EM-RES-03 10/0754
Operation mode "11 – unipolar"
In operation mode "11 – unipolar“, the characteristic points are displaced to the origin
of the characteristics with a negative value for the X-axis.
Characteristic point 1:
X1 = -70.00% · 10 V = -7.00 V
Y1 = -50.00% · 50.00 Hz = -25.00 Hz
Characteristic point 2:
X2 = 80.00% · 10 V = 8.00 V
Y2 = 85.00% · 50.00 Hz = 42.50 Hz
Tolerance band:
ΔX = 2.00% · 10 V = 0.20 V
(X2=80% / Y2=85%)

The characteristic point 1 has been dis-
placed to the origin. The parameter
Tol-
erance band
560 is not taken into ac-
count in this example, as no chan
ge of
sign of the reference frequency value
takes place.
Characteristic point 1:
X1 = 30.00 % · 10 V = 3.00 V
Y1 = -50.00 % · 50.00 Hz = -25.00 Hz
Characteristic point 2:
X2 = 80.00 % · 10 V = 8.00 V
Y2 = 85.00 % · 50.00 Hz = 42.50 Hz
Tolerance band:
ΔX = 2.00 % · 10 V = 0.20 V

The change of direction of rotation is done
in the example at an analog input signal of
4.85 V, with a tolerance band of ±0.20 V.
