How to connect the footswitch of the laser marking card? How to control the footswitch?
First of all, how to connect the footswitch of the laser marking card?
The input port of a universal laser marker has two internal configurations.
1. an input port with an internal power supply.
This input port and the laser marker card are the common power source and are suitable for connecting normally open contacts of passive switches. In other words, a direct connection to the switch, as shown in the figure.
On the left is a footswitch. Although this port is connected to an optocoupler, it is not inherently isolated. This is because it is common for the switch and laser marker cards to use power. When the footswitch is closed, the light-emitting diode of the optocoupler lights up and the signal is transmitted to the inside of the laser marker card.
How is the footswitch connected to the laser marker card? How to set the footswitch inside the laser marking machine software?
Today, the fiber laser marking machine static marking refers to the object is placed under the laser head stationary, manually to trigger the corresponding button or device to achieve marking. The mouse and keyboard are the most basic triggering devices, triggering the mouse and keyboard need to be used by hand.
But in practice, the staff generally use their hands to replace the object to be marked, if the goods are replaced, and then to trigger the mouse, it will affect the work efficiency. So then we need to use the foot pedal, hands and feet can greatly improve efficiency, the following is the foot pedal connection and use tutorial.
Footswitch wiring instructions: marking card DB37's, pin 1 for the external trigger, pin 5 for pin 1 power supply, pin 6 for ground, note that you must give the power to pin 5 and pin 6, otherwise the footswitch can not work.
In addition, if you encounter the foot pedal, not marking (but the mouse click can be marked), please check the following points.
1, marking software using the footswitch must be marked with a small triangle symbol on the common toolbar, if you click the marking button on the status bar marking, the foot jump switch will not work.
2, the footswitch is bad, replace the footswitch.
3, the laser control card is bad. Footswitch signal voltage, the normal situation is marked and not marked have a 5V signal voltage.
4, the signal line between the board and the footswitch open circuit https://www.chineselaser.com/laser-galvo-controller/ |
