2.2 List of parameters
For index 4:
P = U2 * I_ext (I_ext = value according to p55156)
The power is calculated from the voltage measured at side 2 and the externally measured current at side 2.
The result is the power that is either issued or fed in at side 2.
For index 3 ... 4:
These indices only supply sensible values if there is an external current measurement at the appropriate side and
p55156 is correspondingly set.
Description: Display and connector output for the actual value of the current at side 1.
Note: The current actual value sensing in SINAMICS DCP measures the reactor current.
The current at side 1 is calculated from the reactor current actual value.
If U1 <= U2:
- current at side 1 = reactor current actual value.
If U1 > U2:
- current at side 1 = reactor current actual value * U2/U1.
Explanation:
U1: voltage at side 1
U2: voltage at side 2
All values are referred to rated device quantities (rated current, rated voltage, rated power).
Description: Display and connector output for the actual value of the current at side 2.
Note: The current actual value sensing in SINAMICS DCP measures the reactor current.
The current at side 2 is calculated from the reactor current actual value.
If U1 <= U2:
- current at side 2 = reactor current actual value * U1/U2.
If U1 > U2:
- current at side 2 = reactor current actual value.
Explanation:
U1: voltage at side 1
U2: voltage at side 2
All values are referred to rated device quantities (rated current, rated voltage, rated power).
Description: Display of the actual value for the current at side 1.
