Reset -X- failed
Every movement (X,Y, R and C) has a maximum time (about 20 s)
to reach the reset position after pressing the RESET pushbutton
on the control panel.
If the X movement does not reach its reset position in time, the
alarm is generated.
Possible causes:
1.
X movement step motor defective
2.
belt of the X movement step motor damaged or belt tension
incorrect
3.
X movement blocked
4.
X movement step motor +42V power supply is not correct
on the PC1 system control board: this power supply comes
from the PFC board PN1.
Check the power supply value on test points TP1 and TP7
(GND) on the PFC board PN1; by checking the LED H3
(ON=OK, OFF=NOT OK) on the system control board PC1;
by checking the LED V5 (ON=OK, OFF=NOT OK) on the PFC
board PN1.
Check whether fuse F2 on the PFC board PN1 has blown.
PFC board PN1 defective.
System control board PC1 defective.
5.
wiring damaged between PC1 system control board and X
movement step motor (see principle diagram Z1-10)
6.
X movement reset position optoswitch S15 damaged
