Shanghai Yaoyou Repair Keyence Laser Scanner: Repair the small screen that does not light up when turned on, repair the system that cannot be accessed when turned on, repair errors when turned on, and repair faults when the black screen does not light up when powered on. Industrial equipment is repaired well and quickly. Our company's inventory of Keyence accessories and repair required accessories, modules, capacitors, chips, and other core accessories are all original and not easily damaged. Many of them are scrapped after repair. If repairs are needed, they can be sent to our company for processing. In addition, our company has complete online speedometers such as the Keyence simulation testing platform. With the addition of the Keyence repair team, we can ensure the success rate of Keyence visual controller repairs. With reasonable prices and good reputation, our company has gained recognition from peers and Keyence users

Example of High Frequency Fault Handling1. A.010 Overload Alarm Maintenance Points:-First, manually rotate the joint to check the mechanical resistance-Measure the resistance of the three-phase winding of the motor (normal value 0.5-2 Ω)-Check the lubrication status of the reducer
-If the above is normal, you can try to increase the overload alarm threshold appropriately (it is recommended not to exceed 120% of the original value)B. Special treatment for 050 joint exceeding the limit:-Enter maintenance mode and temporarily release the soft limitC. In depth investigation of 004 main power supply abnormality:-Measure input voltage (three-phase 380V ± 10%)-Check the contact resistance of the circuit breaker (should be less than 0.1 Ω)-Test the resistance value of the regenerative resistor (with a deviation of no more than 5% from the nominal value)-Check the capacitance capacity of the DC link (using a dedicated capacitance tester)
-Slowly move out of the limit position using jog mode-Check if the mechanical stopper has shifted-Re calibrate the zero position

Advanced Maintenance Techniques1. Emergency handling of encoder faults:When the A.020 encoder alarm occurs, you can try:-Re plug and unplug the encoder connector-Use an oscilloscope to check the waveform of the encoder signal-Temporary exchange of motors of the same model for testing-In the absence of spare parts, the parameters can be modified to switch the absolute value encoder to incremental mode for temporary operation
