Step 1: View the environment

1. Recognize the ambient temperature: the ambient temperature of the KUKA control cabinet is required to be between 5°C-45°C, the operating environment temperature of the robot body is 10°C-55°C, and the operating temperature of some new models is 0°C-55°C (see the robot skills manual or KUKA official website for details). If the ambient temperature is too low, the robot will be turned on abnormally, and it is necessary to improve the ambient temperature or preheat before putting it into use.

2. Admit the on-site environment: admit that there are no debris on the site, no obstacles or obstructions that affect the normal production of the robot, no damage to the safety fence and safety passage, and normal positioning of the line workpiece.

Step 2: Electrical inspection

1. Line viewing: Admit that the power cord of the robot control cabinet is normal, the power cable between the control cabinet and the robot is normal, the grounding is normal, and the other cables are normal.

2. Equipment inspection: Acknowledge whether the electrical components of the robot control cabinet are normal, and check whether there is any appearance damage or incineration. It is also necessary to pay attention to the peripheral electrical components, such as PLCs, operating switches, sensors, etc.

Step 3: Mechanical viewing

1. Check the appearance of the robot: admit that the cable connectors, fixing cards, etc. are not loose.

2. Observe the robot body: admit whether there is lubricating oil leakage in each joint.

3. For robots with a balance cylinder (CBS), first check the balance cylinder for traces of oil leakage. Once the robot is powered on, turn the A2 axis to a -90° vertical position and check if the balance cylinder pressure is within the normal range.

4. Check the zero point of the robot calibration: First of all, before viewing, all axes are run to the zero point to pre-calibrate the alignment.

Then, look at the zero point with EMD –

Here it is important to note that there are two methods for the robot to calibrate the zero point: (1) the normative method and (2) the load calibration method

> Using the "Specification" method, it is important to note that the current load of the robot is the same as the previous zero point check.

> Using the "Proofing with Load" method, the requirement goes to the "Biased" menu to see the zero point.
