Abstract

The invention discloses a Siemens AC servo motor encoder zero setting method. The method at least needs the following tools: a signal cable, an oscilloscope and a DC power supply. Comprising the following steps: grounding a Siemens servo motor; connecting a signal wiring terminal of the servo motor to a signal input end of an oscilloscope through a signal cable, and connecting an alternating current wiring terminal of the servo motor to a direct current power supply; and the waveform of the oscilloscope is controlled and adjusted, so that zero setting of the encoder is realized. The invention further discloses a verification method of the encoder zero setting method. The method is simple to operate, the zero setting precision is controlled within the range of + / -0.1 degrees, the performance of the motor is restored, and meanwhile the maintenance cost and period are greatly reduced.

Description

technical field

[0001] The invention relates to the technical field of numerical control maintenance, in particular to a method for zeroing an encoder of a Siemens AC servo motor and a calibration method. Background technique

[0002] AC servo motors are widely used in CNC machine tools, intelligent robots, digital production lines and other fields. They have the characteristics of high position accuracy, stable performance and reliable operation. The damage and dirt of the precision glass code disc of the internal encoder of the AC servo motor are the most common faults of the AC servo motor. The fault will directly cause the AC servo motor to stop, and then cause the equipment to be paralyzed.

[0003] At present, the replacement and adjustment technology of debugging AC servo motor encoders is in the hands of motor manufacturers and a small number of professional servo motor repair manufacturers. Servo motors that fail due to encoder problems must be repaired by them usin...
