SB822机器人伺服电机修理几种故障没有带负载报过载，怎么处理假如是伺服Run（运转）信号一接入而且没有发脉冲的情况下发作：
查看伺服电机动力电缆配线，查看是否有接触不良或电缆破损；假如是带制动器的伺服电机则必须将制动器翻开；速度回路增益是否设置过大；速度回路的积分时间常数是否设置过小。假如伺服只是在运转过程中发作方位回路增益是否设置过大；定位完成幅值是否设置过小；查看伺服电机轴上没有堵转，并从头调整机械。                         

6、ABB机器人伺服电机修理几种故障运转时出现反常声音或颤动现象，怎么处理？
伺服配线：
运用规范动力电缆，编码器电缆，操控电缆，电缆有无破损；查看操控线附近是否存在干扰源，是否与附近的大电流动力电缆互相平行或相隔太近；查看接地端子电位是否有发作变化，实在确保接地杰出。

伺服参数：
伺服增益设置太大，主张用手动或主动方法从头调整伺服参数；承认速度反应滤波器时间常数的设置，初始值为0，可测验增大设置值；电子齿轮比设置太大，主张恢复到出厂设置；伺服体系和机械体系的共振，测验调整陷波滤波器频率以及幅值。

机械体系：
衔接电机轴和设备体系的联轴器发作偏移，安装螺钉未拧紧；滑轮或齿轮的咬合不良也会导致负载转矩变化，测验空载运转，假如空载运转时正常则查看机械体系的结合部分是否有反常；承认负载惯量，力矩以及转速是否过大，测验空载运转，假如空载运转正常，则减轻负载或替换更大容量的驱动器和电机。本特利bently3500在钢铁电力化工石化行业的应用和振动监测的测点

ABB Robot Servo motor repairs several faults and does not work when there is pulse output. How to deal with them?

Monitor the current value of the pulse output of the controller and whether the pulse output lamp flashes, and acknowledge that the command pulse has been fulfilled and the pulse has been output normally; Check whether the control cable, power cable and encoder cable from the controller to the driver are wrongly wired, damaged or in poor contact; Check whether the brake of servo motor with brake has been opened; Monitor whether the panel of the servo driver acknowledges whether the pulse command is input; The run command is normal; The control form must select the azimuth control form; Whether the input pulse type set by the servo driver and the setting of the command pulse are common; Make sure that the driving stop signal of the positive rotation side, the driving stop signal of the rotation side and the reset signal of the error counter are not input, and the load is disconnected and the no-load operation is normal. Check the mechanical system.



2. ABB Robot Servo motor repairs several faults. When the motor error and counter overflow occur during high-speed rotation, how to deal with them?



Motor error counter overflow fault occurs during high-speed rotation.

Countermeasures: check whether the wiring of motor power cable and encoder cable is correct and whether the cable is damaged.



The motor error counter overflow fault occurs when a long command pulse is input.

Countermeasures: if the gain setting is too large, manually adjust the gain from the beginning or use the active gain adjustment function; Extend the acceleration and deceleration time; If the load is too heavy, it is required to select a motor with larger capacity from the beginning or reduce the load, and install a reducer and other drive organizations to improve the load capacity.



Motor error and counter overflow fault occurred during operation.

Countermeasures: increase the overflow level setting value of the error counter; Slow down the rotation speed; Extend the acceleration and deceleration time; If the load is too heavy, it is required to select a motor with larger capacity from the beginning or reduce the load, and install a reducer and other drive organizations to improve the load capacity.



3. ABB Robot Servo Motor repair is not accurate in azimuth control and positioning. How to deal with it?

Firstly, confirm whether the current value of the pulse actually announced by the controller is the same as expected. If not, check and correct the program;

Monitor whether the number of pulse commands received by the servo driver is the same as that announced by the controller; if not, check the control line cable; Check whether the setting of servo command pulse form is the same as that of the controller, such as CW / CCW or pulse + direction;

If the servo gain setting is too large, adjust the servo gain manually or actively from the beginning of the test; When the servo motor is reciprocating, it is easy to generate accumulated errors. It is proposed to set a mechanical origin signal under the conditions allowed by the process, and conduct the origin search operation before the error exceeds the allowed scale; The accuracy of the mechanical system itself is not high or the transmission organization is abnormal (for example, the coupling between the servo motor and the equipment system is offset).



4. ABB Robot Servo Motor repair do azimuth control operation report overspeed fault, how to deal with it?

Once the servo run signal is connected, it will break out: check whether the wiring of servo motor power cable and encoder cable is correct and whether there is damage.

After inputting the pulse command, it occurs during high-speed operation: the pulse frequency output by the controller is too high, and the correction program adjusts the frequency of the pulse output; The electronic gear ratio is set too large; The servo gain setting is too large. Adjust the servo gain manually or actively from the beginning
