I'm a student and recently I ran into the SRVO-038 error using R-30iA with my school robot. I used this procedure https://2rirobotics.com/blog/u…038-servo-pulse-mismatch/ but the robot failed to calibrate.
After that I followed post #11 here Mastering by Direct Entry of Encoder Pulses and failed to calibrate again.
I then entered back the old $MASTER_COUN values , but the picture I took from them was not that good because small part of the picture was behind a lamp glare and I'm not sure I entered the correct value for axis-6. After that I did the quick master and zero point master (robot is in 0-position).
Now I get the SRVO-138 alarm, and the value for axis-6 in $MASTER_COUN is way off. SRVO-138 tells me the pulse coder for axis-6 is faulty.
So is there a problem with the pulse coder or did I mess up something? There is no backup available. Is there a way to fix this? Any help would be much appreciated.
