33-00 Force HOME
Option:
Function:
[0]
*
Home not forced
[1]
*
Home forced
If this parameter is set to 1, homing has to be carried out before
any positioning can take place.
33-01 Home offset
Range:
Function:
0 UU
*
[-1,073,741,824, …
1,073,741,823 UU]
This parameter defines an offset to the “zero” (HOME) position.
Any change in this setting will immediately affect the actual po-
sition displayed in par. 34-50.
33-02 Home ramp time
Range:
Function:
10 ms
*
[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).
33-03 Home velocity
Range:
Function:
100
ERPM
*
[–(value in P3280)…
(value in P3280)
ERPM]
The home velocity is entered here. Notice that the sign of the
velocity determines the direction in which the homing sequence
will be performed.
33-04 Home type
Option:
Function:
[0]
*
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.
[1]
*
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.
[2]
*
Like “0” but without reversing before leaving the reference
switch. Rather the movement is slowly continued in the same
direction out of the switch.
[3]
*
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.
