Today, we will share some solutions to the problems of the laser cutting machine, so that you can know more about the running state of the machine during use, find problems in time, and avoid adverse effects on your normal production.

Common faults of laser cutting machine:

1. No response from encoder

This alarm will be generated when the system sends analog quantity and detects no change in encoder signal. The causes of this alarm include:

The line has poor contact, the analog signal has not been sent to the servo, or the zero speed clamping signal has been in effect, or the feedback signal of the encoder has not been correctly connected back to the height adjuster.

2. Excessive position deviation

When the system detects that the difference between the feedback position and the target position is too large, the alarm will be generated. This alarm generally indicates that the servo system cannot follow the position loop command of the height adjuster normally. The causes of this alarm include:

The encoder is in the opposite direction. The position loop of the system does not form a negative feedback. In this case, you need to modify the parameters; The encoder feedback is abnormal due to wiring and interference; The Z-axis is mechanically jammed, and the torque of the system increases instantaneously, but the position is not in place in time.

When the system gives an alarm, turn off the power supply in time for troubleshooting. If the operator is unable to solve the problem, you can contact the manufacturer. Longtai has special after-sales service and professional technicians to provide technical support.
