4.3.2 Dog mode home posi tion return
In this mode, instead of the encoder Z-phase(Fig. 4-6), the DOG sig nal is used to switch from
“home posi tion return speed” PC04 to “creep speed” PC05. You can use param e ter PD16 “prox -
im ity dog detec tion polar ity” to spec ify whether a log i cal “1” or a log i cal “0” should be iden ti fied as
an active DOG sig nal.
As in a above, the phys i cal home posi tion can be shifted in rela tion to the home (zero) posi tion
of the encoder (Z-phase) with PC06 “home posi tion off set (shift)”. In addi tion to this you can also
set a non-zero coor di nate for the home posi tion with PC07.
Con di tions for the prox im ity dog signal:
The prox im ity dog sig nal (DOG) must ful fill the fol low ing con di tions to ensure that the Z-phase of
the encoder is detected dur ing the acti va tion period of the DOG sig nal:
