Couldn't figure out why and once we deleted this second motion group everything went back to normal. We suspected something of this sort earlier on and tried to add a new motion group defining the mount to be at 90deg through a controlled start but once the motion group was created and a cold start initiated we got a SRV-021 (Servo SRDY off error) on all axis in the new group (GRP2). There is a setting to change the wait time for the brakes to come on. Then cycle the power off and then back on for the change to take effect. It is under the setup menu Menu, 6, F1 type, general. Check to make sure you have 'brake on hold' enabled. Cycle power and retest for the OVC alarm. This will not correct the world frame but it will allow the robot to see gravity properly. Find the variable Mount angle and change the value to 90. There may be more than one param goup, make sure you select Group 1. Go to system variables menu, 0, 6.ДЇ1 type, 2 variables. The loading on J1 at 30 degrees above parallel is what is causing your OVC. Current drawn over some time causes an error)? Any other ways to solve this issue? Disregard my original post!! The fact that this robot is wall mounted is significant. If that is not available, is there a way to enable brake on J1 mid-program, to ease the current load (my understanding is that the OVC error is cumulative, i.e. What would be the issues to test for? Is there a software-defined maximum current to servo value we could check, perhaps? Robots were functioning fine (a couple of years ago) in normal orientation, and I did jog them around after mounting on the wall - no errors.

We've checked the mains voltage - it's 472VAC, robots are wired for 480. The problem hasn't appeared during testing, only when we went to programming and robot was held by servos for extended periods of time we started to get SRVO 46 OVC alarm on angles of J1 between parallel to the ground and about 30 degrees. We have a wall mounted Fanuc Arcmate 100iB, RJ2 controller. I thought I'd clarify a bit the aspects of this problem. Hi everyone, We work together with latendal on this project.

I've considered restricting motion on the J1 axis by defining a motion group that excludes it because it is the author of the OVC alarm in the hopes the brakes would be applied to the j1 axis and prevent this motor from drawing more current but even this is proving very challenging as i do not have the software installation manual I am literally out of ideas on what to do next! Nuova Elettronica Handbook For Employers there. I've checked the phase to phase voltage at the servo amplifier and its well over 170VAC, also checked the brake connector and it seems to be fine. I am trying to setup a program on my controller for production, however when i put the robot in certain positions(orientations) i get an OVC alarm. Need CNC Machine Parts?
