Function:

If this parameter is set to 1, homing has to be carried out before
any positioning can take place.
Function:
*
[-1,073,741,824,
...
This parameter defines an offset to the "zero" (HOME) position.
1,073,741,823 UU]
Any change in this setting will immediately affect the actual po-
sition displayed in par. 34-50.
Function:
*
[1...1000]
The home ramp time is defined as the time in milliseconds it
would take to ramp from stand¬still to the maximum allowed
velocity par. 32-80).
Function:
[–(value in P3280)...
The home velocity is entered here. Notice that the sign of the
*
(value
in
P3280)
velocity determines the direction in which the homing sequence
ERPM]
will be performed.
Function:
The drive moves to the reference switch (Input 4) with home
velocity (P3303), then reverses and slowly (at 30% of home
velocity) leaves the switch, subsequently moves to the next in-
dex pulse. The HOME position is defined as that index position.
Like "0" but without the search for the index position. Instead
the HOME position is defined as the position at which the ref-
erence switch goes low. After defining the HOME position the
drive is then ramped down with the home ramp (P3302) and
stopped.
Like "0" but without reversing before leaving the reference
switch. Rather the movement is slowly continued in the same
direction out of the switch.
Like "1" but without the search for the index position. Instead
the HOME position is defined as the position at which the ref-
erence switch goes low. After defining the HOME position the
drive is then ramped down with the home ramp (P3302) and
stopped.
