FFVEL + PID enabled Setting this parameter to “2” will prompt the program to calcu-

late the optimal setting of parameter velocity feed forward,
proportional, derivative and integral factor.
P3280 Maximum Velocity
P3200 OR 3202 encoder type
P3201 OR 3203 encoder resolution
P1914 motor/encoder gear ratio numerator
P1915 motor/encoder gear ratio denominator

NB!

If any one of these parameters are changed, prompt a recalculation, since the op-
timum value of the regulation parameters will have changed.

19-20 Factory reset

Option:

Function:

[0]

*

Disabled

The parameter automatically resets to “0” when the reset is
successfully carried out.

[1]

Enabled

By setting this parameter to “1” it is possible to reset all param-
eter values to default. This also resets all trajectory data.

19-21 Link LCP input to index

Option:

Function:

[0]

*

disabled

The function is deactivated when set to “0”. This is necessary
when programming a position number different from the one
loaded into the PLC memory.

[1]

*

enabled

When activating this function (1) INDEX NUMBER will be auto-
matically updated with the last position reference number that
has been loaded into memory. This enables to operator to see
what position reference is currently given by the PLC system.

19-23 Index number

Range:

Function:

0

[0 … 31
0 … 63 in fieldbus
mode]

Specify which position data that should be displayed in par.
19-24 to par.19-28. Whenever this number is changed the cur-
rent values of the Index Parameters are stored in memory under
the previously specified index number. After that, the values of
the index parameters are updated with the data stored in mem-
ory relevant to the newly specified index number.

19-24 Index target position

Range:

Function:

0

[-1,073,741,824 …
1,073,741,824 UU]

The meaning of this parameter depends on the position type
specified in TRAJECTORY TYPE.

If TRAJECTORY TYPE = 0, the value of this parameter refers to
an absolute position (relative to the fixed HOME position).
