Siemens Torque Motor ERN Encoder adjustment

1. Unloading open motor rear cover, rear cover encoder

2. Release encoder mounting screws

4. Remove encoder, attention to handling the time to make use of special screws (which can produce their own one, seems to be 5mm of) top out to avoid damage to the encoder

Installation of encoder:

1, in the servo motor 45 degree angle where there is a sign of the circular depression (about 4 or 5mm in diameter is a look), while in the servo motor shaft is also a very significant mark, that this mark alignment the center of a circular mark, even if the motor shaft mark mark center circle coincides with that (we remember marking 1). To start the installation after the encoder.

2, in the encoder inside a tag (from the back of the encoder to look forward, to look very carefully, possible encoder of this tag may not be clear), while outside of the encoder (from the back look to the future can be saw) also has a flag, the encoder mark these two overlap (remember to tag 2), and then you can put on the servo motor encoder according to the (Note: The installation must be to make a mark and tag two overlap). In short, that is, so that the four markers coincidence!

The above are my personal installation process. After installation using normal. If the installation appears on the screen after the soft-limit alarm (both displayed on the screen is larger than the value of Axis-specific machine data parameters (if yes MD36100) set the soft limit value will appear when the alarm), then we have need to shake hands on the back of the shaft prior to demolition of the value on the screen.

Here are some book information, may be appropriate to do reference.

1. Unloading open motor rear cover, rear cover encoder

2. Release encoder mounting screws

3. Rotating rotor shaft, so that the encoder rotor encoder on the signs and marks on the shell overlap

4. Remove encoder, attention to handling the time out to make use of a special screw top to avoid damage to the encoder

5. Rotation of new encoders, so that the two signs coincide encoder

6. According to the above reverse order to install the encoder

Note: In the process of installing the encoder, to ensure that the rotor different, otherwise they will lose the relative position of the rotor, if the loss of the relative position of the old motor will need to use the oscilloscope to adjust the installation position of the encoder, the new motor can be based on a sign of rotor shaft to adjust the encoder to determine the installation location, which can be mechanical adjustments, you can also adjust the drive parameters MD1016 to set an offset value, but the method can only be used in the 840D, through this method to adjust the motor change to other machine tool use may be due to the different driving parameters can not work properly.
