Mitsubishi Servo MR-JE-2008 With PLC Fx 5U HMI GS2107

2 posts in this topic

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

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
