1.1.23Reset error
There may be the following reasons to cause the reset error：
When resetting, the laser head have no motion or the speed is too low and has caused a
timeout action. Please check the parameters of the distance controller.
The polarity of the motor is wrong. When resetting, the laser head move down to trigger
the down limit.
1.1.24Capacity fault
If the current detected capacity value is too small, then the capacity fault will displayed.
There may be the following reasons:
Do not do a calibration for a long time or the humidity and temperature has changed a
lot. Do a calibration again to clear this fault.
Part of the sensor has been replaced and installed again. Do a calibration again to clear
this fault.
There are bad connections of the wire. Check the wire connections。
Work piece do not have a good conduction with the shield of the amplifier. Check the
wire to the earth and the wire on the amplifier shield.
Parts of the laser spot are located on the capacity sensor and cause the temperature
rising. Please check the optical path and the optical devices.
1.1.25Crash alarm
When the laser head has touched the metal work piece for a certain time, the crash alarm will
be displayed on the displayer. If the laser head do not touch the metal sheet, there is still crash
alarm displayed. There may be the following reasons:
There is a short between the nozzle and the shield of the amplifier.
The axial cable between the amplifier and the capacity sensor is damaged or the
amplifier does not work.
