Home position offset = 0 (case 2)
The zero pulse has not yet occurred during the homing process (e.g. in case of incremental encoders,
the position is only determined after one revolution):

Fig. 2−11 Approaching the home position (case 2)
If the parameter setting or the position of the reference switch have been selected unfavourably, the
drive is unable to directly approach the home position due to a too high moment of inertia. This means
that the drive travels beyond the home position and then back again.
Reversing during the homing process can be prevented by setting the home position offset so that
the path is long enough to decelerate into standstill. The reference switch and the subsequent zero
pulse must be brought forward accordingly.
