Servo driver is common breakdown is analytic

Gain setting is too big, new hand is moved adjust gain or;b of function of use self-correcting gain.

Lengthen add slowdown time;c.

Laden and overweight, need new make choice of more the electric machinery of high capacity or reduce load, add the main transfer machinery such as outfit decelerate machine to increase bear capacity. Tally of electric machinery deviation happens to spill over in ③ moving process mistake. Countermeasure: A.

Increase deviation tally to spill over horizontal set is worth;b.

Decelerate rotate speed coming back to spend;c.

Lengthen add slowdown time;d.

Laden and overweight, need new make choice of more the electric machinery of high capacity or reduce load, add the main transfer machinery such as outfit decelerate machine to increase laden capacity. 2, servo electric machinery does not run when pulse is outputted, if why be handled? ① monitors the pulse of controller outputs current value and pulse output lamp to whether twinkle, affirm instruction pulse has been carried out and controller of inspection of ② of; of pulse of already normal output arrives the control cable of driver, dynamical cable, coder cable whether layout mistake, whether has its brake opened the servo electric machinery that damaged perhaps contacts examination of undesirable; ③ to take brake it is normal that; ④ monitors the face plate of servo driver affirms whether pulse instruction inputs; ⑤ Run to run an instruction mode of; ⑥ control chooses the position to control mode without fail, invert side drive inhibiting signal and signal of deviation tally restoration were not inputted, come away is laden and empty running is normal, examine mechanical system. 3, servo electric machinery did not take load to sign up for overload, if why be handled? If ① is servo Run(moves) signal receives and happen below the case that did not send pulse: A.

Check layout of cable of power of servo electric machinery, whether does the examination have a contact undesirable or cable damaged;b.

The servo electric machinery that if be,brings brake is sure to open brake;c.

Whether has speed return gain installed big;d.

Whether has been the integral time constant of speed loop installed small. ② if servo just happens in moving process: A.

Whether has positional return gain installed big;b.

Locate whether the amplitude that finish has installed small;c.

The examination does not have locked-rotor on axis of servo electric machinery, pay equal attention to to move whole mechanism newly. 4, unusual sound appears when servo electric machinery moves or shake phenomenon, if why be handled? ① servo layout: A.

Cable of use standard power, coder cable, control cable, cable has without damaged;b.

Whether does interference source exist near examination control line, whether to use power cable with the big electric current around mutual parallel or be apart are too close;c.

Whether does potential of examination earthing terminal have happen fluctuant, cogent make sure ground connection is good. ② servo parameter: A.

Servo gain setting is too big, the proposal is moved with the hand or;b of parameter of servo of automatic means readjust.

Affirm the setting of constant of time of speed feedback filter, initiative value is 0, can try to increase a setting to be worth;c.

Electronic gear wheel is too larger than the setting, the proposal restores to leave factory setting;d.

The resonance of servo and mechanical system, the attempt adjusts frequency of defect wave filter and amplitude. ③ mechanical system: A.

The shaft coupling of axis of join electric machinery and equipment system produces deflection, installation bolt did not screw;b.

Of pulley or gear occlusive and undesirable also can bring about laden torsion to change, try empty running, whether does if the union of mechanical system is checked normally when empty running,the part have unusual;c.

Affirm laden inertia, whether do pitching moment and rotate speed pass big, try empty running, if empty running is normal, reduce load or change more the driver of high capacity and electric machinery. 5, servo electric machinery does the position to control fixed position to forbid, if why be handled? Whether does current value mix the pulse that ① affirms to controller is given out actually above all the accord of expect, be like abhorrent the pulse that be checked and amends program; ② to monitor servo driver is received dictates a number is consistent, be like abhorrent whether is the setting that checks ③ of; of control line cable to examine pattern of servo instruction pulse installed consistently with controller, if CW/CCW still is pulse + setting of gain of servo of directional; ④ is too big, the attempt is moved with the hand afresh or automatic means adjusts electric machinery of servo of ⑤ of servo gain; easy when undertaking reciprocate generation accumulates an error, the proposal installs signal of a mechanical origin below the condition that craft allows, the search of ongoing travel origin that exceeds limit in the error operates precision of itself of system of; ⑥ machine not tall or main transfer machinery is discrepant constant (if servo electric machinery is mixed,the shaft coupling ministry between equipment system produces deflection to wait for) . 6, servo electric machinery does the position to control breakdown of moving newspaper overspeed, if why be handled? The layout that Run signal receives ① servo to produce; to check cable of power of servo electric machinery and coder cable is correct, have without damaged. After ② inputs pulse to dictate, happen when high speed moves: A.

The pulse frequency that controller outputs is too big, modification program adjusts the frequency;b that pulse outputs.

Electronic gear crosses big;c than the setting.

Servo gain setting is too big, the attempt is moved with the hand afresh or automatic means adjusts servo gain. CNC Milling
