin19 are set to L level)
  8. Disconnect the 24VDC power supply.

2. Job characteristics

  1. During laser operation, PRR can be changed through Pin20. When changing the PRR, please note that the time between two adjacent rising edges must not be greater than the cycle time of the lowest PRR frequency. For a laser with a minimum repetition frequency of 20kHz, it should not be greater than 50us. Otherwise, the protection circuit will automatically add missing pulses. If the PRR is greater than the specified maximum repetition frequency, the protection circuit limits it to the maximum value.
  2. It is allowed to change the power settings of Pin1 ~ 8 during laser operation and store it in the laser. The laser will respond to the changed power setting during the specified rise time.
  3. If Pin18 is at H level and Pin19 is at L level, there will be laser output below 20mW working wavelength.
  4. If the temperature of the laser module exceeds + 45 ° C, the laser will automatically turn off, and at the same time at Pin16 and

Pin21 outputs the corresponding alarm signal. If the temperature drops below

+ 45 ° C, the laser will not automatically resume working, and keep the alarm signal unchanged, restart the operation.

1No laserPower supply
  1. Check whether the power supply wiring of the laser is correct, whether + 24V and GND are reversed, and whether the ground wire is grounded.
  2. Whether the power supply of the laser is normal. Check whether the power supply meets the actual power supply requirements under no-load and loaded

(connected to the laser) state.

Board
  1. Whether the signals of PIN18 and PIN19 are normal.
  2. Whether the power supply of the marking card is normal and the signal of the control laser is normal (see the definition of DB25 port in the manual for details).
emergency switch5. Check whether the emergency stop switch (PIN23 pin) of the device is normal (the signal is high when the

laser is working).

Marking software
  1. Whether the software settings are correct (see software settings for details).
  2. Use the software laser test function to observe if there is a light spot.
  3. Use the debugging software to test the laser and

observe the parameters.

DB25

signal

  1. Indicate whether the optical signal is in the low state in the marking state. If in the marking state, the guide light signal is low level (PIN22 pin is “0” level), if the guide light signal is high level (“1” level). The laser is the priority output guide light.
  2. Check whether the wiring of the DB25 pin serial port of the laser is correctly wired according to the wiring

definition.

Red light

confirmation

11. If the red light signal is high, the red light output will be given priority. (If it is a built-in red laser, you can

judge whether the laser light path is normal by detecting

whether there is red light output).

Isolator12. Confirm whether the light spot of the isolator is

normal (the light spot is round and there is no dark spot).
