Does anyone have experience troubleshooting a SC1 not synchronized fault after a Serial Measurement board was replaced & updating the rev counters.
Thank You,

Update the serial measurement data from the robot to the controller.
-
Then you are going to need to redo your safety controller configuration, and synchronize the robot and safety controller. Probably you have a routine to make the robot move to a switch.
-
Actually, after reading in the robot memory to the new SMB, the numbers will match, so maybe just do the sync routine.

Lemster68,
Where is this in the teach pendant menu if you don't mind me asking.
This is the only ABB we have in production in the foundry & the rest of the robots are KUKA & Fanuc.
There is a priority order that has to be finished ASAP.
Thank You!

Control panel, calibration, calibration offsets,, more or less. What version of robotware? Probably older judging by the date of manufacture.

Just to share what i had to do to get the SC1 synchronization fault to go away:
ABB Robot IRB6640 Serial: 6640-50428 Foundry Plus
Set the PC that will be connecting to the robot controller with DHCP Enabled.
Connect the ethernet cable to the X2 port on the main Computer in the Robot Cabinet.
Using Robot Studio 2020 version, select Controller 1 click connect, go under the safe move menu.
Login with the user & required password.
Found the Servo Motors were not synchronized- Clicked on Synchronize motors.
Had to Reboot the robot controller with the Teach Pendant Warm start option.
Update the Rev Counters, Ran the Maintenance routine at 25% speed, ran the safety synch position routine, and last but not least the Software synch routine.
Software synch was successful.
Put the Robot back in production.

Thank you Srtautomation for sharing.
I am have the same issue with the robot ABB Robot IRB6640 M2004 which stuck on "SC1 not synchronized" fault.
* About "Found the Servo Motors were not synchronized- Clicked on Synchronize motors." posted above, can you share more details? where can find motors that are not synchronized.
* Tried to synchronize with Robostudio 2020 under safemove menu , read joints values from controller, joint 1,4,5,and 6 are 0.0, joint 2 =-0.6, joint 3=-0.5. it was not able to move the robot before clean the fault, I set these values to synchronize and write to controller. it was not work. will try all 0 tomorrow.

issue fixed.
Dual change signal, made x10.5 and x10.6 on/off at the same time. got synchronized.
not synchronized reason for my case is that I get 10.5 to (GND) and then turn on/off 10.6 to +24V, not at the same time.
