Hi everybody!
We have a robot ABB IRB 1500 M92 with S3 controller. The system includes CPU board DSQC230, safety board DSQC252, I/O board DSQC223 and DSQC224 etc. All of the power supply voltage is within normal limits. There is the following problem. After Power ON, the system starts the diagnostic test. Pendant's lcd shows "ABB ROBOT SYSTEM SELF TEST". The red led`s “F” is light on all these units.
Then:
1) The green led “DC” from DSQC252 is on (red led “F” - off).
2) The green led “EN” from DSQC230 is on (red led “F” - off).
2) The green led “EN”, “EM”, “LIM” from DSQC252 is on.
Pendant's lcd shows "ABB ROBOT SYSTEM SELF TEST".
On the boards I/O DSQC223 and DSQC224 still burning red leds “F”.
After some time the pendant's lcd shows the fault message "PROG UNIT COMMUNICATION ERROR".
Pls help me I am in an emergency situation.
