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. F1 type, 2 variables.įind the variable $PARAM_GROUP. 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?ĭisregard my original post!! The fact that this robot is wall mounted is significant. My new to me Fanuc Lr mate keeps saying it needs to be calibrated. What would be the issues to test for? Is there a software-defined maximum current to servo value we could check, perhaps? 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. (33) SRVO-046 SVAL2 OVC alarm (Group: i Axis: j) o (Explanation) This alarm is issued to prevent the motor from thermal damage that might occur when the root meant square current.

Download Emulator Android Untuk Pc Ram 1gb. 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.
