1. Start the robotic arm and cannot start normally.

2. Troubleshooting of robotic arm cable plugging. Re-plugging all the cables of the robotic arm and starting the robotic arm correctly from the beginning, the problem still exists. And the preliminary point is that the I/O line is shorted incorrectly.

3. Robotic arm I/O line shorting test. Under normal circumstances, the external emergency stop I/O line needs to be shorted. Because there are two sets of I/O lines that are not shorted, the problem is not solved by selecting the permutation and combination method for shorting, and the mechanical arm is started normally and the MOTOR is pressed

Fourth, the engineer sought technical support, and after contacting the technical engineer by phone, he proposed that the mechanical arm was burned out. Disassemble the upper cover of the robotic arm controller, unplug the fuse, and use the multimeter resistance level to check. It was found that except for the first fuse, the other fuses were normal.

5. Confirm that the blown out fuse is the reason why the robotic arm cannot work normally.

Misunderstanding of industrial robots - Denso robots Misunderstanding of industrial robots - Denso robots

Myth 1: Only recognize the brand, brand first. The correct concept is that when buying a robot, the brand can be used as a reference, but it can't be too sure. It is mainly considered by looking at the composition of the central elements, the degree of design optimization with its own use, and the degree of consistency between the intention and function of use. ...

How to select the diameter of the welding wire of the DENSO robot How to select the diameter of the welding wire of the DENSO robot

The main consideration in selecting the diameter of the wire is the thickness of the material to be welded. If the wire is selected that is too small for the data, the welding process is underpowered, and time and production costs are wasted, as the welder has to spend more time completing the weld. Because the weld may not be fully permeable ...
