b. Ensure that the capacitance change during blowing is less than 50.
4. If the alarm is still reported, increase the servo drive gain as needed.
4.4.12 System Reports Material Collision Alarm when the System Has No Movement
Reason
The current capacitance is equal to or smaller than the Touch Part Capacitance value.
Solution
Follow the steps below to help troubleshoot:
1. Ensure that the machine and material colliding capacitance are correct.
If not, replace the machine and material colliding capacitors.
The normal machine capacitance for SE001 later than V1.4 is about 650,000 while
that for SE001 earlier than V1.4 is about 1.3 million.
2. Use a multimeter to measure the conductivity of the copper core between the cutter
nozzle and sensor.
If the conductivity is zero, the cutter is damaged.
3. Use a multimeter to measure the conductivity of the copper core between the cutter
nozzle and RF cable.
If the conductivity is zero, the RF cable is damaged.
4. Check to see if the resistance between the No.1 and No.2 ports of SE001 is 4.8
KΩ–5.3 KΩ (tolerance≤5%) and if the resistance between the No.2 and No.4 ports
is 0 Ω–1 Ω.
If not, SE001 is damaged. Replace it.
5. Measure the conductivity of the corresponding pins of the M16 three-core aviation
cable.
If the conductivity is zero, replace the cable.
6. If the alarm is still reported, replace the EX33A extension terminal board.
4.4.13 Follow Overshoot
Reason
The speed of servo drive response is slower than the command speed.
Solution
Follow the steps below to help troubleshoot:
1. Ensure that Pulse Equivalent, Speed Gain, Pulse Counter Per Turn are set
correctly.
2. Increase the servo drive gain.
3. Ensure matching between the Z axis maximum speed and dry run speed. The Z
axis dry run speed can be lowered by certain amount if needed.
