When does the error occur?
Did you check the brakes?
Try to change acceleration and deceleration. Increase the acceleration and deceleration times (C1-01 through C1-08).

Dear Jadam,
It happened mostly when Normal mode down direction, INS mode UP and Down was fine.
I have increased C1-01 to C1-08, but no effect (1.5-->3.0), I called the repair team also to check the brake, guide shoes, etc.
When OL1 happened, the monitor showed 59A and the motor rate current was only 21A.
