Method (-5) Absolute encoder

These homing methods are suitable for absolute encoders (e.g. SSI-Multiturn encoders). Homing is performed immediately after power-on. The reference position is calculated on the basis of the encoder absolute position plus zero offset. In the case of a SSI multi-turn encoder, homing with zero point offset = 0 gives the absolute position of the SSI encoder. Another homing run with unchanged setting of the zero offset does not cause a change in position.
To set the machine reference point homing method (-12) should be used.

Methods (-4) and (-3) are not defined

Method (-2) No homing

No homing is performed. The current position is added to the zero offset. The first time the power stage is switched on the "Homing completed" status is set. This method is suitable for absolute encoders, as long as no offset compensation is required. For offset compensation select method (-5).

Method (-1) Actual position = 0

The actual position corresponds to the zero point; it is set to 0, meaning the controller performs an actual position reset. The zero offset is added.
