Repair the Keyence Safety Lidar, which cannot enter the system when turned on

Shanghai Yaoyou Electric Co., Ltd. specializes in repairing Keyence Safety Lidar systems that cannot be accessed during startup. Our company specializes in repairing Keyence Lidar and Keyence Laser Scanners, as well as repairing industrial equipment quickly and effectively. Our inventory includes various series of Keyence accessories and core components such as modules, capacitors, and chips, all of which are 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's Keyence laser radar simulation testing platform and other online speedometers are complete. With the addition of the Keyence repair team, we can ensure the success rate of laser radar repairs. Our company has gained recognition from peers and users with reasonable prices and good reputation

Software diagnosis**
-Read real-time current curves using Sinano specialized debugging software (such as SN Configurator) and analyze the specific operating conditions where overcurrent occurs (such as acceleration/deceleration stages).Maintenance plan and practical case study
####Case 1: Power module breakdown
-Phenomenon: The driver reports overcurrent when powered on and cannot be reset.
-* * Processing * *:
1. After dismantling, it was visually observed that there were burn marks on the IGBT module. Replace it with a module of the same model (such as FF300R12KE3).
2. Check if the optocoupler of the drive circuit (such as HCPL-316J) is damaged, replace it, and test that the drive signal is normal.
3. After repair, the offset of the current sensor needs to be recalibrated to avoid sampling errors.Case 2: Parameter configuration error

-Phenomenon: The device frequently trips during high-speed operation, but operates normally at low speeds.
Repair the Keyence Safety Lidar, which cannot enter the system when turned on-* * Processing * *:
1. Upon inspection, it was found that the integration time (Ti) of the speed loop was set too small, resulting in dynamic response overshoot.
2. Gradually adjust the parameters: reduce the speed gain (Kv) from 120% to 80%, and extend the integration time from 50ms to 100ms.
After the load inertia ratio is re matched, the fault is eliminated.
