How To Solve Alarm Information of Raytools Laser Cutting Head

Time：2022-8-9

The ETC-F100 is a focus adjuster controller designed for the laser cutting application by ECAT Automation, which can automatically adjust the focus of auto-focus laser head of BeamTool. ETCF100 can accurately adjust the position of the laser focus by the accuracy of 0.01mm. Today we will talk about some alarm information generated by ETC-F100 and how to solve them.

1.Upper and lower limit alarm

This alarm is generated when the system detects a sensor signal of the Z-axis upper limit or lower limit. If not meet the requirements, please reset the sensor position. If this alarm is always displayed, check:

  • Limit signal is not connected to the ETC-F100
  • Limit the sensor is obscured by unknown objects
  • Limit sensor installed improperly (this possibility is extremely small)
  • The limit signal is disturbed. At this time, the corresponding limit signal may flicker in the function test, especially after the motor is enabled. The ETC-F100 and the 24VDC limit signal can be independently powered A power filter is needed for the 220V AC of the Servo driver, and to ensure that the ground wire grounding well

2. “Zero Returning”Alarm

After the system is powered off and restarted, the controller needs to go back to zero to establish a reference coordinate system. If there is no back to zero, the panel will prompt ” Zero returning “，It can be solved by the following methods:

  • Perform a zero return operation through the ETC-F100
  • Select “Yes” and save it in the “power-on Reset”, and it will automatically return to zero after power-on again
  • High level can be input through “Zero returning” interface to realize backing to zero

3. “Exceeding z-axis stroke”Alarm

This alarm is generated when the actual Z-axis coordinate exceeds the Z-axis travel. When this alarm occurs, please note:

  • Z-axis travel setting is appropriate
  • Whether the location of dial overtravel

4. “Servo Alarm”

Under normal circumstances, when the drive alarm, “Servo Alarm”will be displayed by ETC-F100. If the drive is normal, and the ETC-F100 displays the “Servo Alarm”, it may be caused by the following conditions:

  • Servo driver wiring is incorrect
  • External interference
