Operation Flow
Troubleshooting
Fault
Trouble shooting
The screen don’t display
when power on.
■The terminal of power supply wiring is error.
Follow the nameplate to rewire.
■The source voltage is too low.
■The connector is not connected well.
The back gauge motor
doesn’t run when X-axis
is operated, but the
slider motor runs.
The wires of these two motor are in reverse,
please rewire.
The motor doesn’t run
when operating.
■Check whether the machine is impeded, or
whether the slider is back to TDC
■Check whether the motor wire is connected
well.
The motor can’t mutually
convert from high to low
■Check whether the signal is in effect, or
whether frequency converter is normal.
■Check whether parameter Mute Dis. is
programmed correctly.
The step can’t be
changed in Multi-Step
mode.
Check the START terminal is connected to
+24V when the slider is on TDC.
The counter doesn’t
work in Multi-Step mode.
Check the START terminal is connected to
+24V when the slider is on TDC.
Lose control of the
system
■Check whether the encoder cable is
connected well.
■Check whether the motor direction wiring
(X+, X-, Y+, Y-) is correct.
The actual position of
X-axis or Y-axis is
unchanged or unshown.
Check whether the encoder cable is
connected well or correctly.
Notice
When the RED indicator light is on, you can program the parameters.
Only when the page is on SINGLE, Total Parameters page or the Step 1
page, you can press Startup Key to run the device.
Press Stop Key to stop the machine, and the device backs to the previous
page.
When the page displays the alarm info, you should resolve the problem
with some effective measures (see Alarm List). The device will be reset
by the self-diagnosis function.
