BLDC with 8i20 and Fanuc Encoder

Hi,
I have a 8i20 drive connected to a Fanuc motor with a a64 serial encoder connected to a 7i44 board.
I have communication with the absolute encoder working, but I my question is with what signals to use with BLDC

The HAL Fanuc encoder module has a .comm pin that outputs a 0-1 float signal 4 times per motor rotation. This is the phase position and should be used to drive the motor.

But I am not sure how to get the 0-1 signal in to the BLDC module and what config mode to use.


Any help would be appreciated.
