I have EtherCAT AC Servos with 23-bit multi-turn absolute encoders. I am trying to configure my "home" position. Is there a definitive documentation on using absolute encoders?
My absolute location is not where I want G53 "home" to be, in the case of the below and the provided INI sniplet, it's 7.3033 inches from the zero location I want. Reading the documentation, it states to set HOME_OFFSET, and I also see a forum posts to set HOME. I feel like I am just guessing. I have tried both, and neither works. Also, I should never have to "home" the axis, correct?

MAX_VELOCITY = 2
MAX_ACCELERATION = 4
MIN_LIMIT = -9.0000
MAX_LIMIT = 9.0000
