19-19 FFVEL Auto-calculation
Option:
Function:
[0]
*
Disabled
Automatic calculation is disabled for both
velocity feed forward (FFVEL) and velocity
control loop (PID).
[1]
FFVEL
enabled
The optimal setting of parameter velocity feed
forward is calculated automatically. This
parameter automatically resets to
[0] Disabled
when the calculation is complete.
[2]
FFVEL +
PID
enabled
The optimal setting of parameter velocity feed
forward, proportional, derivative, and integral
factor is calculated automatically. This
parameter automatically resets to
[0] Disabled
when the calculation is complete.
Parameter
32-80 Maximum Velocity
Parameter
32-00
OR
32-02 Encoder type
Parameter
32-01
OR
32-03 Encoder resolution
Parameter
19-14 motor/encoder gear ratio
numerator
Parameter
19-15 motor/encoder gear ratio
denominator
NOTICE
A change to any one of these parameters prompts a
recalculation, since the optimum value of the regulation
parameters has changed.
19-20 Factory Reset
Option:
Function:
[0]
*
Disabled No parameters reset.
[1]
Enabled Resets all parameter values to default and also
resets all trajectory data. The parameter automat-
ically resets to
[0] Disabled
when the reset is
successfully carried out.
19-21 Link LCP Input to Index
Option:
Function:
[0]
*
Disabled Disables the automatic update of parameter
19-23 Index Number
. This is necessary when
programming a position number different from
the one loaded into the PLC memory.
[1]
Enabled Parameter
19-23 Index Number
is automatically
updated with the last position reference number
that has been loaded into memory. This enables
the operator to see what position reference is
given by the PLC system.
19-23 Index Number
Range:
Function:
0 [0–31
(0–63 in
fieldbus
mode)]
Specifies which position data should be
displayed in parameters
19-24 Index Target
Position
to
19-28 Index Trajectory Type
. Whenever
this number is changed, the current values of
the index parameters are stored in the memory
under the previously specified index number.
After that, the values of the index parameters
are updated with the data stored in the memory
relevant to the newly specified index number.
19-24 Index Target Position
Range:
Function:
0 [–
1073741824
to
1073741824
UU]
The meaning of this parameter depends on
the position type specified in parameter
19-28
Trajectory Type
.
If parameter
19-28 Index Trajectory Type
=
[0]
Absolute
, the value of this parameter refers to
an absolute position (relative to the fixed
Home
position).
If parameter
19-28 Index Trajectory Type
=
[1]
Relative
, and the last position was obtained
through jogging, the value of this parameter
is a position relative to that position. If the
last position was reached as a result of a
positioning command, then the value of this
parameter specifies a position relative to the
last target position (whether it was reached or
not).
If parameter
19-28 Index Trajectory Type
=
[2]
Touch probe positive
, the application moves in
the positive direction until a touch probe
position is defined. If a touch probe position is
already defined, the application moves directly
to that position.
A touch probe position is defined as the
position at which the
touch probe switch
input
goes high plus the value of parameter
19-24
Index Target Position
.
A touch probe position is cleared by a high
signal on the
reset touch probe position
input.
The output
Touch probe position locked
is high
if a touch probe position is defined.
If parameter
19-28 Trajectory Type
=
[3] Touch
probe negative
, the application moves in a
negative direction until a touch probe position
is defined. If a touch probe position is already
defined, the application moves directly to that
position.
NOTICE
This parameter is automatically updated depending on
parameter
19-23 Index Number
.
