D
This parameter sets the polarity allowed for REF main reference between
F
terminals 5 and 7 AFTER applying Gain and Bias operators. This is true only if
this input is a speed / voltage reference, i.e. when the digital input programmed
for the 6:Slave function is open (see par. C130 ... C135).
0:Bipolar. Bipolar reference.
1:Positive only. Positive reference only.
2:Negative only. Negative reference only.
If you program a unipolar REF reference, the reference of the opposite polarity
will be shut and considered as equal to zero.

D
This parameter represents, as a percentage of the max. value corresponding to
F
10V, the reference value obtained when the signal applied to the REF main input
between terminals 5 and 7 is equal to zero. Signal V 2 obtained when applying
the Gain and Bias operators to signal V 1 is given by the following formula:

This parameter represents the amplification which is internally applied to the

the Bias. Signal V 2 obtained when applying the Gain and Bias operators to
signal V 1 is given by the following formula:
