F It sets, in Volts, the max. armature voltage the motor achieves in case of an
armature feedback, when the voltage reference is equal to 100%.
WARNING
A software lock exists avoiding to decrease par. P011 value under the value set
in par. P088 (RxI).
WARNING
For this parameter, never save a parameter lower than the one saved in
EEPROM for P088 in order to avoid the drive malfunction.

This parameter sets the allowable polarity both for the Ref n reference applied to
the ramps and for the n setpoint global speed / voltage reference resulting from
the algebraic sum of all the applied references.
0:Bipolar. Bipolar reference.
1:Positive only. Positive reference only.
2:Negative only. Negative reference only.
If you program a unipolar global reference, the possible reference of the
opposite polarity will be shut and considered as equal to zero.
This parameter has no effect either on the jog internal references, that may have
a dual polarity with no min. values, or on the possible offset on the speed error
set through parameter P087.
In order to enter a positive (P014) or negative (P016) min. speed / voltage
reference, you need to first program P012 = 1:Positive only or P012 =
2:Negative only respectively.
In order to change P012 value, both parameters P014 and P016 are to be equal
to zero.
If a certain min. reference other than zero is saved in EEPROM (parameter P014
or P016), in P012 do not save any value that does not match the polarity of the
said min. reference, as this will cause the drive malfunction.
