ABB机器人伺服电机修理做方位操控定位不准，怎么处理？
首要承认操控器实际宣布的脉冲当时值是否和料想的共同，如不共同则查看并修正程序；
监督伺服驱动器接收到的脉冲指令个数是否和操控器宣布的共同，如不共同则查看操控线电缆；查看伺服指令脉冲形式的设置是否和操控器设置得共同，如CW/CCW还是脉冲+方向；
伺服增益设置太大，测验从头用手动或主动方法调整伺服增益；伺服电机在进行往复运动时易产生累积差错，主张在工艺答应的条件下设置一个机械原点信号，在差错超出答应规模之前进行原点查找操作；机械体系本身精度不高或传动组织有反常（如伺服电机和设备体系间的联轴器部发作偏移等）。

4、ABB机器人伺服电机修理做方位操控运转报超速故障，怎么处理？
伺服Run信号一接入就发作：查看伺服电机动力电缆和编码器电缆的配线是否正确，有无破损。
输入脉冲指令后在高速运转时发作：操控器输出的脉冲频率过大，修正程序调整脉冲输出的频率；电子齿轮比设置过大；伺服增益设置太大，测验从头用手动或主动方法调整伺服增益 

5、ABB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。
How to deal with inaccurate azimuth control and positioning during ABB robot servo motor repair?

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

Supervise 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 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, test to adjust the servo gain manually or actively from the beginning; 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 allowable 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. How to deal with the overspeed fault reported by ABB robot servo motor maintenance for azimuth operation?

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

After the pulse command is input, it occurs at high speed: 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. Test to adjust the servo gain manually or actively from the beginning



5. How to deal with several failures of ABB robot servo motor that are not reported overload with load?



If the servo Run signal is connected and no pulse is sent:

Check the power cable wiring of the servo motor to see if there is poor contact or cable damage; If it is a servo motor with brake, the brake must be turned over; Whether the speed loop gain is set too large; Whether the integral time constant of the speed loop is set too small.



If the servo only occurs during operation:

Whether the gain of azimuth loop is set too large; Whether the amplitude of positioning completion is set too small; Check that there is no locked rotor on the servo motor shaft, and adjust the machine from the beginning.



6. How to deal with the abnormal sound or vibration of ABB robot servo motor when it runs in repair of several faults?

Servo wiring:

Whether the power cable, encoder cable, control cable and cable are damaged; Check whether there are interference sources near the control line and whether they are parallel or too close to the nearby high current power cables; Check whether the potential of the grounding terminal changes suddenly to ensure excellent grounding.
