??Breaking the motor cover, the back cover of the encoder;
??Loosen the the encoder mounting screws;
??Rotating the rotor shaft, the flag in the flag on the rotor of the encoder and the encoder casing coincide PCBs & Manufacturing Services;
??4 Remove the encoder, pay attention to make use of the special screws in the loading and unloading of the top out, lest damage the encoder;
??Rotating a new encoder, the encoder of the two flags coincide;
??6 above in reverse order to install the encoder;
??Note: in the process of installation of the encoder, it is necessary to ensure the rotor of the motor, otherwise they will lose the relative position of the rotor If lost relative location, old motor you need to adjust the installation position of the encoder with an oscilloscope,
??New motor can be determined based on the sign of the motor rotor shaft to adjust the mounting position of the encoder when, i.e. mechanical adjustment drive parameters MD1016 to set an offset value can also be adjusted, but the method can only be used in the 840D
??By this method to adjust the motor for use on another machine may drive different parameters can not be used normally.
??Second, the zero adjustment
??Adjust the following steps: startup - ? machine data - ? Axis
??MD - ? to adjust the parameters: 34100 (axis reference coordinate value) correction, if the change after the now and the original difference of 10mm, set a parameter 34,100 raised to 10. You can also modify 34090 (reference point offset): zero with zero difference between the number of imported.
??Third, the power module simple test methods:
??Since the main components of the power module is a high-power tube roughly detection power tube is good or bad, you can use the following methods:
??Multimeter to hit resistance profile pen multimeter positive table received the power module DC voltage input terminal P600, and received a three-phase power output of the power tube U2, V2, W2 resistance should infinity
??Exchange the two tables multimeter pen, resistance should be rare. Received a multimeter table pen M600, repeat the above process, the result should be the opposite and above.
