Posted 14 Jul 2022 Hello Experts We have a machine with Mitsubishi Servo MR-JE-2008 With PLC Fx 5U & HMI GS2107 Yesterday we altered PLC by adding a row with input and timer & used this Input in next rung for weld start Although we did not find any linkage but found "'Screen error Ok"' on HMI and after pressing Ok, HMI screen getting blank. We restored original PLC backup - PLC in Run Mode still ""Screen error Ok"" on HMI Via GT designer 3, we have loaded HMI backup, now HMI screen is OK and normal Getting Ab on Mitsubishi drive - we feel it is not an error but due to this we are unable to rotate motor although other functions like door open/close etc Ok In PLC, online mode, we are finding Servo in ON but unable to understand Ab on Drive and may be due to this, unable to rotate motor Please refer to attached HMI, PLC & Servo Backup Request advice HMI BACK UP.GTX PLC BACKUP.gx3 Flange Welding_Tag Line Servo Backup.mrc2 Share this post Link to post Share on other sites
Posted 18 Jul 2022 Hello Experts We could fix the issue by reloading Servo backup - mistake was during read to PLC, servo backup was not taken earlier Thanks for your attention To ensure servo backup is also taken, during read from PLC, we need to select all, also we need to click on checkbox with Servo, kindly confirm Share this post Link to post Share on other sites
