Today, I will share with you some solutions to solve the failure of the laser cutting machine, so that you can better understand the running status of the machine during use, find problems in time, and avoid adverse effects on your normal production.
When the system sends out the analog quantity and detects that the encoder signal has no change, this alarm will be generated. The reasons for this alarm include:
The line is in poor contact, the analog signal is not sent to the servo, or the zero-speed clamp signal is always in effect, or the feedback signal of the encoder is not correctly connected to the height controller.
This alarm will be generated when the system detects that the difference between the feedback position and the target position is too large. When this alarm occurs, it generally means that the servo system cannot follow the position loop command of the height controller normally. The reasons for the laser cutting machine brand to generate this alarm include: the encoder direction is reversed. The position loop of the system does not form negative feedback. At this time, parameters need to be modified; the encoder feedback is abnormal due to wiring, interference, etc.; the Z-axis is mechanically stuck, and the torque of the system increases instantaneously, but the position is not in place in time.
