# Offset to the homing position (P-AXIS-00279)

P-AXIS-00279 | Offset to the homing position
Description | If ‘OFFSET’ mode was selected to adopt the homing position in the parameter P-AXIS-00278 , enter the offset between the encoder position and the homing position in this parameter. The homing position to be set is calculated by: Homing position (axis position) = Encoder position + P-AXIS-00279.

Setting the homing position is triggered on the rising edge of the command element of the set_reference_position control unit. The value of P-AXIS-00279 at this instant is used to calculate the reference position.

Parameter | kenngr.set_refpos_offset
Data type | SGN32
Data range | MIN(SGN32) ≤ set_refpos_offset ≤ MAX(SGN32)
Axis types | T, R, S
Dimension | T: 0.1 µm | R,S: 0.0001°
Default value | 0
Drive types | ----
Remarks | Use of this parameter is only practical if the encoder delivers an absolute position.
