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.

2.如何解決伺服電機高速旋轉時出現(xiàn)電機偏差計數器溢出錯誤的問題？
A
當伺服電機高速旋轉時，電機偏差計數器出現(xiàn)溢出錯誤。

失效分析：
-增益設置太大，再次手動調整增益設置或使用自動調整增益設置功能；
-延長加速/減速時間；
-負載太重，有必要選擇更大容量的另一臺電機或減少負載，安裝減速器或其他驅動機構，以提高負載能力。
運行期間電機偏差計數器發(fā)生溢出錯誤。
失效分析：
-增加偏差計數器的超限水平設定值；
-降低轉速；
-延長加速/減速時間；
-負載太重，有必要選擇更大容量的另一臺電機或減少負載，安裝減速器或其他驅動機構，以提高負載能力。
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.如何解決伺服電機在無負載情況下，運行時報告過載的問題？
A
如果在伺服運行信號存取且沒有脈沖時發(fā)生該情況：
-檢查伺服電機電源電纜的接線是否接觸不良或電纜是否有損壞；
-對于帶制動器的伺服電機，請始終打開制動器；
-速度電路增益是否設置太大；
-速度電路的積分時間常數是否設置太大。
如果條件只發(fā)生在操作過程中：
-位置電路增益是否設置太大；
-定位完成幅度是否設置太小；
-檢查伺服電機軸沒有堵轉失速并再次調整機械系統(tǒng)。
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.如何解決伺服電機運轉時出現(xiàn)異常噪音或晃動的問題？
A
伺服接線：
-使用標準電源電纜，編碼器電纜和控制電纜，并檢查電纜是否有損壞；
-檢查控制線附近是否有干擾源，以及線路是否平行或靠近大電流電力電纜；
檢查接地端子電位是否發(fā)生變化，并確保接地狀況良好；
伺服參數：
-伺服增益設置得太大，建議再次使用手動或自動方式調整伺服參數；
-確認速度反饋濾波器的時間常數設為0作為初始值并嘗試增加設定值；
-電子齒輪比設置得太大，建議恢復出廠設置；
-伺服系統(tǒng)與機械系統(tǒng)共振，嘗試調整陷波濾波器的頻率和幅值。
機械系統(tǒng)：
-連接電機軸和設備系統(tǒng)時出現(xiàn)偏差，安裝螺絲未擰緊；
-皮帶輪或齒輪嚙合不良也可能導致負載轉矩改變，嘗試空載運行。如果系統(tǒng)空載運行正常，請檢查機械系統(tǒng)的嚙合部分是否有異常。
-確認負載慣量，扭矩和速度是否過大。嘗試空載運行。如果系統(tǒng)沒有負載正常運行，請減小負載或更換大容量的其他驅動器和電機。
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.

Q
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.
