Incremental Encoder HMZ

I am setting up a machine that has 18 axes. I am using incremental encoders for axes 1-9 and analog inputs for axes 10-18. I am also using 2 additional incremental encoders for Master Following on axes 8 & 9. These incremental encoders are hooked into the encoder slots of axes 10 & 11 and then mapped to the slaved axes (Ixx05). Everything works perfect with the master following enabled, and I can see the output of the encoders as they move.

 

My problem is that I sometimes need to zero out the 2 additional incremental encoders. A regular HMZ only affects the analog input for 10 & 11, and not the encoders. How can I zero out the additional encoders I have installed and not affect my axes 10 & 11?

 

Encoder table definition below for reference. Entry 10 and 11 are the additional incremental encoders that are mapped for master following (I805=$350A, I905=$350B).

Unused motors could be assigned to the master encoders, e.g. I1903 = $3508 I1904=$3508 I2003=$3509 I2004=$3509. Then, #19Hmz and #20Hmz would zero Master position, as seen in positions of motors 19 and 20.

 

Note that that approach zeroes the motor positions of the masters, not the encoder positions. Encoder positions can only be zeroed by reset or power cycling. If, for some reason, you want to be able to zero the master position in the ECT, the actual position register of the master could be entered in the ECT and used for following....
