Error 4028 · CNC 8055 M · CNC 8055 T
Message: The light does not reach the CNC through the optic fiber
Detection
On power-up.
Effect
It stops the movement of the axes and the spindle, eliminating all the enable signals and canceling all the analog outputs of the CNC. When detected from the position loop, it opens the position loop and sets the LOPEN mark to ·1·.
If it is in execution, it interrupts the execution of the part program of the CNC of all channels.
Besides this, it activates the external emergency output.
Cause
The signal sent by the CNC through the optical fiber does not return to the CNC.
Solution
Check the condition and installation of the fiber optic cables. Check that the light going "OUT" of the CNC is going through the drives and comes "IN"to the CNC.
If the cables are OK, remove the drives from the ring until the error no longer comes up.
