X travel back protective fault Commutator turning machine ND-LHL-QSF
Question:
Our Nide turning machine is showing the error message as shown in the below screen shots and not able to reset the error
System screen does not respond to change the below shown value ( highlighted by a circle in the picture ) and the machine is not coming to home position
Kindly help to resolve this issue
Solution:
Based on the photo information, we found below problem,
1. The rotor No is 50, in normal condition, we set the rotor no as 1, 2, 3, 4 --- 30 in order if there are 30 kinds of armatures,
We suggest use the no below 30 and set them in sequence, if the rotor no skip, jump to a big one over 30, there might be data disturb in PLC place
2. The X,Z data is very big and X travel back protective
Please follow below step to solve,
1) There is a sensor switch on X axis plate front or back side, under the cover, there is a U shape,
Please use a metal thing to touch the U sensor, loose, touch, loose, repeat,
then the other people observe the 04 indicator on the PLC, indicator should blinking,
if always OFF or always ON, the U sensor is broken, you need to change one,
2) If U sensor is good, please go to check the 03 indicator,
Turn to the cutter setting screen, for the X axis there are four direction, front, back, left,right, please let the X axis go to front very slowly,
and check if the 03 turn to On
3) If 04 indicator ON, 03 indicator ON, the machine have no problem
4) The cutter move to front (X travel back protection, X axis could only go to front), close to the surface of commutator, then do the ''Cutter setting' process,
to update initial position,
