How to reset the zero position of absolute encoder

Rotary encoders sometimes have zero offsets while they are working, which makes it impossible to calculate and operate correctly. Then, how to reset the zeros after the zero offsets of the rotary encoders? okplazas.com editor online I found a strong technical post that broke down the steps of the operation in detail for your reference.

Netizen asked: Siemens 840D CNC system, the Z axis was turned on in the morning and found the zero offset, which is a full 1.6 meters. I am using an absolute encoder, and now I want to reset the zero position, how can I do it?

Technical Answer: You can reset to zero, the steps are as follows:

1. Find the mechanical position of the zero point;

2. Set the machine data MD34200-ENC_REEP_MODE of the Z axis to 0 (ENC_REEP_MODE=0 indicates that the actual value of the axis is set once);

3. NCK reset makes the data effective;

4. Manually move the Z axis to the zero mechanical position in JOG mode;

5. Input data 0 into the Z-axis machine data MD 34100-REEP_SET_POS;

6. Set the machine data MD34210-ENC_REEP_STATE to 1 (in order to activate the "adjustment" function);

7. NCK reset makes the data effective;

8. Convert the system to JOG_REF mode (back to reference point mode);

9. By pressing the positive direction key (MD34010=0) (or negative direction key (MD34010=1)) of the axis, the value of machine data MD34100 can be input into machine data MD34090-REEP_MOVE_DIST_CORR and MD34210-ENC_REEP_STATE becomes "2" ";

10. Exit the JOG_REF mode, the zero point reset is complete.

I hope that the above detailed operation steps sharing can give friends who are solving the zero offset of this rotary encoder a little help, if you can't solve the problem, you still find the supplier to provide help to solve it.
