Turn On Power

Also checkout the new CB3 forum

Press the ON button on the UR monitor.

turn_on_1

A messages appears that say “No Cable” –

Which normal and no actions are necessary for this.

turn_on_2

During boot you will see various screens loading and checks – this is normal and it takes 1 – 2 minutes to boot. You will also hear the fans turn in the controller box.
 After booting the monitor will show one of these two screens depending on if the Emergency push button has been pressed.

turn_on_3

turn_on_4

If the emergency messages are shown – then turn the red mushroom button clockwise. 

Then press the “OK” on the screen.

turn_on_5

It is also possible to use the mouse and click on the OK or “To Initialization Screen”.

From this stage on and the rest of the manual a mouse click is used instead of pressing the touch screen monitor if not mentioned otherwise. (The mouse click or press with finger has the same result).

This will take you to the “Initialization” screen because at this point just after a cold reboot the robot does not know where the joints are situated. This also apply if the robot has been used and programmed before – after a cold reboot this initialization is necessary for the robot to find the position of the joints.

Notice that the screen say “Power OFF” and all six lamps for the joints are yellow. The controller has power ON of cause, but the robot is still Power OFF.

turn_on_6

Press the “ON” button to turn on the power to the robot.

The status will go to “READY” for each joint, but the lamps are still yellow because the position of the joints is still unknown to the robot controller.

turn_on_7

Press the “Start” button. You will hear six clicks – click – click – click – click – click which are the mechanical breaks inside the joints that are releasing. The mechanical breaks are use in transportation and after an Emergency stop to ensure the robot joints do not move.

turn_on_8

After a short time you will see the “BREAKE RELEASE” go to “INITALIZING” status for all joints. In some firmware version you will also shortly see the messages “BOOTING” for the joints

turn_on_9

The robot does still not know the position of the joints and we have to help the robot on the way in order not to crash into something (including into itself) when the robot starts moving.

Because we have just unpacked and the robot is folded together in a tight position we will use a very controlled method this first time. Later we will see how a shortcut can be made when the robot is cold started for a position where the robot is fairly free and unfolded.

turn_on_10

In this position we need to make sure the robot is moving “upwards” so it is not crashing into itself. If it crashes into itself it will stop with a safety stop, but the robot could be slightly scratched and we want to avoid that especially when it is new.

The robot is a 6 axis robot which means it has six joints and six axis freedom of movement. The joints are named 0, 1, 2, 3, 4 and five counting from the base – or with names it is Base – Shoulder – Elbow – Wrist 1 – Wrist 2 – Wrist 3.

So in this case we want the elbow joint to move upwards to make the robot freer. So press and keep pressing the arrow pointing right – look at the photo at the right where to mouse pointer is placed.

turn_on_11

Keep pressing and you will see the robot rise upwards.

turn_on_112jpg

After a few seconds the “Elbow” joint will report “OK” on the monitor. This means the robot now knows where this joint is positioned. It is not necessary to turn one full circle. What you see on the photo is normal.

turn_on_13

Now we want the “Shoulder” joint to move upwards in order to get the more upright and if turning down we might crash into the table if the robot sits on a table.

Press the arrow pointing to the left for the “Shoulder” joint.

turn_on_14

You will see the robot move further upwards by the “Shoulder” joint movements.

turn_on_15

After a few seconds the “Shoulder” joint will also report “OK” and the position of the joint is now know to the robot controller.

turn_on_16

Now the robot is already quite good up and free so for the last 4 joints we will use a faster method. Press the “Auto” button on top of all joints where it says “Robot”.

turn_on_17

Keep pressing the “Auto” button. Now notice how the remaining 4 joints all move until all of them say “OK” which means the robot has been Initialized and all joint position are know to the controller.

This “Auto” method is actually possible for all 6, but since the robot was folded we choose this controlled method until the robot had more space. We will try that very soon the second time we start up the robot.

turn_on_18

All the joints on the monitor reports “OK” and notice how all the lamps turned green. The robot is now initialized and ready to be programmed or load a program if we already have made a program before.

turn_on_19

Press the “OK” button at the bottom of the screen which takes you to a Main Menu screen.

turn_on_20

Try and press the “About” button. A screen with software version information appears and if an IP address has been assigned it is also shown in this screen. We will learn later how to set an IP address so this is properly blank on your screen.

turn_on_21

Press “OK” and you will return to the “Main” menu.

For training purpose the shortcut method for initializing the robot will be explained now because the robot is already up and free. So shut down the robot by pressing the “SHUT DOWN Robot” button.

turn_on_22

Confirm the Shutdown by pressing “Yes” button.

After a few seconds the robot and controller are turned off.

 

Notice how the six clicks could be heard because the mechanical breaks engaged to make sure the robot does not fall uncontrolled down to the floor.

 

Turn on the robot for the second time.

turn_on_23

Turn on the robot again following the same procedure as explained above until you reach the “INITALIZING” screen.

turn_on_24

Since the robot is up and free then press the “Auto” button on the top where it says “Robot”.

Press only briefly (0.5 – 1 second) and notice which direction the robot moves. Press again only briefly (0.5 – 1 second) and notice again which direction the robot moves. This is useful if the robot was power off near some obstacle or inside a machine – then we can control the movement direction during initializing because alternate press will cause the robot to go in opposite direction.

turn_on_25

When you know the direction of movement you wish the robot to go during the initializing procedure then keep pressing until all joints report “OK”.

turn_on_26

This time the initializing procedure went much faster and this will often be the choice of method during a cold reboot of the robot.

Press the “OK” button at the bottom of the screen to go to Main menu.

    Hi.

    I am having an issue.
    I am using an UR5 that worked completely fine for several weeks prior to today.

    There was a power outage when turning on the control box.

    After this the TP wont even start, note: it never got as far as to start as the power went out maybe 1 second after turning it on when the outage happened.
    Now, when i press power on the TP, the no cable message pops up, but instead of booting the TP simply turns off.
    All cables from the TP to the control box appear to be correctly plugged in.

    Do you know what is wrong? Is it possible to fix without sending the robot to service?

    Thanks

      Hi Magnus

      Thanks for the question.

      It is hard to say what is wrong so you might need to send it to service.

      Hi Rahul

      Thanks for the question.

      I have not seen any informations for the system configuration and I am not aware of if it is possible to install such software as you mention.

    Hello Lars,

    We have a problem with Power ON the robot. The robot is not getting ON suddenly. The controlbox status at the Initialize Robot screen shows as “Failure”. So that I couldn’t power ON the robot. I didn’t find any troubleshooting procedure for that. How to fix this? Please help us. If you send us little more detail, it will be helpful.

    Thanks!
