Troubleshooting
Fault
Trouble shooting
The screen don’t display
when power on.
■The terminal ofpower supply wiring is error.
Follow the nameplate to rewire.
■The source voltage is too low.
■The connec tor is not connected well.
The back gauge motor
doesn’t run when X-axis
is operated, butthe
slider motor runs.
The wires of these two motor are in reverse,
please rewire.
The motor doesn’t run
when operating .
■Check whet her the machine is impede d, or
whether the slider is back to TDC
■Check whet her the motor wire is connected
well.
The motor can’t mutually
convert from high to low
■Check whet her the signal is in effect, or
whether f requency c onverter is normal.
■Check whet her 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 ofthe
system
■Check whet her the encoder cable is
connected w ell.
■Check whet her 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
W hen the REDindicat or light is on, you can program the parameters.
Only when the page is onS INGLE, Total Parameters page or the Step 1
page, you can press Startu p Key to run the device.
Press StopKey to stop themachine, and the device backsto theprevious
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.

Diagnosis
<NOTE> The following is only described how todiagnos e the encoder, and
for the othersdiagn osis, just according to the page tips to operate.
1. Press P key several times, switching to the CONST page.
2. Press Numeric Keys to input the password 5656, and press Enter Key to enter the DIAGNOS E page.
3. Select 5. Enc. DIAG. or press Numeric Key 5 directly, and then press Enter Key to enter the ENC. DIAG. page.
4. Rotate the encoders of X-axis and Y-axis, the page displays the pulse changing. The corresponding C-pulse will jumpbetw een 0 and 1, whichind icates the encoder port is normal.
