1, high speed motor deviation counter overflow error occurs when revolving. countermeasures: check the motor power cable and encoder cable wiring is correct, cable to see if there is any breakage. 2, in the process of running motor deviation counter overflow error. countermeasures: increase the error counter overflow level set point; Slow down the rotating speed; Prolonged deceleration; Under the heavy load, needs to be selected more large capacity motor or lighten the load, adding speed reducer drive mechanism, such as improve the load capacity. 3, servo motor output pulse is not running, how to deal with? a, monitoring the pulse output current value of the controller and pulse output light is flashing, confirm instruction pulse has executed and have normal output pulse; b, check the controller to drive the control cable, power cable, whether encoder cable wiring error, damage or poor contact. c, check whether the servo motor with brake the brake is already open. Monitor the panel of the servo drive confirm whether pulse command input; d, running commands Run normally; e, control mode, be sure to select the position control mode; f, servo drive Settings of the input pulse type and instruction pulse Settings are consistent; c, ensure side (are) driving ban, reverse side driving ban signal and deviation counter reset signal is not input, release load and no-load running normal, check the mechanical system. 4, servo motor without load overload, how to deal with? if the servo Run (Running)Signal access and there is no one under the condition of pulse: check the servo motor power cable wiring, check whether there is a poor contact or cable damage; If it's with a brake servo motor, be sure to open the brake; Whether the speed loop gain setting is too large; Integral time constant of speed loop is set too small. if the servo is in the process of running: the position loop gain is set too large; Positioning to complete amplitude is set too small; Check the servo motor shaft is not blocked, and to adjust the machine. 5, the abnormal sound or servo motor run time jitter phenomenon, how to deal with? Servo wiring:
use the standard power cable, encoder cable, control cable, cable with and without damage; Check whether there is interference sources, near line and high-current power cables near parallel to each other or apart too close; Check the earthing terminal potential for change, and ensure good grounding. Servo parameters:
servo gain setting is too big, suggest using manual or automatic way to adjust the servo parameters; Confirm time constant of speed feedback filter set, the initial value of 0, can try to increase the setting values; Electronic gear is set too big, it is recommended that back to the factory Settings; Servo system and mechanical system resonance, try to adjust the notch filter frequency and amplitude. Mechanical system:
to connect the motor shaft and coupling of equipment system migration, mounting screw is not tight; Pulley or gear bite bad will cause a change in the load torque, try running light, if no-load running normally, to check whether there is abnormal in combination with part of the mechanical system; Confirm the load inertia, torque and rotate speed is too large, try running light, if no-load running, it lighten the load or replaced and larger capacity drives the motor. 6, servo motor position control positioning mustn't, how to deal with? first to determine whether the controller actually emitted pulse current value is the same as expected, such as inconsistency check and correction procedures; monitor servo driver receives the number of pulse instruction whether issue is consistent and controller, such as inconsistency check the line of control cables; Check whether servo command pulse mode Settings and the controller Settings must agree, such as the CW/CCW or pulse + direction; servo gain setting is too big, try to use manual or automatic way to adjust the servo gain; Servo motor on the cumulative error caused by the reciprocating motion, suggested that under the condition of process allows to set up a mechanical origin signal, before the error is beyond the scope allowed for the origin search operation; Mechanical system itself precision is not high, or transmission mechanism have exceptions (Such as servo motor and equipment system of the coupling between the offset, etc. )。 7, servo motor position control malfunction to speeding, how to deal with? a servo Run signal access occurs: check the servo motor power cable and encoder cable wiring is correct, have without damage. when running at high speed before and after the input pulse instruction: the controller of the output pulse frequency is too large, modify the program to adjust the frequency of the pulse output. Electronic gear ratio too large; Servo gain setting is too big, try to use manual or automatic adjustment of servo gain. 8, a longer input command pulse motor deviation when the counter overflow error. countermeasures: gain setting is too big, to manually adjust the gain or using automatic adjust gain function; Prolonged deceleration; Under the heavy load, needs to be selected more large capacity motor or lighten the load, adding speed reducer drive mechanism, such as improve the load capacity.
