Mitsubishi origin regression method

1. Data setting type

This method is to set the current bearing as the origin. Therefore, at this time, no matter which direction the servo motor stops at, only the data setting type origin return is required, and now this direction is the origin direction. Therefore, in the origin regression operation under this method, the servo motor will not move!

2. This method can be used when the servo does not need to carry out the first value positioning, such as only speed control, torque control, or only incremental positioning.

3. In the servo parameters, the default setting condition is selected as "the demand needs to pass through the Z phase of the servo motor after the power supply is opened", so when performing this data setting origin regression, either this parameter is set to "the servo motor Z phase is not required after the power supply is open", or the first line JOG makes the servo motor roll more than one turn, and then performs the origin regression.

4. Near-point DOG type

What is Near Point DOG?

The near-point DOG is actually a sensor signal. We need to confirm the origin location, so how to confirm it? After JOG makes the servo motor roll, visually moves it to the direction we want, and then performs a data-set origin regression? This, of course, is very inaccurate.

5. So can we do this, add a mark when we want to confirm the direction of the origin, and then stop when the servo motor goes to this marked position, and specify the current orientation of the servo motor as the origin? Of course!

6. So, the near-point DOG signal is such a marker.
