Q

1. Servo motor does not run when the pulse is output, how to solve the problem?

A

-Monitor the current pulse output value of controller and check if pulse output indicator lamp flashes to confirm that the controller has performed command pulse and has output pulse normally.

-Check if the control cable, power cable, encoder cable between controller and driver are matched incorrectly damaged or contacted poorly.

-Check if the brake of servo motor equipped with brake has been turned on.

-Monitor the panel of servo driver to confirm if the pulse command has been input.

-Run command is normal.

-For control mode, always choose position control mode.

-Check if the type of input pulse set by servo driver matches with that of command pulse.

-Ensure that positive side drive prohibition, negative side drive prohibition signals and deviation counter reset signal are not input and the servo motor runs normally if load is removed, then check the mechanical system.

Q

2.如何解决伺服电机高速旋转时出现电机偏差计数器溢出错误的问题？

A

当伺服电机高速旋转时，电机偏差计数器出现溢出错误。

失效分析：检查电机电源电缆和编码器电缆的配线是否正确以及电缆是否有损坏；

当输入更长的命令脉冲时，电机偏差计数器出现溢出错误。

失效分析：

-增益设置太大，再次手动调整增益设置或使用自动调整增益设置功能；

-延长加速/减速时间；

-负载太重，有必要选择更大容量的另一台电机或减少负载，安装减速器或其他驱动机构，以提高负载能力。

运行期间电机偏差计数器发生溢出错误。

失效分析：

-增加偏差计数器的超限水平设定值；

-降低转速；

-延长加速/减速时间；

-负载太重，有必要选择更大容量的另一台电机或减少负载，安装减速器或其他驱动机构，以提高负载能力。

Q

2. How to solve the problem that overrun errors occur in motor deviation counter when servo motor rotates at high speed?

A

Overrun errors occur in motor deviation counter when servo motor rotates at high speed.

Countermeasure:

Check if wirings of motor power cable and encoder cable match correctly and if there is any damage in cables.

Overrun errors occur in motor deviation counter when much longer command pulse is input.

Countermeasure:

-Gain setting is too large. Manually adjust gain setting again or use automatic adjustment gain setting function.

-Prolong the acceleration/deceleration time.

-The load is too heavy. It is necessary to choose another motor with larger capacity or reduce the load, install speed reducer or other drive mechanism, so as to improve load capacity.

Overrun errors occur in motor deviation counter during operation.

Countermeasure:

-Increase the overrun level set value of deviation counter.

-Reduce the rotation speed.

-Prolong the acceleration/deceleration time.

-The load is too heavy. It is necessary to choose another motor with larger capacity or reduce the load, install speed reducer or other drive mechanism, so as to improve load capacity.

Q

3.如何解决伺服电机在无负载情况下，运行时报告过载的问题？

A

如果在伺服运行信号存取且没有脉冲时发生该情况：

-检查伺服电机电源电缆的接线是否接触不良或电缆是否有损坏；

-对于带制动器的伺服电机，请始终打开制动器；

-速度电路增益是否设置太大；

-速度电路的积分时间常数是否设置太大。

如果条件只发生在操作过程中：

-位置电路增益是否设置太大；

-定位完成幅度是否设置太小；

-检查伺服电机轴没有堵转失速并再次调整机械系统。

Q

3. How to solve the problem that overload is reported when servo motor runs without any load?

A

If the condition occurs when servo run signal is access and there is no pulse:

-Check if the wiring of servo motor power cable is contacted poorly or there is any damage in cable.

-For servo motor with brake, always turn on the brake.

-If the speed circuit gain is set too large.

-If the integral time constant of speed circuit is set too large.

If the condition only occur during operation:

-If the position circuit gain is set too large.

-If the locating completion amplitude is set too small.

-Check that there is no stall on servo motor shaft and adjust the mechanism system again.

Q

4.如何解决伺服电机运转时出现异常噪音或晃动的问题？

A

伺服接线：

-使用标准电源电缆，编码器电缆和控制电缆，并检查电缆是否有损坏；

-检查控制线附近是否有干扰源，以及线路是否平行或靠近大电流电力电缆；

检查接地端子电位是否发生变化，并确保接地状况良好；

伺服参数：

-伺服增益设置得太大，建议再次使用手动或自动方式调整伺服参数；

-确认速度反馈滤波器的时间常数设为0作为初始值并尝试增加设定值；

-电子齿轮比设置得太大，建议恢复出厂设置；

-伺服系统与机械系统共振，尝试调整陷波滤波器的频率和幅值。

机械系统：

-连接电机轴和设备系统时出现偏差，安装螺丝未拧紧；

-皮带轮或齿轮啮合不良也可能导致负载转矩改变，尝试空载运行。如果系统空载运行正常，请检查机械系统的啮合部分是否有异常。

-确认负载惯量，扭矩和速度是否过大。尝试空载运行。如果系统没有负载正常运行，请减小负载或更换大容量的其他驱动器和电机。

Q

4. How to solve the problem that abnormal noise or shaking occurs when servo motor is running?

A

Servo wiring:

-Use the standard power cable, encoder cable and control cables and check if there is any damage in cables.

-Check if there is any interference source near the control wires and if the wires are parallel or too close to nearby

high current power cables.

-Check if ground terminal potential has changed and ensure that grounding is in good condition.

Servo parameter:

-Servo gain is set too large. It is suggested to use manual or automatic way to adjust servo parameter again.

-Confirm that time constant for speed feedback filter is set at 0 as initial value and attempt to increase the set value.

-Electronic gear ratio is set too large. It is suggested to restore the factory setting.

-The servo system resonates with the mechanical system. Attempt to adjust the frequency and amplitude of notch filter.

Mechanical system:

-Deviation occurs in coupling connecting motor shaft and equipment system and mounting screws are not tightened firmly.

-Poor engagement of pulley or gear may also cause load torque change. Attempt to run without load. If the system operates normally without load, check if the engaged part of mechanical system has any abnormality.

-Confirm if load inertia, torque and speed are too large. Attempt to run without load. If the system operates normally without load, reduce the load or replace another driver and motor with large capacity.

5. How to solve the problem that the position control positioning of servo motor is inaccuray?

A

First confirm if the current pulse value actual sent from controller is the same as anticipated. If not, perform inspection and correct the procedure.

Monitor if the number of pulse commands received by servo driver matches that from controller. If not, check the control wire cable.
