# Homing without reversal

## Referencing in 1 phase

Referencing in one phase is executed without change in direction

Examples for translatory axes

## Attention

Referencing in one phase is optional but should not be used in reality. Please note here that the axis many not be located on the reference cam at the start of homing.

This check is executed by the PLC.

Parameterisation | P-AXIS-00156 (ref_ohne_nocken) | 0, reference cam present
| P-AXIS-00084 (homing_without_zero_pulse) | 0, with zero pulse
| P-AXIS-00157 (ref_ohne_rev) | 1, no reversal

## Referencing with zero pulse

Move to reference cam with zero pulse (1 phase)

## Referencing without zero pulse

Parameterisation | P-AXIS-00156 (ref_ohne_nocken) | 0, reference cam present
| P-AXIS-00084 (homing_without_zero_pulse) | 1, no zero pulse
| P-AXIS-00157 (ref_ohne_rev) | 1, no reversal

Move to reference cam without zero pulse (1 phase)
