Parameter Descriptions
3-03 Maximum Reference
Enter the maximum reference. The maximum reference is the
highest value obtainable by summing all references.
The maximum reference unit matches:
•
The configuration selected in parameter 1-00 Configu-
3 3
ration Mode: For [1] Speed closed loop, RPM; for [2]
Torque, Nm.
•
The unit selected in parameter 3-00 Reference Range.
If [9] Positioning is selected in parameter 1-00 Configuration Mode,
this parameter defines the default speed for positioning.

3-05 On Reference Window
Enter the tolerance window for on reference or on target status.
Depending on the option selected in parameter 1-00 Configu-
ration Mode, this parameter defines the following:
•
Speed mode: Speed window for on reference status.
•
Torque mode: Torque window for on reference status.
•
Position mode: Speed window for on target status. See
also parameter 3-08 On Target Window.

3-06 Minimum Position
Enter the minimum position. This parameter defines the position
range in linear axis mode (parameter 17-76 Position Axis Mode)
and in the position limit function (parameter 4-73 Position Limit
Function).

3-07 Maximum Position
Enter the maximum position. This parameter defines the position
range in linear and axis modes (parameter 17-76 Position Axis
Mode).
Position range limits:
•
Linear: Parameter 3-06 Minimum Position to
parameter 3-07 Maximum Position.
•
Rotary: 0–parameter 3-07 Maximum Position.
The position limit function uses this parameter
(parameter 4-73 Position Limit Function).

3-08 On Target Window
The frequency converter considers the positioning completed
and sends the on target signal when the actual position is within
parameter 3-08 On Target Window for the duration of
parameter 3-09 On Target Time and the actual speed is less than
parameter 3-05 On Reference Window.

[0 - 60000 ms]
Function:
Enter up to 8 different preset references (0-7) in
this parameter, using array programming. The
preset reference is stated as a percentage of the
value Ref (parameter 3-03 Maximum Reference).
MAX
If a Ref different from 0
MIN
(parameter 3-02 Minimum/Offset Reference) is
programmed, the preset reference is calculated
as a percentage of the full reference range, that
is on the basis of the difference between Ref
and Ref . Afterwards, the value is added to
MIN
Ref . When using preset references, select
MIN
