The system can
only machine
straight line and
fail to machine a
circle.
Initialize the system if any
parametric problem
Initialize the system parameters.
Replace the machining
program and test run again.
If no more problem, check that
machining program.
Check the program or return it to the
manufacturer for diagnosis.

ignition is going
on.
a. The power supply unit for plasma, CNC system and the enclosure of machine must share a ground wire
that is 2mm thick at least in diameter and well connected to the ground.
b. Shielded cables must be used for the system input/output and the exposed part at the cable end must
not be longer than 30mm.
c. The unused input end must be connected to 24V ground wire.
d. A 0.01uF capacitor should be used between the 24V ground wire and enclosure(shielded cable).
e. Use an isolation transformer(380V-220V) and as interference suppressor if it is possible.
f. Separate the operational power supply for high-power welding machine/cutting machine from that for
CNC system.

After replacing batteries, press G, G and 3 in
the system main window successively to
format the program area.
No system output
Check if 24V power supply is
normal or not.
Measure the voltage between
Pin 24 and Pin 25.
Check and replace the switching power
supply unit.
Check if the four relays on the
rear panel are reliably
connected, if the relay
operation is normal and if the
contact is functional.
Replug or replace the relays.
