We just bought a used Fanuc M16 with R30ia controller. I finally managed to solve all error code that I had except that the robot won't move. The only alarm message that I got is when I try to move it's say that it's not calibrated.
I have try several time mastering et calibrating procedure that I found in the manual but each time, at the end it's says not mastered or not calibrated. It seem that i'm stuck in a position that I need to move the robot enough to pulse coder to succeed mastering and calibrating but I need to master et calibrate to be able to move. Did I miss something? How do I get out of this loop problem. I tought that if I could disengage brake et turn axis manually it will probably get me out of this situation.
I can't remember their name right now but I will post it later. But it didn't work. Brake was still on. Couldn't move at all. Note that the battery in the robot was missing when we received the robot. If keyswitch is in manual and pendant is on, you should be able to drive the robot.
Remedy: Reset the alarm, and jog the axis on which the alarm has occurred until the same alarm does not occur again. Jog one motor revolution. This alarm must be cleared before mastering. Select a method for calibrating the robot. If the robot can not be calibrated, mastering is required.
But it doesn't work. And i can't jog any motor so i can't reset SRVO Which prevent me from mastering. It's a circle from hell. And i disable everything that i saw in the profibus menus. Is it possible that their something that i forget to disable or unassign and prevent the robot from moving. OK looking at the error list there is nothing that you posted that will stop you from jogging the robot listed.
In an un-mastered state, the only was you can jog the robot is in joint mode. If you still can't jog the robot go back to the alarm menu and check the alarms listed, if there is something different post it here.Robot calibration is a process used to improve the accuracy of robots, particularly industrial robots which are highly repeatable but not accurate.
Robot calibration is the process of identifying certain parameters in the kinematic structure of an industrial robot, such as the relative position of robot links. Depending on the type of errors modeled, the calibration can be classified in three different ways.
Level-1 calibration only models differences between actual and reported joint displacement values, also known as mastering. Level-2 calibration, also known as kinematic calibration, concerns the entire geometric robot calibration which includes angle offsets and joint lengths.
Level-3 calibration, also called a non-kinematic calibration, models errors other than geometric defaults such as stiffness, joint compliance, and friction. Often Level-1 and Level-2 calibration are sufficient for most practical needs. Parametric robot calibration is the process of determining the actual values of kinematic and dynamic parameters of an industrial robot IR.
Kinematic parameters describe the relative position and orientation of links and joints in the robot while the dynamic parameters describe arm and joint masses and internal friction. Non-parametric robot calibration circumvents the parameter identification.
Used with serial robots, it is based on the direct compensation of mapped errors in the workspace. Used with parallel robots, non-parametric calibration can be performed by the transformation of the configuration space.
Robot calibration can remarkably improve the accuracy of robots programmed offline. A calibrated robot has a higher absolute as well as relative positioning accuracy compared to an uncalibrated one; i.
Absolute positioning accuracy is particularly relevant in connection with robot exchangeability and off-line programming of precision applications. Besides the calibration of the robot, the calibration of its tools and the workpieces it works with the so-called cell calibration can minimize occurring inaccuracies and improve process security. The international standard ISO  sets different performance criteria for industrial robots and suggests test procedures in order to obtain appropriate parameter values.
The most important criteria, and also the most commonly used, are pose accuracy AP and pose repeatability RP. Repeatability is particularly important when the robot is moved towards the command positions manually "Teach-In". If the robot program is generated by a 3D simulation off-line programmingabsolute accuracy is vital, too.
Both are generally influenced negatively by kinematic factors. Here especially the joint offsets and deviations in lengths and angles between the individual robot links take effect. There exist different possibilities for pose measurement with industrial robots, e.
The robot errors gathered by pose measurements can be minimized by numerical optimization. For kinematic calibration, a complete kinematical model of the geometric structure must be developed, whose parameters can then be calculated by mathematical optimization. The common system behaviour can be described with the vector model function as well as input and output vectors see figure.
The variables k, l, m, n and their derivates describe the dimensions of the single vector spaces. Minimization of the residual error r for identification of the optimal parameter vector p follows from the difference between both output vectors using the Euclidean norm.
For solving the kinematical optimization problems least-squares descent methods are convenient, e. This procedure supplies corrected kinematical parameters for the measured machine, which then, for example, can be used to update the system variables in the controller to adapt the used robot model to the real kinematics.
The positioning accuracy of industrial robots varies by manufacturer, age, and robot type. Using kinematic calibration, these errors can be reduced to less than a millimeter in most cases.
An example of this is shown in the figure to the right. Accuracy of 6-axis industrial robots can improved by a factor of In the industry, there is a general trend towards substitution of machine tools and special machines by industrial robots for certain manufacturing tasks whose accuracy demands can be fulfilled by calibrated robots.
Through simulation and off-line programming, it is possible to easily accomplish complex programming tasks, such as robot machining.I am guessing this is how you calibrate as this procedure is in the Calibration Manual of Fanuc and I couldn't find any other details on calibrating the robots.
I am new with Fanuc Robots, would appreciate any help, I am not sure how else to calibrate? The robot needs to be mastered and then calibrated before you can run the vision master recovery. You need to manually jog the robot to line up all of the "witness marks". You should then be able to run the program. I tried the same, on selecting zero position master it gave me a message "gravity compensation is enabled confirm you have set payload data correctly; execute mastering?
We would not need gravity compensation on our system as our parts are less than 10 pounds. Just to see if this will work I selected yes and calibrated. Do I need to disable gravity compensation? The arms are not bunched up at all so I am not sure why it is giving this error. Appreciate your time. I would disable the gravity compensation as it will alter the mastering. But I don't think that having it enabled is causing this. After you master and calibrate it what are your joint positions, they should be all zero.
I am going to assume they are. It is possible that the robot is trying to go to the first position in the program from the zero position and that the robot maybe trying to move axis 1 "through" the axis limits. Abort the program, jog the robot near the camera and try to execute the program from that position. Thank you for all your help. After I mastered and calibrated it, all the joint positions were zero. All the joints are within the limits and as you suggested I tried different positions, but I am still getting the same errors MOTN and MOTN while trying to record new reference position.
By jogging the calibration grid near the robot, you mean how close? As I tried different positions by keeping it between mm to mm range from the camera, but no luck. I am attaching the joint axis position to show that they are not bunched up at all.
Do you have any other suggestions that I can try? Attached are the pictures for reference. I figured it out, my mastering was not accurate, that is what was causing the issue of singularity. I appreciate your help Mike!Using the Teach Pendant, you can develop programs that are stored in the teach pendant, and then, more easily and quickly ran when needed.
