Description
When the emulated encoder output (EEO) is configured to generate an index pulse (Z pulse) once per rev (DRV.EMUEMODE is 1, 6, or 8) this parameter and DRV.EMUEZOFFSET define the location of the Z pulse. DRV.EMUEZOFFSET defines the position of the Z pulse within one revolution. The pulse is generated each time this position is reached. For example, if this value is set to 32,768 (180 degrees), the Z pulse will be generated at 180 degrees, 540 degrees, 900 degrees, and so on.
When the EEO is configured to generate and absolute index pulse (DRV.EMUEMODE is 2,7, or 9) this parameter, DRV.,EMUEZOFFSET and DRV.EMUEMTURN define the location of the Z pulse. DRV.EMUEMTURN is used to define which turn of the position range the Z pulse is located. DRV.EMUEZOFFSET is used to define the position of the Z pulse within one revolution. For example, if DRV.EMUETURN is set to 1, and DRV.EMUEZOFFSET is set to 32,768 (180 degrees), then the index pulse will be generated at position 540 degrees.
When the EEO is configured in pass through mode (DRV.EMUEMODE is 12, 13, or 14) the EEO Z pulse will be generated each time the encoder's physical Z pulse is generated (the physical Z pulse is "passed through").
DRV.EMUEMODE sets the EEO connector to act as either an input or output as follows.

If you are using multi-turn or single tune absolute feedback devices, and the once per rev or absolute Z pulse modes (DRV.EMUEMODES 1,2,6,7,8, or 9) the Z pulse generated by the EEO will always be aligned with the same mechanical position of the primary feedback position. If you are using an incremental feedback device
A process whereby some proportion of the output signal of a system is passed (fed back) to the input.
In automation, a device coupled to each motor to provide indication of the motor's shaft angle, for use in commutating the motor and controlling its speed and position and these modes, then the origin of the primary feedback is not at the same mechanical position each time the drive powers up. If you are using the pass through mode (DRV.EMUEMODES 12, 13, or 14) the Z pulse generated by the EEO will always be aligned with the same mechanical position of the primary feedback position.
