Good day everyone, I am working on a problem on a Mitsubishi Q series PLC and motion system. The system consist of a Q12H PLC CPU and 2 x Q173CPUN Motion CPUs. The first motion controller controls 23 x MR-2JS-_B Servodrive and thesecont motion controller CPU controls 6 x MR-2JS-_B Servodrives. They are all using SSCNET1 system.The machine have been working fine all along until the machine stoped for 3 months because we were waiting for one spare part that was coming from oversees during covid lockdowns. When we restarted the machine, the servodrives could not home. When we were busy checking for the problem and before finding the problem, the machine just started homing. This keeps on happening over and over. Everytime you stop the machine overnight, it just stop working then when you are busy troubleshooting, it just come to like. In the time when it is not responding, we figured out that when we jog the servodrive controlled by second Motion controller CPU for the HMI, the drives jog fine but the servodrives controlled by first motion controller CPU does not respond. I have tried jogging the servodrives indipendently using Setup161E and they move . I even changed the motion CPU but to no success. When you monitor using MT Developer 2, the are no errors. Is there anyone who might have an idea on what might be the probable cause
Frans@TCPM posted a topic in MitsubishiHi, I have a challenge with GX developer version 8.63R (SW8D5C-GPPW-E). I'm trying to verify 2 projects (offline). Some programs I know there are changes but they are not shown in the verification. In 1 program I did see the last checked change was in step 1496 (next change I did see by manual check was step 1502. it seems like this type of verification is limited to 1500 steps to check. Is there any way I can make this offline verification work? the most progams that we have in our project are over 2000 steps. big thanks in foreward
