Then, for the specified values of p50111 and r50072[1], a search is made for the
associated voltage value in the characteristic diagram.
Below is an example for determining p51578 for
p51570 =
6RA7091-6FC00-0
p50101
= 470 V
p50111
= 0.23 mH
r50072[1] = 890,0 A
According to p51570 and r50071, characteristic diagram 4 (4A) should be used. As
abscissa value, the next lower grid value of 0.22 mH is used as an approximation,
instead of P50111 = 0.23 mH. For r50072[1] = 890.0 A, a linear interpolation is
made in the associated current range 800 A to 900 A. The next higher ordinate
grid value for 380 V is used here as an approximation.
As a consequence, p51578 = 380 V should be set.
If the armature circuit inductance according to p50111 exceeds the value range
shown in the characteristic diagram, then the value should be determined for the
maximum value of p50111 that is shown.
Depending on the values of p50111 and r50072[1], the voltage value being
searched for can lie outside the upper or lower limit shown in the characteristic
diagram.
The upper limit shown in the characteristic diagram is valid for a value of p50351 =
-20 % of p50078[0] (according to the factory setting). The following upper limit
applies for a value of p50351 that deviates from the factory setting:
