86 EM-ABS-01 for ACU 03/12
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.

Point 1:
X1 = -70.00% · 10 V = -7.00 V
1 = -50.00% · 50.00 Hz = -25.00 Hz
Point 2:
X2 = 80.00% · 10 V = 8.00 V
2 = 85.00% · 50.00 Hz = 42.50 Hz
Tolerance band:
ΔX = 2.00% · 10 V = 0.20 V
Point 1 has been shifted into the ori
in.
The parameter
Tolerance band 560 is no
taken into account in this example, as no
chan
e of si
n of the reference frequency
value takes place.

1 = -50.00 % · 50.00 Hz = -25.00 Hz
Point 2:
X2 = 80.00 % · 10 V = 8.00 V
2 = 85.00 % · 50.00 Hz = 42.50 Hz
Tolerance band:
ΔX = 2.00 % · 10 V = 0.20 V
The direction of rotation is chan
ed in this
example at an analog input signal of 4.85
, with a tolerance band of ±0.20 V.
