1. Base check of the servo motor of the KUKA robot
Since the robot servo motor is included in the library card high-resolution detector, in the event of a collision, the impact can cause a problem with the servo motor that the robot library card should provide for a repair check:
(1) Have you suffered any mechanical damage?
(2) Is the rotating part normal by hand?
(3) With the brake motor, is the brake normal?
(4) Are the screws or gaps loose?
(5) Are they installed in wet, volatile and dusty places? Wait a minute.
2. After the repair of the servo motor of the KUKA welding robot is completed, the device of the servo motor should pay attention to the following points:
(1) Since the waterproof structure of the servo motor KUKA is not very tight, assuming that the cutting fluid enters the lubricant, the insulation performance or winding short circuit can be caused, therefore, it should be noted that the motor avoids splashing as cutting fluid.
(2) When the KUKA robot servo motor is installed on the gearbox, the lubricating oil surface of the gearbox must be lower than the servo output shaft to avoid the lubricating oil entering the motor.
(3) Fixing library servo motors, gears, timing belt couplings and the like, in any case, the force acting on the motor of the motor shall not exceed the allowable radial connection, axial load
(4) The positive brick connection between the servo motor and the control loop should be performed according to the manual. Faulty connections may cause the Kuka robot servo motor to go out of control or oscillate, or damage the motor or mechanical components. After the wiring is completed, the insulation between the power cord and the motor housing must be measured before the power is turned on.
3. KUKA robot servo motor encoder replacement: Assuming that the KUKA robot servo motor encoder is bad, the pulse encoder should be replaced.
Common symptoms of the repair of servo motors (servo motors) for KUKA robots are:
1。 KUKA robot servo motor power, mechanical oscillation (plus/minus)
2。 The servo motor of the KUKA robot is powered on, and the mechanical action is abnormally fast (flying car)
3. The orientation of the spindle of the KUKA robot cannot be moved or the directional movement is not in place
4. Present NC error alarm
5. KUKA robot servo motor servo system alarm
6。 KUKA robot servo motor encoder alarm
7. KUKA robot servo motor stuck, etc.;

KUKA robot loads are processed during zero point correction
When calibrating at zero point, it is not necessary or advisable to disassemble the load things; Otherwise, the TCP may have to be recalibrated after disassembling and assembling things.
In practice, it is possible to carry out the zero-point proofreading operation after the installation of the robot is completed. However, in the future, when you re-calibrate the zero point or check the zero point, you will ...
