1. Appearance inspection
Check the cables and wiring: Check whether the cables are aged, damaged, scratched or dirty, and whether the terminals and plugs are loose or in poor contact.
Check the control cabinet: Clean the dust and debris in the control cabinet, check whether the internal components are intact, and whether the markings are clear.
Check the motor and drive components: Check whether the motor appearance has abnormal wear or damage, and whether the drive components are firmly installed.
2. Electrical performance test
Check the power supply voltage: Confirm whether the system power supply voltage meets the equipment requirements and whether there is a circuit break or leakage.
Use a multimeter to detect: Check whether the voltage, current and resistance in the electrical system are normal. Check whether the wiring is correct and whether there is a short circuit or a circuit break.
Check the insulation performance: Use a megohmmeter to test the insulation resistance between electrical components to ensure that the insulation performance is good.
3. Control system inspection
Check the control program: After importing the control program, check whether the program logic is correct and whether the motion parameters of each axis (such as speed, acceleration, stroke, etc.) meet the requirements.
Check the communication function: Test whether the communication between the positioner and the host computer is normal to ensure that the data is transmitted correctly.
Check the emergency stop function: Test whether the emergency stop button is working properly to ensure that the power can be cut off immediately in an emergency.
4. Sensor and encoder inspection
Check the encoder: Check whether the wiring of the encoder is loose, whether the encoder disk is contaminated, and whether the signal output is accurate.
Check the sensor: Ensure that the sensor is installed in the correct position and the signal transmission is normal.
5. Safety and protection device inspection
Check the overload protection device: Ensure that the overload protection device can work properly and automatically cut off the power when the current exceeds the set value.
Check the grounding device: Check whether the grounding of the equipment is reliable and whether the grounding wire is firm.
6. Regular maintenance
Cleaning and lubrication: Clean dust and debris on electrical components regularly to ensure good heat dissipation. Lubricate the parts that need lubrication.
Replace aging parts: Replace aging cables, terminals and other electrical components in time.
7. Debugging and testing
Functional test: Test whether the various functions of the equipment are operating normally, including motion control, welding synchronization and other functions.
Long-term load test: Perform a long-term load test to ensure that the equipment will not be overloaded or malfunction during long-term operation.
